Formula & Theory — Word Calculator
The Word Calculator uses the following logic for each metric:
- Characters —
text.length, including spaces and newlines. - Chars (no spaces) — characters after removing all whitespace (
\s). - Words — non-empty tokens produced by splitting on whitespace. The Word Calculator considers every run of non-whitespace characters as one word.
- Sentences — segments that end with
.,!,?,。,！,？, or…. If no sentence-ending punctuation is found but the text is non-empty, the Word Calculator treats the entire text as one sentence. - Paragraphs — blocks of text separated by one or more blank lines.
- Spaces — characters matched by the
\sregex class (space, tab, newline, etc.). - Punctuation — ASCII punctuation characters plus common Chinese punctuation marks.
- Reading time ≈
⌈words ÷ 225⌉minutes, based on the 225 wpm average adult silent reading speed. The Word Calculator shows< 1 minfor very short texts.
