Open the Readability Statistics window in Word

Microsoft Word has a built-in readability checker that shows you how difficult your writing is to understand. To see it, go to the Review tab at the top of the window, then click Editor (or Spelling & Grammar in older versions). A panel opens on the right side of your screen.

In that panel, look for a section labeled Readability. If you don't see it, click the three dots or settings icon in the Editor panel and turn on the readability option. Once it's on, Word starts analyzing your document automatically as you type or after you finish writing.

The readability section shows you two main numbers: a readability score (usually between 0 and 100) and a grade level (like "Grade 8" or "Grade 12"). These tell you how straightforward or hard your writing is to read.

Key Takeaways

  • Word's readability checker lives in the Review tab under Editor, and it works automatically once you turn it on.
  • The grade level number tells you what school year a person would need to have completed to understand your writing easily.
  • Shorter sentences, common words, and active voice all lower the grade level and make your writing easier to read.
  • A readability score of 60 or higher and a grade level of 8 or below works for most readers who are not specialists.

What the readability numbers actually mean

The grade level is the most useful number. If Word says your writing is at "Grade 10," it means a person who finished 10th grade should be able to read and understand it without stopping to look up words. Grade 6 is easier than Grade 10. Grade 12 is harder than both.

The readability score (sometimes called the Flesch Reading Ease score) works the opposite way: higher numbers mean easier reading. A score of 90 to 100 is very straightforward (like a children's book). A score of 30 to 50 is hard (like a legal document). Most business writing and news articles aim for 50 to 70.

These numbers are not perfect. They count syllables and sentence length, but they don't understand whether you're using the right word for your audience or whether your ideas actually connect. A sentence can be short and still confusing. Use the numbers as a starting point, not as a final judgment.

How to lower your grade level and improve readability

The fastest way to lower your grade level is to break long sentences into shorter ones. If a sentence has more than 20 words, try splitting it. "The company, which was founded in 1995 and has grown to serve customers across North America, announced a new product line" becomes two sentences: "The company was founded in 1995. It now serves customers across North America and announced a new product line."

Replace difficult words with common ones. Use "help" instead of "facilitate." Use "use" instead of "utilize." Use "end" instead of "terminate." Word's Editor panel often flags these automatically and suggests simpler alternatives.

Use active voice instead of passive voice. "The report was written by the team" (passive, harder to read) becomes "The team wrote the report" (active, easier). Active sentences are shorter and clearer.

Remove unnecessary words. "In order to" means the same as "to." "At the present time" means "now." Every word you cut makes the sentence easier to follow.

When readability scores don't tell the whole story

Readability numbers work well for general writing like emails, blog posts, and instructions. They work poorly for technical writing, poetry, or writing aimed at specialists. A medical journal article might have a Grade 14 level because it uses necessary technical terms, and that's correct for its audience.

The numbers also don't catch unclear organization, missing steps, or ideas that don't connect. You can write short, straightforward sentences that still confuse the reader if they're in the wrong order or if you've left out important information.

Use readability as one tool among others. Read your writing aloud. Ask someone unfamiliar with the topic to read it and tell you where they got stuck. Both of those catch problems that a readability score will miss.

Readability settings and what they control

In Word's Editor settings, you can choose which readability standard you want to use. The default is usually Flesch Reading Ease, but some versions offer Flesch-Kincaid Grade Level (which directly shows grade level) or other standards. They all measure roughly the same thing in slightly different ways, so pick whichever number makes sense to you and stick with it.

You can also set a target grade level in some versions of Word. If you tell it you're writing for Grade 8 readers, it will flag sentences and words that push above that level. This is useful if you're writing instructions for a specific audience.

Frequently Asked Questions

Why does my readability score say Grade 12 when I used straightforward words?

Grade level is based partly on sentence length and partly on word length (syllables). If you used straightforward words but wrote very long sentences, the score stays high. Break those sentences into shorter pieces. Also check whether you used any technical terms or proper nouns that Word counts as "hard" words even if they're familiar to your audience.

Is a lower grade level always better?

Not always. Grade 6 writing is too straightforward for a research paper or a technical manual. Grade 12 is too hard for instructions aimed at the general public. Match your grade level to your audience. For most business and public writing, aim for Grade 8 to 10.

Can I turn off the readability checker?

Yes. In the Editor panel, click the settings icon and uncheck the readability option. It will stop showing up, but you can turn it back on anytime. Turning it off doesn't change your document—it just hides the score.

Does readability work the same way in Word Online as in the desktop version?

Word Online has a simpler Editor than the desktop version. It may not show all the same readability details, but the basic grade level and score work the same way. If you need full readability features, use the desktop version of Word.
