What is the Paragraph Length Analyzer?

A page of identical 120-word paragraphs is exhausting to read even when every sentence is fine. This analyzer splits your text on blank lines, measures the words, sentences and characters in each paragraph, and draws a bar strip of relative lengths so the shape of the page is visible at a glance.

  • Words, sentences and characters measured for every paragraph
  • Mean, median and standard deviation of paragraph length
  • Configurable wall-of-text threshold with red flagging
  • Bar strip showing relative paragraph lengths in document order
  • Runs of consecutive over-long paragraphs listed separately
  • All processing stays in your browser — nothing is uploaded

How to use the Paragraph Length Analyzer

  1. 1

    Paste your article, chapter or post — paragraphs are separated by blank lines.

  2. 2

    Set the wall-of-text threshold in words, and how many long paragraphs in a row should be flagged.

  3. 3

    Read the mean, median and standard deviation to see how varied your paragraphing is.

  4. 4

    Scan the bar strip: red bars are over your threshold and a flat skyline means low variety.

  5. 5

    Work down the table and break up the paragraphs highlighted in red.

About the Paragraph Length Analyzer

A page of identical 120-word paragraphs is exhausting to read even when every sentence is fine. This analyzer splits your text on blank lines, measures the words, sentences and characters in each paragraph, and draws a bar strip of relative lengths so the shape of the page is visible at a glance.

You get the mean, median and standard deviation of paragraph length, plus a configurable wall-of-text threshold — 150 words suits web copy, more suits print fiction. Paragraphs over the threshold are marked in the strip and the table, and runs of consecutive over-long paragraphs are called out separately, because two in a row is what actually loses a reader.

Everything is measured locally in your browser with JavaScript. Your draft is never uploaded and nothing is stored, so unpublished chapters and client work are safe to paste, and the tool keeps working offline.

Frequently asked questions

How long should a paragraph be?

For the web, most editors aim for 40 to 80 words — roughly three to five lines on a phone. Print non-fiction tolerates 100 to 150, and fiction varies deliberately, dropping to a single line for emphasis. Variation matters more than any single target.

Why does standard deviation matter for paragraphs?

It measures variety. A low standard deviation means every paragraph is about the same length, which reads as monotonous even when the sentences are good. A healthy draft mixes short paragraphs with longer ones, and that shows up as a higher figure.

How does the tool decide where a paragraph ends?

On blank lines, the same convention used by Markdown and by most word processors when text is copied out. If your text uses single line breaks instead, join the lines first or the tool will treat each line as its own paragraph.

What counts as a wall of text?

Any paragraph over the threshold you set, defaulting to 150 words. The bigger warning is the run list — two or three over-long paragraphs back to back with no white space between them is what makes readers scroll away.

Does it work on Markdown or HTML?

It works on Markdown because Markdown separates paragraphs with blank lines. Pasted HTML will be measured as raw source including the tags, so strip the tags first if you want accurate word counts.
