How do I count the sentences and paragraphs in a piece of writing?

Short answer

Paste the text into a browser-based counter that reports the number of sentences, lines and paragraphs along with the word and character totals. It runs entirely on your own device, so a private draft is never uploaded, and it is free with no sign-up.

Structure counts, not just words

Word count is only part of the picture. Sentence and paragraph counts tell you about pacing and structure: very long paragraphs can signal a wall of text, and average sentence length hints at how easy the writing is to read. For assignments and content briefs that specify a number of paragraphs or sentences, counting them directly beats eyeballing.

Sentences, lines and paragraphs are different units

A sentence counter detects sentence-ending punctuation, a line counter totals the lines including blank ones, and paragraph counting groups the text by blank-line breaks. Knowing which unit a requirement means avoids confusion, and having all of them at once removes the guesswork. Everything is computed in your browser, so the text never leaves your device.

Step by step

  1. Paste your text. Open the sentence counter and paste your writing.
  2. Read the counts. See sentences, lines and paragraphs alongside words and characters, all local.
  3. Edit to fit. Adjust the structure to hit a required number of sentences or paragraphs.

Frequently asked questions

No. The counting runs entirely in your browser, so the text stays on your device.

What is the difference between lines and paragraphs?

A line counter totals every line including blanks; paragraphs are groups of text separated by blank lines.
