How it works

Whitespace runs define words, .!? runs define sentences, blank-line runs define paragraphs, and CRLF or LF defines physical lines. JavaScript length supplies UTF-16 units, while cleaned ASCII word forms produce unique-token, type-token-ratio, and hapax counts.

  • Short, medium, and long buckets mean at most 4, 5–8, and at least 9 UTF-16 units, including punctuation attached to a token.
  • Unicode UAX #29 provides linguistic boundary algorithms, but this deterministic summary does not choose a locale or dictionary.

When to use this

Submission forms check approximate limits, editors compare English sentence lengths, and corpus exercises calculate type-token ratios and hapax counts.

Edge cases

  • Chinese prose without whitespace counts as one word even when a reader recognizes several lexical words.
  • 😀 adds two to the character total because that field measures UTF-16 units rather than code points or graphemes.
  • Mr. Smith creates a sentence boundary at the abbreviation period, while a newline alone does not end a sentence.
