Proofreading marks and symbols, also known as editing marks, are the strange red pen scratches that an editor or proofreader applies to a written piece of work to let the writer know what needs to be fixed. From missing periods to misplaced commas, paragraph breaks, and parts to omit, these marks act like a secret code between the editor and writer.

If you’re a writer looking to work with a professional editor or proofreader or to start offering these services to writers, you need to understand what these symbols mean.

When I initially started collaborating with an editor and using a proofreading service, I had no idea what any of the symbols were when I got my draft back full of weird marks. It took a while to learn them all, and now I’m putting them together with a breakdown of each.

My guide lists each proofreading mark and symbol and defines them with quick explanations and a handy image as a visual reminder. I’ll even include some tips on how to use proofreading symbols.

Ready to master the 29 most common proofreading marks and symbols? Let’s get started!

What Are Common Proofreading Marks and Symbols?

Are you ready? Like, really ready? This list is long but includes every main proofreading mark and symbol you might need to know.

Delete or Take Something Out

The delete symbol is commonly used in proofreading to indicate the removal of a word or letter. It helps identify over-repeated words, unnecessary adverbs and adjectives, and overused terms within the text.

Insert

The caret symbol indicates where a word or element should be added to the text. It suggests inserting a word or element to improve the sentence’s clarity or completeness.

Close Up Space

Proofreaders use this symbol to indicate the correction of unequally wide or double spaces in writing. Remove or close the extra space between words if you see this symbol.

New Paragraph

New Paragraph

This symbol signals the need to start a new paragraph. It’s commonly used in dialogue exchanges in stories or when the writer introduces a new idea in their essay.

Add Space

The number or pound sign indicates that you should add space between the two words. It’s commonly used to correct missing spaces, especially in compound words.

It is used to indicate that two characters, words, or sections should be swapped in position.

Change To Capital Letter

Use this proofreading symbol if a word should start with a capital letter instead of lowercase letters. You can also use the sign for multiple capital letters in the word.

Set in Lowercase

This symbol indicates that a word should start with a lowercase letter instead of a capital one.

Grammarist Article Graphic V12 7

This mark signals that a word should be styled in italics.

Grammarist Article Graphic V12 8

This mark indicates that a specific word should be formatted in bold typeface.

Grammarist Article Graphic V12 9

It’s a Latin term that means “let it stand.” Proofreaders use stet to warn the writer to disregard a previous correction or deletion.

Grammarist Article Graphic V12 12

This mark indicates that the beginning of a paragraph should be indented. One square represents a one-space indent, while two squares side by side indicate a two-space indent.

Align Horizontally

Aligh Horizontally

This proofreading symbol is used to let the author know that the text is not horizontally aligned and may need adjustment to ensure proper alignment.

Align Vertically

Aligh Vertically

This symbol indicates that the text within those lines should be adjusted or aligned vertically with nearby text or elements on the page for better visual consistency and readability.

Center Text

Grammarist Article Graphic V12 10

It indicates that the text should be centered on the page. It is typically used for titles, headings, or any text that requires center alignment for aesthetic or formatting purposes.

Grammarist Article Graphic V12 11

This mark lets the writer know that numbers or abbreviations should be fully written in words, especially if they follow certain style guides.

Move Left/Right/Up/Down

Grammarist Article Graphic V12 13

  • The move left symbol suggests that the text should be shifted to the left for proper alignment.
  • The move right symbol indicates a need to shift the text to the right.
  • The move up symbol signifies that the text should be moved upward.
  • The move down symbol denotes a need to move the text downward.

Reduce Space

Grammarist Article Graphic V12 14

Editors and proofreaders use this to tell the writer that the spaces between words or letters should be reduced.

Delete and Close Up

Grammarist Article Graphic V12 15

This mark is used to indicate that a letter should be deleted and that no space should be left behind.

Insert a Hyphen

Grammarist Article Graphic V12 16

It is used to indicate that a hyphen should be added where one is missing between words or in compound modifiers.

Insert a Period

Grammarist Article Graphic V12 17

It indicates that a period should be added where one is missing at the end of a sentence.

Insert a Comma

Grammarist Article Graphic V12 18

It shows where a comma should be added to improve sentence clarity or grammatical correctness.

Insert Quotation Marks

Grammarist Article Graphic V12 20

This symbol is used to add missing quotation marks at the beginning and end of direct speech or quotations.

Insert Apostrophe

Grammarist Article Graphic V12 19

Editors use this one to show where an apostrophe is needed, like in contractions, or to indicate possession.

No Paragraph

Grammarist Article Graphic V12 21

It’s a symbol used when a new paragraph has been incorrectly placed, and the text should continue without a break.

Push to the Next Page/Line

Grammarist Article Graphic V12 24

Editors will use this mark when the text or paragraph should be moved to the beginning of the next line or page to improve layout or readability.

Pull to Previous Page/Line

Grammarist Article Graphic V12 23

This symbol suggests pulling text back to the end of the previous line or page for better formatting or coherence.

Circled Number

Grammarist Article Graphic V12 22

When you see numbers in circles, these indicate multiple instances of the same correction.

How to Use Proofreading Marks

Whether you’re old-school with pen and paper or tech-savvy on the latest digital platform (or a combo of both, like me!), mastering these symbols is your rite of passage into the editing community. Here are some basic tips to help you become more familiar with using them.

Guidelines for Applying Proofreading Marks on Physical Manuscripts

  • Grab a pen: Red is best, but any color will do as long as it’s not black or blue. Tradition dictates red, but any color that screams “Look at me!” and is legible will do just fine.
  • Be consistent: Choose your symbols and stick with them. Changing halfway through is like switching languages mid-conversation.
  • Clarity is key: Your squiggles, lines, and loops should be unmistakable. If it looks like ancient hieroglyphs, you’re doing it wrong. These marks are meant to make the editing process easier and quicker, but if the editor scribbles too much, the writer won’t understand what they mean.
  • Margin notes are a reliable friend: Sometimes, a symbol just won’t cut it. Feel free to jot down a note in the margin for extra clarity.
  • Double-check your work: Once you’ve marked it all up, go back and ensure you got everything, or mark something you didn’t mean to.

Tips for Using Proofreading Symbols in Digital Editing

  • The Track Changes feature is your bestie: Most word processors have it, and it’s a game-changer for digital editing. When turned on, Track Changes will literally track and mark everything you change.
  • Comments gold: Unsure about something? Leave a comment in the document attached to the text in question. It’s like margin notes but without the risk of smudging.
  • Highlight like it’s going out of style: Use different color choices to highlight text and show various types of edits or to prioritize changes.
  • Shortcuts and macros save lives: It may not be as dramatic as that, but they definitely save time. Learn the shortcuts for common editing commands in your word processor so that you never have to stop and search.
  • Embrace editing software: Tools like Grammarly and ProWritingAid are designed to make digital editing a breeze. Find your match and learn its ins and outs. Psst! I highly recommend Grammarly.

Another option is to use a proofreading mark plugin. This allows editors to proofread on word processors without having to memorize every single one of these symbols.

To insert the plugin, open your browser and go to the Greg Maxey website. Select “Resources,” then click “Proofreader Marks Add-in.” You’ll find it at the end of the page.

Then, it will open a dialog box with some prompts you need to follow. Open MS Word and you will see a new “Proofreading Marks: section on the “Add-Ins” tab. Now, you can apply proofreading marks on your document like a professional proofreader.

When proofreading, you must drag the cursor over the text that needs a mark. Then, select the drop-down menu under the ribbon and choose the correct mark. Remember to save your changes.

Transitioning from Traditional to Digital Proofreading

Gone are the days when editing meant paper cuts, White-Out, and red ink-stained fingers. Welcome to the digital age, my friends, where proofreading has gone electronic! But don’t worry; the basics of proofreading remain the same, even if the tools have evolved.

Traditional marks now have their digital counterparts: strikeouts, insertions, comments, etc. Software and digital platforms have embraced these age-old practices, ensuring that even in a world of screens, the heart of editing beats on.

What Do Proofreading Marks Mean?

About the author.

Reedsy's editorial team is a diverse group of industry experts devoted to helping authors write and publish beautiful books.

About Dario Villirilli

Editor-in-Chief of the Reedsy blog, Dario is a graduate of Mälardalen University. As a freelance writer, he has written for many esteemed outlets aimed at writers. A traveler at heart, he can be found roaming the world and working from his laptop.

Having your work come back from an editor covered in red pen is daunting to begin with. Receiving a manuscript that's covered in proofreading marks that might as well be hieroglyphics can be even more intimidating.

But before you reach for your cipher wheel, remember that the purpose of proofreading marks isn’t to confuse you. It’s to provide a detailed roadmap to a professional and polished final manuscript . While independent authors are not likely to spring for large print runs that would be ruined by more than a couple of typos — proofreading still remains an essential step for most serious self-publishers.

These days, it’s unlikely for the proofreading process to occur via pen-and-paper, meaning that the use of proofreading marks is also becoming increasingly rare. Most proofreaders used tools such a “tracked changes” to flag issues — and many indie authors choose to forgo professional proofers for software such as Grammarly or the simple red, dotted line that signifies a typo in processors such as Microsoft Word or Google Docs.

That being said, screen fatigue is a real thing, and there’s something about a hard-copy document that seems to draw the eye to errors more than a digital one. So if you’re working with a proofreader and want to ensure the collaboration fulfills its top potential, it’s worth getting to know the meaning of the more common proofreading marks.

So, without further ado…

What are proofreading marks?

Proofreading marks are used to highlight spelling, vocabulary, grammatical, and punctuation errors, along with formatting and layout issues.

When proofreaders are editing a hard-copy manuscript, they will leave corrections on both sides of the margins: on the left-hand margins for corrections in the first half of the sentence and on the right-hand side for corrections in the latter half of the sentence. A corresponding mark will also be included in-line to indicate where the issue is.

Alright, now let’s take a look at these formidable editing symbols.

Proofreading marks chart

The following proofreading symbols are taken from The Chicago Manual of Style 17th edition. While in-house style guides may vary from publisher to publisher, these symbols are standard across the industry.

Let’s start with operational marks, which cover everything from spelling to sentence structure to improper spacing.

List showing the marks made by proofreaders for operational purposes

  • The “delete” symbol on its own will refer to a word, while “delete and close up” will refer to a letter in a word.
  • The “let it stand” symbol would be used when more than one round of proofreading was done, and it indicates that a correction or alteration should be ignored.
  • The “transpose” symbol indicates the order of words needs to be changed (spot the transpose problem).

Next up are the punctuation marks, which — you guessed it — indicate that punctuation needs to be added .

Lastly, these are common abbreviations used by proofreaders to indicate issues related to the copy itself.

The importance of proofreading

Ensuring that your book is polished and error-free is just as important to the reader experience as the writing quality. Your book can’t effectively communicate if the reader is constantly paused by spelling mistakes, awkward sentence structures,       or      uneven       spacing.

Here's what these proofreading marks look like in use, when a proofreader returns a manuscript, and when their suggestions have been incorporated:

Proofreading Marks

The ultimate guide to proofreading marks.

If you work in the publishing, transcription, or editing fields, you’ll most likely recognize the standard proofreading marks that are used to annotate written works, but sometimes a symbol will pop up that makes you question everything you know.

Whether you’re a writer who is trying to translate proofreading marks into action or a professional proofreader who needs a refresher on common symbols, this article will de-mystify proofreading marks and their uses.

What Are Proofreading Marks?

a blue background shows the title "proofreading marks" with the main sections listed: Common proofreading marks, proofreading abbreviations, abstract/rarely used symbols, proofreading with microsoft word, proofreading with iAnnotate

Physical copy proofreading uses marks in the left and right margins of the paper and within the double-spaced lines to show changes that need to be made. Today, most of these changes are tracked in a word processor or applied directly to the text.

Most proofreaders and editors use a standard system of marking to make the edits and suggestions easy to understand. Therefore, it’s important to understand what proofreading marks mean and how to translate them into tracked changes.

Here are common proofreading marks found in hard-copy annotation and notes on how they are used in digital annotation.

Common Proofreading Marks

Proofreaders’ marks, though standardized, may vary depending on the region. For example, different proofreading marks are used in different dialects — American English proofreading marks differ slightly from British English styles. However, there are several common marks commonly used by most organizations. The symbols are divided into operational signs, typographical signs, and punctuation marks.

Markings are typically made in the color red, with one mark — accompanied by an abbreviation — in the margin to explain the change and one in the exact place of the error. Some proofreaders annotate in green or another color to avoid making writers feel stressed at the sight of so many red “error” marks on their returned works.

Here’s a rundown of the most common proofreading marks and their most likely variations based on the APA 7th Edition and the Chicago Manual of Style 17th edition standards.

Operational Signs

The image shows proofreading marks that fall under the operational signs category including delete, close up/delete space, delete and close up, let it stand, insert a space, make a space between words equal;make space between lines equal, begin a new paragraph, insert hair space, indent type one em from left or right, letterspace, move right, move left, center, move up, move down, flush left, flush right, align horizontally/vertically, transpose, spell out

Operational proofreading marks or signs indicate changes in text organization. For example, moving a paragraph or splitting it, spelling out a word, or abbreviating.

This section doesn’t include punctuation changes, additions, or subtractions. Operational signs also don’t include text additions or subtractions or text style changes like italics or bolding.

Typographical Signs

The image shows the proofreading marks that fall in the typographical signs category: set in italic type, set in roman type, set in boldface type, set in lowercase, set in capitals, set in small capitals, wrong font;set in correct type, check type image; remove blemish, insert here or make superscript, insert here or make subscript

Typography signs refer to the words in the text. These signs mark the use of capitalization, lowercase letters, italics, bold, roman type, font, and misspellings.

Typography proofreading uses the caret to indicate the location of the change in the text, and usually an abbreviation in the margin of that line. Abbreviations give more information about the needed change, and the caret indicates where the change is needed.

Punctuation Marks

The image shows proofreading marks within the category of Punctuation marks: insert comma, insert apostrophe or single quotation marks, insert quotation marks, insert period, insert question mark, insert semicolon, insert colon, insert hyphen, insert em dash, insert en dash, insert parentheses

Punctuation proofreading marks are often described in the margin with a caret inside the text to show where the change needs to happen. The punctuation marks might also be located within the text and inside the caret with no marginal note.

Some common errors noted by proofreaders are the uses of the em dash, en dash, and hyphen , and inserting the proper mark digitally requires different typing operations depending on the word processor or platform used to write.

How to Use Em Dashes, En Dashes, and Hyphens:

  • Insert em dash — The em dash is the longest dash, and it’s used similarly to the colon, comma, and parentheses to separate clauses. Word processors generally recognize a triple hyphen as an em dash.
  • Insert en dash — The en dash is shorter than the hyphen and longer than the em dash. En dashes are used to denote ranges like dates, distances, or destinations. Word processors generally recognize a double hyphen as an en dash.
  • Insert hyphen — The hyphen is a single dash that’s used to join words. Use a hyphen in compound modifiers when the modifier precedes the word it modifies.

Refer to the dictionary to confirm the use of a hyphen in words because word stylization can change. For example, trends in pop culture changed the word “base-ball” to closed compound “baseball” when the sport was popularized in the US.

Proofreading Abbreviations

The image shows common proofreading abbreviations: spell out in full, faulty diction, sentence fragment, too wordy, awkward construction, verb tense problem, wrong word, run-on sentence, unnecessary repetition

Proofreading abbreviations are common in hard-copy annotating, but they’re useful to annotate digitally too. Abbreviations are usually found in the hard-copy text’s margin, though digital proofreading abbreviations can be found either in the margin or in a comment.

Abbreviations commonly used in annotating include

  • (sp): Spell out in full
  • (dict): Faulty diction
  • (wdw): Too wordy
  • (awk): Awkward construction
  • (t): Verb tense problem
  • (ww): Wrong word
  • (r-o Run-on sentence
  • (rep): Unnecessary repetition

Abstract Symbols

Special characters, or abstract symbols, are rarely used but may be needed in a text to formally denote currency, mathematical processes, legal ownership, and foreign letters or punctuation.

The image shows abstract or rare symbols used in text and how to create them on windows and mac computers: copyright, registered, trade mark, cent sign, british pound, euro, japanese yen, division, degree, plus minus, square root

Word processors and other digital platforms include abstract symbols in the toolbar. You can also use the following keys to input these abstract symbols:

How to Use Proofreading Marks & Symbols with Different Software

If you’re working with a word processor like Google Docs, Microsoft Word, or iAnnotate, use the commenting and Track Changes systems to proofread the work. These systems involve an automatic feedback process that avoids in-text strikethroughs and font changes that call for manual attention.

To leave proofreading feedback that isn’t standardized, straightforward, or otherwise easily understood in a comment or tracked change, use the processor’s Insert Symbol function to insert feedback.

Here’s a basic way to create and use proofreading symbols on Microsoft Word and iAnnotate.

Proofreading Marks in Microsoft Word

Luckily for Microsoft Word users, proofreading on a Mac or PC works the same. Proofreaders don’t need to use traditional proofreading marks on Microsoft Word due to the brilliance of the “Track Changes” feature. This feature allows all users to see suggested edits and changes. The user can then accept or reject the suggestions.

To turn on Track Changes, click on the Review tab, then toggle the switch to turn on Track Changes. You can also find the Tools dropdown menu, then select Track Changes. Choose Highlight Changes for more detailed proofing preferences — like color, spacing, and comment balloon style.

After proofreading, the owner can click the checkmark on the suggestion balloon to apply an edit suggestion, or the X ignores the suggestion and keeps the original text.

You can also go to the Review Pane for a list of overall suggested changes.

You can also save all of your edit versions in one document by clicking Protection < Document, and you can add the optional password to control access.

If you don’t like the suggestion bubbles, a good way to add suggestions is in a comment at the end of the text.

To see a full walk-through, check out this video by Caroline Morris .

Proofreading Marks in iAnnotate

iAnnotate is a popular tool for proofreading because proofreaders are able to mark up a text with a digital pencil, or their finger, in the same way that a physical text would be annotated.

This program also includes the ability to customize the symbols toolbar and the ability to edit and move annotations.

Common proofreading operations available using iAnnotate include:

  • Margin annotations — can be added with the pencil tool, the typewriting tool, or with a photo or sound clip.
  • Text marking — can be done with the highlighter tool, underline, strikeout, and shapes.

The platform doesn’t include pre-made proofreader marks, but the stamp feature offers another way for proofreaders to annotate a document. You can use the stamp to create your own traditional proofreader marks, such as margin abbreviations, and save the stamps to the toolbar for a simplified and personalized proofreading experience.

The iAnnotate user guide can help new users troubleshoot problems, and Proofread Planet has some wonderful walk-through videos to help explain iAnnoate functions.

Proofreading marks and digital suggestions are important to communicate to a writer what needs to be changed in the text and why. Clear edit communication helps with the healthy evolution of the text as well as the writer’s ongoing writing improvement.

Awesome information! Thanks!

You deserve praise for addressing each type of proofreading marks in such a comprehensive way.

I enjoyed your article very much. You have provided a lot of good and interesting information for me and everyone. Thank you very much.

Very useful information presented in a concise way. Thanks!

I have trouble with foreign language symbols. For instance, the Nordic O (Ø) can be done by pressing Alt + 0216, but it does not work for me..because in order to type numbers, I have to hold the shift button as well.

Fantastic resource! This guide on proofreading marks is incredibly thorough and easy to understand. It's a great tool for both beginners and seasoned editors. Thanks for making it so accessible and user-friendly!

Two Proofreading Symbols — In Text and In Margin

Lastly, you should know that many proofreading marks have both a textual mark and a marginal mark. 

  • A textual mark means that the symbol is written on the text to be changed
  • A marginal mark , which is placed in the margin, is a symbol or abbreviation that explains the textual mark. 

However, many editors may forgo the marginal mark, and in many cases, the “marginal” mark will be written immediately above or below the text. That’s the reason your teachers always wanted your essays double-spaced.

Proofreading Marks have Wiggle Room

Now, proofreading marks are not a hard science. Though most “official” organizations, like style guides and big publishing houses, agree upon a number of symbols, there’s plenty of wiggle room—meaning, you will find a lot of variation among sources. 

To illustrate the point, let’s consider insertion, i.e. , putting in a missing letter or a bit of punctuation. 

While many kinds of insertion have their own particular symbols in theory, these rules aren’t always followed in practice. For example, to insert a period, most guides will say the proofreader should draw a period with a circle around it, but to insert a letter or word, a carat (^ or ⌄) is used. Further, to insert a parenthesis, the proofreader will write a parenthesis with two horizontal lines through it. 

However, proofreaders and editors may not always follow these individual rules. Instead, they may use circles or carats at will, or they may only write what they want to be inserted without any extra symbols at all.

Additionally, publishers, editors, and English teachers often have their own systems of proofreading symbols. Personally, I use arrows when I find that material needs to be reorganized, and, following in the footsteps of my middle school English teachers, I will use the abbreviations “CD” and “CM” for “concrete detail” and “commentary.” (Shoutout to Mrs. Randall.)

Proofreading Mark Examples & Symbols in Context

Below, you’ll see a sheet with all the symbols and examples of their usage, as well as what the edited text would look like. (Or, in some cases, might look like — though inserting a period or fixing a word’s spelling is pretty objective, responding to a comment like “awkward” or “too wordy” is more open-ended.)

Publish confidently by proofreading to perfection

Proofreading

“Writing without revising is the literary equivalent of waltzing gaily out of the house in your underwear.” — Patricia Fuller

We’re pretty open-minded, but we generally recommend that writing be at least partially dressed before sharing it with the world.

Now that just about everyone is a writer, just about everyone is a proofreader too, when you think about it. Which is why we believe now is the time to get clear about what exactly proofreading entails in our modern world.

What is proofreading?

Proofreading refers to carefully checking for writing and formatting errors in a text before it’s published. It’s the final step in making sure a piece of writing is as close to “perfect” as possible by double-checking for punctuation and spelling errors, typos, and any inconsistencies. The most important purpose of writing is to communicate your thoughts effectively. This, however, is better suited for the editing phase, not the proofreading phase. While proofreaders will check for clarity in consistency, they’re more focused on minor errors that may have slipped through. When you proofread, you evaluate the content in what will be its final, published form, or a proof. (Get it now?) Proofreaders look at more than just the words — they’re scanning for any formatting errors as well. Proofreading marks are either made on paper, or in comments and digital notes in Google Docs and word processing software, to alert the writer of suggested corrections within a document. There are both US and UK English conventions for proofreading. The final step of any personal or business writing process, proofreading is the process of identifying and correcting spelling, grammar, and punctuation errors.

The difference between proofreading and editing

It’s important to note that proofreading and editing are not the same. Editing involves a different skill set and is usually more time-consuming. Though there are various stages to the entire editing process, copy editing and proofreading are the two most common. Coincidentally, they’re also the two that get mixed up the most. Though developmental, structural, and line editing all deserve their time and place , they’re seen less frequently in the world of digital content creation. These parts of the editing process are better reserved for lengthier works, such as books, investigative journalism, essays, instructional works, and magazine articles. The terms copy editing and proofreading are often used interchangeably by those not familiar with the space. These two are not the same, though, and it’s crucial to be aware of their differences if you’re anyone working with written content.

Copy editing Copy editing takes place before proofreading and involves a more thorough shake down of the content at hand. Copy editors will look for things such as readability, grammar, spelling, style, syntax, and punctuation depending on what style guide they’re following. In this stage of the editing process, it’s okay to offer revisions that will require additional writing.

Examples of what a copy editor might comment: Point out wordy sentences, suggest change in word choice, fix punctuation marks in a sentence.

Proofreading Proofreading occurs after copy editing. Though proofreaders look for grammar and punctuation, they’re also focused on the overall formatting of the piece. They’re the last set of eyes before publication, so it’s their job to ensure the text is as close to perfect as it can get. No drastic changes will happen here — that’s the job of all the editors who came before.

Examples of what a proofreader might comment: Fix bad line breaks, change improper punctuation, point out incorrect page numbers.

How to proofread

Traditionally, proofreading is meant to be a relatively rapid and focused process of making sure writing is free of minor errors, such as typos that may have occurred during a more rigorous round of editing. For online publishing and blogging — which often includes transferring of content from a word processing document to a CMS (content management system) — proofreading includes making sure that formatting is correct. Adhering to a style guide — whether that be the Associated Press Stylebook , Chicago Manual of Style , or your own — is another vital part of the process. Consistency is key, and proofreaders need to be aware of what rules to follow for the given copy.

Common things to double-check when proofreading

  • Links function properly and direct readers to the right pages
  • Words — especially names and organizations — are spelled correctly
  • Formatting appears as it was intended — bolds, italics, indentations, new paragraphs, and fonts are correct
  • Proper punctuation is used throughout
  • Capitalization is correct
  • No “bad breaks,” such as widows or orphans
  • Helpful information such as an FAQ section exists
  • Consistent tenses throughout the piece
  • No subject-verb agreement issues
  • Headline or email subject is clear
  • Citations match the brand style guide
  • No misplaced or misused commas
  • Voice and style are consistent throughout

When is the best time to proofread text?

The best time to proofread is during every project’s final stage, after revisions are done and copy editing has been completed. Proofreading is the last step. If you’re wondering what time is the best, we advise after morning coffee and before your deadline. Because the proofreading process is intended to be the final step before publishing or hitting “send,” the changes should be relatively minor — meaning, catching typos or errors that may have slipped by. In other words, proofreading is not the phase where you should be completely reworking a paragraph or changing the direction of your main points. Proofreading is not the time to decide that you’ve changed your stance on an important topic — that kind of change should happen during the initial planning, thesis-writing, or outline phase of your writing. In this stage, you also shouldn’t completely overhaul a piece of writing from, say, a 1,500-word blog post to a 3,000-word help article. That work should have been done during the developmental editing phase.

Top proofreading techniques and tricks

Ask someone else to proofread for you Get a pair of fresh eyes on your writing. After spending so much time on your work, you’ll be apt to accidentally glaze over errors and typographical errors. It’s like a crooked painting in your house — you don’t notice it until someone else points it out. If you have to proofread your own work, step away Close your document, shut down your computer, and take a break from staring at the screen for a few hours (the longer, the better). Go for a walk, sip some coffee, and you’ll have a fresher set of eyes when you return. Focus on one thing at a time When you’re on high-alert for every type of proofing error, it’s easier to miss some mistakes. Instead, try combing a paper only for punctuation, then again for spelling mistakes, and so on. Come back to it if you’re tired Don’t ever try to proofread at the end of the day when your attention span is nil, and all you want to do is sleep. Sleep on it and try again in the morning. Proofreading with a set of sleepy eyes is as good as not proofreading at all. Print it out Editing a hard copy — and not a digital one — will help you see your writing from a different perspective. It feels different, and putting pen to paper feels more substantive and also satisfying. Read it out loud Reading your own writing out loud is a great way to catch any misspelled words or wonky sentences you might’ve missed before. While it might feel funny at first, you’ll find yourself noticing things such as run-on sentences that you wouldn’t have otherwise when reading it silently. Allot two days to proofread Ideally, proofreading should happen at least two days before a deadline. This ensures that you’ll have enough time to implement changes with one more round of proofing to come. Take into consideration the length of your writing — the longer it is, the longer proofing will take. Use an AI proofreading tool You can use an AI writing assistant to help with proofreading digital content. Nowadays, the top ones on the market are programmed to catch spelling, grammatical errors, and some even help you adhere to your style guide . For example, Writer uses AI to catch and correct common writing mistakes — as well as ones personal to your company’s style guide — and ensure your text is ready to share. Proofreading example Editors and professional proofreaders usually check a printed “proof copy” of the text and make corrections using specialized marks. In the digital realm, proofreaders work with AI writing assistants. Most of these online proofreading and editing services also include plagiarism checkers to identify duplicate content on the web and provide an efficient solution for the publication.

Improve your proofreading skills with Writer

With edits occurring more frequently in the “tracked changes” on Microsoft Word or in suggestions on shared Google Docs, proofreaders find themselves doing their job digitally. And in a world flooded with copy and content, it’s crucial to ensure your words stand out, for all the right reasons. Writer is much more than just a spell check — think of it as your very own professional proofreader. And if you’re looking to implement language and content consistency company-wide, Writer has that too. Take your proofreading up a notch by publishing a living, breathing style guide that Writer implements almost anywhere you produce copy. With terminology management , custom writing style rules, snippets, and more, you don’t ever have to worry about your content being flooded with errors.

Whether you need a distraction-free environment, some chill relaxing sounds or a pomodoro timer to manage your time we got you covered.

Got questions? We have answers.

No. Typely is completely free and we plan on keeping it that way. We are considering some advanced features however that might be available under a premium plan.

The only limit we have applied thus far is on the number of characters you can submit and that is being set at a maximum of 50,000.

In theory yes but that will require a lot of work and professionals dedicated for this job. We are considering a way of letting the community participate somehow.

Typely does not do grammar checking because it's hard and almost impossible to get right. The aim for Typely is to be precise and reliable.

All online proofreading and copy-editing services on Wordy is done by professional, first-language editors based in the UK, US, and Australia. Each job has its own webpage with a messaging system, so that you can get in touch with your editor – and they with you – at any point in the process. This is great for last-minute changes or when signing off on a job. The messaging page stays open for up to three days after the editor has delivered the job, so if you have any questions – ask them!

Especially online proofreading and copy-editing services are all about understanding the context and concept of your text, and adhering to the tone of voice and rules you’ve already laid down when you send through your document. In our humble opinion, it really takes a skilled, intelligent editor to make the best of your text and ready it for publication. We do rely heavily on technology to make job processing and assigning on Wordy as straightforward as possible, but when it comes to online proofreading, it’s all about good old elbow grease. There aren’t any secrets to it; just the accumulated editing experience of more than 2,000 years. Wordy adheres to the professional and ethical standards laid out by the Chartered Institute of Editing and Proofreading in the UK and The American Copy Editors Society in the US.

If you’re representing a company or an educational institution, the chances are that you’re not used to paying per delivery for your proofreading services, but instead receive an invoice once a month for the jobs you’ve actually processed. We can set up an open credit account for you, which will invoice individual users of the account or an account owner. We’re also here to step in as account managers, if you want to set up a copy-editor team to handle all your jobs or upload a house style you’d like us to follow. Do get in touch if you want to know more about our credit accounts for companies and educational institutions.

We provide online proofreading and copy-editing services to clients from all over the world, but as a company we are located in London. That means that tech support and client support are there for you during UK business hours, from 9 a.m. to 5 p.m. GMT – and as quickly as possible the following business day. In short, we’ll reply to your questions or comments as fast as we can, but do note that headquarters staff need our beauty sleep, too. Proofreaders are, of course, available 24/7.

Several things are taken into account. First, how many words does the document contain? Second, are you requesting just proofreading and editing or additional services, such as rewriting or an express delivery? The cost also increases if you have a house style guide that you want editors to refer to, or if you restrict the availability of your job to a team of editors that you have selected. The best way to get an estimated turnaround time for your document is to upload it for an instant price quote and approximate delivery time .  If the turnaround time and quote are acceptable, you can continue with the purchase and place the order. If not, no further commitment is required.

Most of Wordy’s larger proofreading clients are invoiced for their usage at the end of each month. If an account has multiple users, we can invoice each user separately, or send the invoice to a single point of contact – for example accounts payable. Standard payment terms are 30 days net. We’re happy to help you set up your account, add additional users, upload your house style (if applicable) and set up an editor/proofreader team. In addition, we’ll be happy to sign a service-level agreement (SLA) and/or non-disclosure agreement if necessary. You can read more on the Privacy Policy page , Pricing page , and the editor guides pages for either UK English or US English . To discuss your requirements, please get in touch .

First, we check with you exactly what the problem is. If you have an issue with the quality of the proofreading, editing or rewriting – if you found a number of mistakes, for example – we will remove the editor from the job and forward the text to one of our head editors for a review. If we agree that the text does contain errors, we will ask you if you want a new editor to go through the text again in response to your feedback. We may offer you a full or partial refund based on the number of errors and inconsistencies we find in the edit. Please note that we don’t consider deliveries made later than the approximate delivery time as grounds for a refund. The actual delivery time will depend on the quality of the original text and the file format. To check on progress, you can, of course, always get in touch with your editor via a message on the job page and ask them to let you know when you can expect the job to be completed.

Proofreaders’ Marks (Proofreading Marks) and Symbols

Although most editing and proofreading are performed today using the ‘Track Changes’ feature of Microsoft Word or other commenting tools, you may encounter traditional proofreading marks and symbols on a hardcopy document. In desktop publishing, it is important to understand the meaning of proofreaders’ marks. Both editors/proofreaders and clients, regardless of their backgrounds, should have the same standard marks for easy communication.

Traditional Proofreaders’ Marks (Proofreading Marks) and Symbols

Although most editing and proofreading are performed today using the ''Track-Changes'' feature of Microsoft Word or other commenting tools, you may encounter traditional proofreading marks and symbols on a hardcopy document. In desktop publishing, it is important to understand the meaning of proofreaders’ marks. Both editors, proofreaders, and clients, regardless of their backgrounds, should have the same standard marks for easy communication. That is why a consistent style and common proofreading marks and symbols should be used. These marks and symbols are considered the language that editors and proofreaders speak when they edit or proofread a hardcopy document.

An Overview of Common Proofreaders’ Marks

As we discussed in the ‘‘ The Difference Between Proofreading and Editing ’ ’ article, the purpose of proofreading is to correct all errors in grammar, punctuation, syntax, and spelling in a manuscript. To confirm whether the final version of one’s manuscript contains any minor errors, you need proofreading. However, editing requires extra effort from an editor than does proofreading, because editing aims to improve the academic quality of your paper. Thus, editing involves improvement of the content, overall structure, quality of findings and analysis, simplicity, and referencing of the paper. Editing also aims to correct all errors in grammar, typography, punctuation, syntax, and spelling in a manuscript. In this sense, editing encompasses proofreading; however, strictly speaking, proofreading is the last stage before printing or delivery to the client. In hardcopy proofreading, editors and proofreaders use specific proofreaders’ marks to communicate their revisions.

If you have ever had a hardcopy paper proofread, you are probably familiar with the unexpected typology of your proofreader. The revised version of your document is returned with symbols that seem to be from a different language.

In a revised hardcopy version of a paper, all edits are visibly marked, including corrections, suggestions, and comments. These strange symbols and marks, left by proofreaders to highlight where changes need to be made in the text, allow you to notice all corrections and suggestions.

Proofreading Marks at a Glance

Proofreaders’ marks (also known as proofreading marks) are symbols and abbreviations for correcting typeset pages. The editors and proofreaders place these marks in the margins and in corresponding lines of text. These symbols and marks referring to comments about and suggestions for revisions appear in the margins and text of your manuscript.

In hardcopy proofreading, corrections and suggestions typically appear in the left or right margins, beside the line containing the error. A mark or symbol is also placed in the text to indicate where corrections and changes need to be made. A caret (^), for instance, indicates an addition, whereas a line through the text indicates a deletion or replacement. Proofreading marks are generally written in red ink for the best visibility.

Here is a list of the most common proofreaders’ marks for your reference (the list is taken from The Chicago Manual of Style Online ):

Proofreaders’ Marks versus Track Changes in Microsoft Word

As discussed above, a revised version of a document, full of strange symbols and abbreviations, may seem to have been translated into another language. Understanding this strange language or decrypting the suggested changes might take hours and maybe time-consuming and challenging. It does not have to be anymore, thanks to the ''Track Changes'' function of Microsoft Word. The ''Track Changes'' function in Microsoft Word is a very handy tool for tracking all changes, corrections, edits, and even suggestions and comments by your editor or proofreader.

With this function, your document is returned with all edits visibly marked. All of the edits, including corrections, suggestions, and comments, via the ‘Track Changes’ function, appear in the margins of a revised paper. It is very easy to notice, follow, accept, or reject all the changes and suggestions in the paper. With a tracked paper, you also see some essential comments by the editor or proofreader on the right-hand side of the page.

PDF Proofreading And Editing

Proofreading By The Professionals

Skyscrapers pointing up to the sky.

A Specialist PDF Editing Service

The Portable document format – or PDF – offers a way of presenting documents independent of software or hardware constraints. This makes it one of the most popular document formats in the world. And since PDFs are harder to change than most document types, a good PDF  editing service  is vital.

Make sure your writing is the best it can be with our expert English proofreading and editing

PDF Proofreading Example (After Editing)

Our Process

To take advantage of our PDF editing service, simply:

  • Go to our  upload page
  • Drag and drop your PDF file(s) onto the page or click ‘Browse or drag & drop your file’ to select the file(s) you want to upload
  • Choose either  proofreading  or  editing
  • Enter document details and instructions for your editor
  • Make your payment and let us pair you with the perfect PDF proofreader, who will then check your document
  • Download the edited PDF from your  user area

PDF Proofreading Example (After Editing)

When editing a PDF, we return an annotated copy of your document. The annotations will depend on whether the PDF is layered (i.e. with text you can select with the cursor) or flat (i.e. just an image).

Find out about how we check layered and flat PDFs below.

You can then review every change we make, so you’re always in control of the final draft. And as well as PDF documents, we can work with files from Google Docs to PowerPoint presentations. See our supported formats page for more information.

Layered PDF Proofreading

With a layered PDF, we will use Adobe Acrobat’s annotation features to ‘mark up’ your document (i.e. show you where changes need making). This may include:

Highlighting  – A simple way of highlighting text, accompanied by a comment explaining why the text has been highlighted.

highlighting example

Strikethrough  – This function places a red line through text that should be deleted from the document. We will also leave a comment explaining the deletion if necessary.

proofreading marks online

Insertion Cursor  – Also known as a ‘caret’, we will use this mark if you need to add new text somewhere in your document. We will also suggest the replacement text in a comment.

proofreading marks online

Replacement Strikethrough and Cursor  – These marks show that the selected text should be replaced. We will suggest the replacement text in an accompanying comment.

proofreading marks online

Sticky Notes/Comments  – We use comments for all other situations, such as providing feedback or explaining a problem. To see the comment, all you need to do is click on the little yellow square with its speech bubble.

proofreading marks online

With a flat PDF, your proofreader will only be able to mark up the document using sticky notes/comments. Once you’ve checked our suggested alterations and comments, you can then revise the original document before creating a new PDF.

Super Fast Editing

To make sure you get your document back in time, we offer three levels of service:

So no matter how tight your deadline may be, we have a service for you. Simply select Regular, Express, or Rapid when you upload your document.

Express and Rapid services are subject to availability. If we are unable to provide a service at the time of your upload, its icon will be grayed out in the menu above.
