# KDP title and description rules

Length limits and what KDP does not allow in your title, subtitle and description.

## Title and subtitle

- Together they must stay under 200 characters.
- They must match the title on the cover.
- No keyword lists, no claims such as "bestseller", no unrelated author names.

## Description

The description is the text on your product page. KDP does not allow:

- Contact details, web addresses and email addresses.
- Reviews, quotes and requests for ratings.
- Prices and time-limited offers.
- Claims about sales rank.

Write what is in the book, who it is for and why they will enjoy it. Plain short paragraphs read best on a phone.

> kdpbookai checks your listing for web addresses, prices, rank claims and review requests before you download.
