📐 Text Analysis

Two standard formula scores. Both use characters per word and sentence length.

Coleman-Liau
Number from formula
ARI
Number from formula

Coleman-Liau and ARI both output a single number from their respective formulas. They use characters per word and sentence length (no syllable counting). Created in 1975 and 1967 respectively, both are still in active use.

FAQ

What is this tool for?

It's a calculator. Paste any text and it returns counts, a reading-time estimate, and the output of six standard text-analysis formulas. The tool reports numbers; it doesn't judge whether the text is good or bad.

What each input / output does

Text input

Paste or type any text (blog post, email, essay, transcript). Stats update live with every keystroke. The toolbar buttons paste from clipboard, clear, or load a sample.

Text highlighter

A live preview of your text with longer sentences color-coded: yellow for sentences with 20+ words, red for sentences with 30+ words.

Words / Characters / Chars (no spaces) / Sentences / Paragraphs

The core counts. Words are whitespace-separated tokens. Characters includes spaces; "Chars (no spaces)" excludes them. Sentences split on . ! ?. Paragraphs split on blank lines.

Estimated reading time

Words divided by 225 (a common publishing convention). Real reading speed varies from 150 to 300+ words per minute, so the estimate is a ballpark.

Coleman-Liau

A 1975 formula that uses characters per word and sentences per 100 words. Computer-friendly because it doesn't require syllable counting.

ARI (Automated Readability Index)

A 1967 formula based on characters per word and words per sentence. Like Coleman-Liau, it uses character counts instead of syllable counts.

General questions

How accurate are the counts?

Word and character counts are within 1–3% of typical word processors (differences come from how each tool handles hyphenated terms, URLs, and contractions). Sentence count may miscount around abbreviations like "Dr."

Why does my word-processor document show a different word count?

Word processors and this tool use slightly different tokenizers; what counts as one "word" varies for hyphenated terms, URLs, and contractions. Differences of 1–3% are normal.
