Flesch Reading Ease Formula, WPM Reading Speed & Character Limits

Frequently Asked Questions about Word Counter
How does the Word Counter count hyphenated words and contractions?
Whitespace-delimited tokens are counted as single words (`state-of-the-art` and `don't` each count as 1 word), matching the default word-boundary behavior of Microsoft Word and Google Docs.
Why does `String.length` in JavaScript sometimes count emojis as 2 or more characters?
JavaScript strings use UTF-16 code units. Characters outside the Basic Multilingual Plane (such as emojis like `🚀`) require a 2-unit surrogate pair (`length === 2`), and ZWJ family emojis can span 7+ code units.
How is the Flesch Reading Ease score interpreted?
Scores between 60 and 70 represent standard plain English easily understood by 13- to 15-year-old readers. Scores below 30 indicate dense academic or legal prose with long multi-clause sentences.
Can I paste 100,000+ word manuscripts into the Word Counter without freezing the tab?
Yes. The counting engine runs in $O(n)$ linear time inside `useMemo` and processes 100,000 words (~600 KB of UTF-8 text) in under 15 milliseconds locally in your browser.
