Live results

Splits on . ? ! after trim. No closing punctuation yet? The whole paste counts as one sentence. Paragraphs = blocks split by a blank line.

Sentence stats stay in this tab; use Copy report when you need plain-text metrics elsewhere.

Your sentence stats will show here.

The big number is total sentences. Paragraphs, rhythm, reading time, longest and shortest sentence previews, and top openers update live-no upload.

Length & format benchmarks

Use these as sense checks while you edit-not rigid rules. Every app counts characters and “words” a little differently.

  • Blog posts: ~800-2,000 words is a common full-article band before you split into a series.
  • SEO explainers: ~1,000-2,500 words when you need depth, headings, and internal links without filler.
  • Social: ~100-300 characters for a tight single post; threads need clear breaks.
  • Academic abstracts: often ~150-300 words-always match the venue PDF.

What this is for

Use Sentence Counter when you need a fast read on how many sentences you wrote, paragraph breaks, avg length, and run-ons vs choppy lines before you ship prose to an editor or CMS.

  • Spot rhythm issues: shortest vs longest previews and avg words per sentence update live
  • Pair with Word counter or Reading time when pacing or briefs matter
  • Pair with Line counter when your paste is really a list or log, not flowing prose
  • Use Copy report (or CSV/Excel/PDF) when you need the same metrics in email or tickets

Remember: Splits follow . ? !; abbreviations can disagree with Word-use this as a sanity check, not a legal count.

Bookmark this page-editors and students re-check sentence counts all week. One tab beats reopening five apps.

Built for drafts and limits

Use it before you paste into Docs, Word, Notion, or a CMS-every editor guesses sentences a little differently. Here you see exactly what is in the box, refreshed live, with no server round-trip.

How it works

  1. Paste or type in Your text. Live results update instantly (side-by-side on wide screens, stacked on mobile).
  2. Read the large sentences total first, then paragraphs, words, rhythm, reading time, shortest vs longest sentence, and top openers (section is always visible; rows fill in as you add sentences).
  3. Use the gray What this means / Next box under the stats, then Copy report to export plain-text metrics.

What each metric means

  • Sentences - regex split on terminal punctuation; abbreviations (e.g. “Dr.”) can differ from Word.
  • Paragraphs - one or more blank lines between blocks.
  • Avg / min / max words - per detected sentence; flags run-ons vs choppy fragments.
  • Reading time - ~200 wpm from total words; tune with Reading time.
  • Top openers - first word of each sentence; pairs with Word frequency for deeper repeats.
  • Shortest preview - shown when you have two or more sentences and the shortest is shorter than the longest (same rules as min/max word counts).

Privacy: Your paste is not sent to us for counting; it stays in this tab until you reload, clear, or copy it yourself.

FAQ

  • Is my text uploaded? No-everything runs in your browser until you choose Copy report.
  • Do I need an account? No sign-in; the tool is free.
  • Why do counts differ from Google Docs or Word? Hidden formatting and smart punctuation change splits; this page uses the characters you paste.
  • What does Copy report include? Plain-text lines: sentences, paragraphs, words, lines, averages, min/max, sentences per paragraph, reading time.
  • Can I use it on my phone? Yes-the layout stacks; paste, edit, and copy the same way.
