Now that you’ve enabled reading statistics, checking the readability score of a document or a selection of text is simple. All you have to do is run a spell and grammar check. You can select specific text to check, or make sure nothing is selected to check the whole document. Initiate a spelling and grammar check by hitting F7 or by clicking the Proofing button in the status bar at the bottom of the window.
Each readability test bases its rating on the average number of syllables per word and words per sentence. The following sections explain how each test scores your file's readability.
This test rates text on a 100-point scale. The higher the score, the easier it is to understand the document. For most standard files, you want the score to be between 60 and 70.
