What KDP allows in a book description
KDP's description box accepts up to 4,000 characters, and the HTML tags count toward that limit. Only a few tags are allowed, and this formatter uses only those:
| Bold | <b> |
|---|---|
| Italic | <i> or <em> |
| Underline | <u> |
| Headings | <h4> to <h6> (not h1 to h3) |
| Paragraphs and line breaks | <p> and <br> |
| Lists | <ul>, <ol> and <li> |
Pasting from Word or Google Docs brings along hidden styling that Amazon strips or rejects. The formatter cleans it out and keeps only the formatting KDP supports. To leave an empty line between paragraphs, KDP needs an extra line break, so that's on by default.
What Amazon won't accept
KDP's rules say descriptions can't include phone numbers, email or web addresses, reviews, quotes or testimonials, requests for reviews, time-sensitive promotions, prices or availability, spoilers, emojis, or keyword lists. The formatter warns you about addresses, phone numbers and emojis, which are the easiest to slip in by accident.

Writing in Google Docs?
Pressetter typesets your Google Doc into a KDP-ready paperback PDF and a Kindle eBook, then tells you your exact page count, spine width and cover size. The check and a full watermarked preview are free.
Questions
How do I format my Amazon book description?
Write or paste your description here, use the toolbar for bold, italics, headings and lists, then copy the HTML into the Source view of KDP's description box. Only the tags KDP supports are used.
How long can a KDP book description be?
4,000 characters, and HTML tags count toward the limit. The counter here counts the HTML exactly as KDP does.
Why doesn't my description show headings?
KDP doesn't support h1, h2 or h3. Use h4, h5 or h6 instead. This formatter converts larger headings to h4 automatically.
Why are my paragraphs squashed together on Amazon?
A paragraph tag only starts a new line on Amazon. To get a blank line between paragraphs, KDP needs an extra line break. Keep “Blank line between paragraphs” checked.
