Why sentence length matters
Readability
Average sentence length is a core input to readability formulas like Flesch-Kincaid and Gunning Fog. Keeping most sentences between 11 and 20 words helps you hit a reading level that works for the widest audience. Shorter is not always better — variety is what creates engaging prose.
SEO impact
Google’s helpful content signals reward pages that are easy to read. Pages with excessively long sentences tend to have higher bounce rates and lower dwell times. By keeping sentence length in check, you improve both user experience signals and your chances of earning featured snippets.
Writing rhythm
Great writing mixes sentence lengths deliberately. A short sentence after a long one creates emphasis. A series of medium sentences builds momentum. This tool’s distribution chart shows you whether your writing has rhythm or monotony — so you can fix it before publishing.
