The usual lengths
The same text against every target, with any range you changed above. These are common starting points, not rules: an agent's, publisher's or contest's own guidelines come first.

|---|---|---|
| Back-cover blurb | 150 to 200 words | 0 wordsNothing yet |
| KDP book description | Up to 4,000 characters | 0 charactersNothing yet |
| One-page synopsis | 500 to 700 words | 0 wordsNothing yet |
| Elevator pitch | 25 to 50 words | 0 wordsNothing yet |
- Back-cover blurb. Common guidance for the back of a paperback: enough to set up the story and fit the cover.
- KDP book description. Amazon’s limit for the description box. It is a ceiling, not a target, and formatting tags may count toward it.
- One-page synopsis. About what fits on one single-spaced page. Agents who ask for a synopsis often say how long.
- Elevator pitch. One to three sentences you can say aloud in about 20 seconds.
The KDP limit is from KDP Help, Edit Book Details, last read on November 4, 2026. The other lengths are general publishing guidance.
How it counts
- Words are runs of letters or numbers. A hyphenated word such as “well-known”, a contraction such as “don’t” and a number such as “1,000” count as one, as most word processors count them.
- Characters include spaces and punctuation, and an emoji or an accented letter counts as one. The count without spaces is beside it, for forms that ask for that instead.
- Sentences and paragraphs are rough: a sentence ends at a full stop, question mark or exclamation mark, and a blank line starts a new paragraph.
