Self-proofreading refers to the process of improving your own written work through the correction of errors, the revision of structure, and the refinement of word choice. Self-proofreading contrasts with the now widespread practice of using proofreading services.

The purpose of a proofreading service is to find and fix every typographical mistake that a document contains. If you’re proofreading your own work, it may be unfamiliar to you that professional proofreaders use dedicated checklists to ensure they work to a high standard.
In a typical professional proofreading checklist, which it is strongly recommended that you use, the following issues are focused on:
- Removing unnecessary words
- Spelling and grammar
- Improving clarity
- Minimising jargon
- Avoiding repetition
- Avoiding long sentences
- Formatting
When you self-proofread your writing, it is crucial to pay close attention to each of the above areas before considering your manuscript complete.

In a professional proofreading service, proofreaders typically follow the 10% rule. Often attributed to the author Stephen King, who wrote about the 10% rule in his book On Writing, the rule states that a first draft can always be cut down in length by 10% without losing any significant meaning.
For example, if your manuscript is 10,000 words long, Stephen King’s 10% rule would suggest that 1,000 of these words can be cut somehow (in this case, through proofreading).
On the basis of the 10% rule, it is always worth trying to maximise the concision of your written work when you engage in self-proofreading. If you can’t pay for professional proofreading services, this is certainly the next best thing.

Another important tip that professionals follow when proofreading, and which you also should try, is to keep your audience in mind – ideally all the time. Writing should always be tailored to the intended audience, which we immediately see when considering the differences between a university essay and an email intended for a colleague.
To help you write most effectively for your target reader, you should ask yourself the following questions:
- Is this written in a way that my reader can understand?
- What would my reader think of this phrase or sentence?
- Are there other suitable phrasings?
One trick that writers often use is to imagine a person that they know well who can serve as a stand-in the general audience. This helps them to visualise their audience and eases the writing and proofreading process.
