About this tool
Text Statistics Analyzer
Count words, sentences, paragraphs and syllables, then score readability grade for any text.
Text Statistics Analyzer breaks any passage down into words, unique words, characters, sentences, paragraphs and syllables, then runs six standard readability formulas over it — Flesch Reading Ease, Flesch-Kincaid Grade, Gunning Fog, SMOG, Coleman-Liau and the Automated Readability Index. It is built for writers, editors, teachers and content marketers who need to know not just how long a piece is, but how hard it is to read. Everything runs in your browser, so drafts and student work never leave your device.

Frequently asked questions
What is a good Flesch Reading Ease score?
Most general web and business writing aims for 60-70, which reads at roughly an 8th-9th grade level. Scores above 80 feel very easy and conversational, while anything under 30 usually needs a university-level reader.
How are syllables counted without a dictionary?
The tool uses the standard vowel-group heuristic with silent-e and silent -ed corrections. It matches dictionary counts for the large majority of English words, which is exactly the basis the classic readability formulas were calibrated on.
Why do the grade level scores differ from each other?
Each formula weighs different signals: Gunning Fog and SMOG count words of three or more syllables, Coleman-Liau and ARI use character length instead, and Flesch-Kincaid blends sentence length with syllables. Reading them together gives a more reliable picture than any single number.
How does it decide where a sentence ends?
A sentence ends at a full stop, question mark or exclamation mark, or at a line break so that headings and bullet points each count once. Abbreviations such as 'Dr.' can occasionally split a sentence early, which is normal for automated readability scoring.
