Flesch-Kincaid Grade, Gunning Fog and SMOG all estimate the school grade needed to understand the text on first reading — they weight sentence length and complex words differently, so quoting two or three of them gives a fairer picture than any single number.

How to Write More Readably

  • Split long sentences. Anything over 25 words usually hides two thoughts — this tool lists them for you.
  • Prefer short words. utilize → use · approximately → about · demonstrate → show.
  • Active voice. "We tested the tool" beats "The tool was tested by us."
  • One idea per paragraph, front-loaded — readers scan, especially on phones.
