A sentence counter counts sentences; a word counter counts words. A paragraph may have 80 words but only five sentences — use both to understand length and structure.

Accuracy is high for standard English with clear punctuation. Abbreviations (e.g. “Dr.”, “U.S.”) can occasionally affect counts — use the sentence breakdown when precision matters.
