What these scores mean

  • Flesch Reading Ease — 0–100. Higher is easier. 60–70 is the sweet spot for general web copy.
  • Flesch–Kincaid Grade — US grade level. Most consumer copy targets 7–9.
  • ARI & Coleman–Liau — grade levels that use characters instead of syllables (less affected by syllable-counting errors).
  • Gunning Fog — emphasises long words. Lower is friendlier.

Syllable counts use a vowel-group heuristic — accurate enough for scoring, but not for, say, poetry.
