What is the Chapter Word Count Tracker?

Paste a whole manuscript and this tracker breaks it into chapters, counts the words in each, and converts them to manuscript pages and reading time.

  • Chapter detection from Markdown headings, Chapter lines or a custom regular expression
  • Word count, manuscript pages and reading time per chapter
  • Bar chart of chapter lengths with the mean marked
  • Amber flags on chapters more than 1.5 standard deviations from the mean
  • Progress bar against your target word count
  • CSV copy and download, generated entirely in your browser

About the Chapter Word Count Tracker

Paste a whole manuscript and this tracker breaks it into chapters, counts the words in each, and converts them to manuscript pages and reading time. A bar chart shows the shape of the book with the mean marked, so a chapter that runs twice as long as its neighbours is obvious immediately rather than in the first round of edits.

Chapters are found from Markdown headings, from lines starting with Chapter, Part or Book, or from your own regular expression if your manuscript uses something else. Words per page and reading speed are both editable — 250 words per double-spaced page and 238 words per minute are the defaults — and a progress bar tracks the whole draft against your target word count.

Everything runs locally in your browser. Your manuscript is never uploaded, nothing is stored on a server, and the CSV export is generated on your device, so unpublished work stays private.

Frequently asked questions

How long should a chapter be?

Most adult novels run 1,500 to 5,000 words per chapter, with thrillers at the short end and literary fiction at the long end. Consistency matters more than the number — readers notice when one chapter is three times the length of the rest.

How does it find my chapters?

By default it matches Markdown headings, so lines beginning with # or ##. You can switch to matching lines that start with Chapter, Part or Book, or supply your own regular expression such as ^Scene \d+ for a different structure.

How many words are on a manuscript page?

Standard manuscript format — 12pt Courier or Times, double spaced, one-inch margins — works out at roughly 250 words per page, which is the default here. Printed book pages hold more, so change the setting if you are estimating a finished book.

How is reading time calculated?

Words divided by your reading speed, defaulting to 238 words per minute, which is the figure most often cited for silent reading of English prose. Raise it for skim-reading and lower it to about 150 for read-aloud pacing.

What do the amber rows mean?

They mark chapters more than 1.5 standard deviations from your mean chapter length — the ones a reader is most likely to feel as unusually long or unusually short. They are not errors, just the places worth a second look.

Is my manuscript uploaded anywhere?

No. Splitting, counting, charting and the CSV export all happen in your browser with JavaScript. Nothing is sent to a server, so a full unpublished novel is safe to paste.
