Worked example
The sample paragraph about learning to code has 46 words in 6 sentences and 65 syllables. Its Flesch Reading Ease is 79.5, which is Fairly easy. The formula is 206.835 − 1.015 × (words ÷ sentences) − 84.6 × (syllables ÷ words): 206.835 − 1.015 × 7.67 − 84.6 × 1.41 gives 79.5. The Flesch-Kincaid grade is 4.1, Gunning Fog 5.7 and SMOG 7.2; only three words have three or more syllables (carefully, exactly and ideas).
Coleman-Liau and ARI count letters instead of syllables, so they score a little differently: 9.1 and 5.4 here.
What the scores mean
- Reading Ease: 60–70 is plain English; above 80 is easy; below 50 is hard going for most readers.
- Grade scores estimate US school years needed: 8 means a 13–14 year old could follow it.
- Web content usually aims for Reading Ease above 60 or a grade around 7–9.
All six formulas were designed for English and reward short sentences and short words, nothing else. They cannot tell if your text is accurate, well organised or right for your reader, and technical terms like JavaScript lower scores even when your audience knows them. Syllables are estimated with rules, so scores can differ by a point from other tools. Check length with the word counter and repeated words with the word frequency counter.
