Sentence Counter

Summary

Sentence Counter analyses pasted or typed text and returns a complete breakdown: sentence count, paragraph count, word count, character count (with and without spaces), average sentence length in words, and average words per paragraph. All processing happens in your browser — nothing is sent to a server.

How it works

1. Paste or type your text into the input box.
2. The tool splits text into sentences at terminal punctuation (. ! ?) followed by whitespace, allowing for common abbreviations like "Dr." or "U.S."
3. Paragraphs are counted by splitting on blank lines; words and characters use whitespace-split and string-length.
4. Sentence, paragraph, word, and character totals appear instantly, with average sentence length and words per paragraph.

Use cases

• Check whether academic or business writing meets required sentence-length guidelines.
• Evaluate readability by spotting overly long average sentences in draft copy.
• Count paragraphs and words in an essay before submitting to a word-limited form.
• Audit newsletter or blog posts for paragraph balance and sentence variety.
