Readability Analyzer

Estimate reading difficulty with several standard formulas.

Every score here is an estimate. All of these formulas work from sentence length and syllable or letter counts — they cannot tell whether the writing is accurate, well organised or actually clear, and a short sentence of pure jargon will score well. They were also calibrated on English prose, so they say little about code, lists or other languages. Use them to find passages worth rereading, never as a target to optimise.
