Compteur gratuit de phrases et de paragraphes. Affiche les totaux, la moyenne des phrases par paragraphe, le paragraphe le plus long et un histogramme de longueur de paragraphe.

Quand l’utiliser

Use the sentence and paragraph counter for blog editing, content audit, web copy review, or any context where paragraph length affects readability. Essential for long-form writers checking pacing.

Comparaison

Single-purpose counter that complements the comprehensive stats already shown in the sidebar. Useful when paragraph structure (not just word count) is what you're auditing.

Comment ça marche

The counter tokenizes paragraphs (default: blocks separated by blank lines) and sentences within each paragraph.

Outputs total counts, average sentences per paragraph, longest paragraph (and its position), and a per-paragraph length histogram.

Toggle single-newline mode if your source treats each line break as a paragraph break.

FAQ

Why isn't my paragraph count right?

By default, paragraphs are separated by blank lines (double newlines). Toggle single-newline mode if your text uses single line breaks for paragraphs.

What's a good paragraph length?

For web/blog reading, 3-5 sentences per paragraph. Academic and book prose often runs longer. Very long paragraphs scare web readers.

How does sentence detection work?

End punctuation (. ! ?) followed by whitespace and a capital letter. Abbreviations and decimals can confuse the detector.

Exemple concret

Entrée

A blog post with 8 paragraphs and 32 sentences.

Sortie

32 sentences across 8 paragraphs — avg 4.0 sentences / ¶. Longest ¶: 7 sentences.

Most blog posts read best at 3-5 sentences per paragraph. The longest paragraph (7 sentences) is a candidate for splitting.

Pièges courants

  • Paragraph detection depends on newline conventions — toggle single-newline mode if your source uses single line breaks.
  • Sentence detection breaks on abbreviations and code samples.
  • Very long paragraphs scare web readers — aim for 3-5 sentences per paragraph.
  • Headers and bullet items often count as single-sentence paragraphs.
