Frequently asked questions

How are syllables counted?▾

We use a vowel-group heuristic: count groups of contiguous vowels, with corrections for silent 'e' and short words. It's about 90% accurate for English prose.

What's a good Flesch Reading Ease?▾

60–70 is plain English suited to most adults. 50 is fairly difficult, 30 or below is very hard. Most newspapers target 60–70.

Does it work on non-English text?▾

Word and sentence counts work, but readability formulas are calibrated for English. Use them as rough indicators only for other languages.
