Amazon KDP lets you use real HTML in your book description — bold, italics, bullet lists, headers, line breaks. Most authors either don’t know this or use the wrong tags and end up with broken code showing on their product page. This guide gives you every tag that works, how to use it, and copy-paste templates ready to go.
Your book’s description is doing two jobs at once. It needs to sell your reader on the idea of the book — and it needs to do that in a format that is easy to read on a screen. Plain walls of text almost never work. The good news is that Amazon’s KDP description field accepts real HTML markup, which means you have full control over how your description is displayed on the product page.
The bad news is that KDP only supports a specific subset of HTML tags. Use an unsupported tag and you will either see it stripped entirely, or worse, see raw angle brackets and tag names showing up in your description where formatted text should be. This guide tells you exactly which tags work, which do not, and how to build a description that looks intentional and professional.
Most readers do not read a book description — they scan it. Bold headlines create scanning anchors. Bullet lists let readers check off whether the book delivers what they need. Line breaks prevent the eye from getting lost in dense paragraphs.
There is also a practical SEO element. Amazon’s A9 algorithm weights conversion rate as a ranking signal. A better-formatted description that converts more visitors into buyers tells Amazon’s algorithm your book is relevant — which nudges you higher in search results over time.
Go to your KDP dashboard → select your book → click Edit → navigate to the Book Details page → find the Description field. Paste your HTML directly into this text area. Do not paste from Microsoft Word — always use a plain text editor like Notepad or VS Code.
Bold is your most powerful formatting tool in a KDP description. Use it for the key hook in your opening line, for scannable sub-labels, and to highlight the most compelling promise your book makes. Italic works well for book titles, brief emotional emphasis, and award or credential mentions.
Both <b> and <strong> render identically in KDP descriptions.

Both <em> and <i> render as italics in KDP. Use sparingly — for titles, credentials, or a single phrase that deserves quiet emphasis.

</ol>Use emoji directly in your text: ✅, ➤, ★, •, ◆. These render across all devices and add visual interest without requiring any markup. Combine them with <br> tags for clean spacing between items.
In practice, <h3> and <h4> are the most useful — large enough to stand out without overwhelming. <h1> renders very large and can look out of proportion. Use headings to create sections: a hook, a “what’s inside” section, an author credentials section, and a call to action.

Description formatting is just one piece of the sales puzzle. This guide covers the full royalty optimization strategy — pricing tiers, KDP Select vs. wide publishing, A+ content, and building passive income across a backlist.
KDP enforces a 4,000 character maximum on the description field. This includes every HTML tag you use — opening tags, closing tags, and attributes all count. A typical description with solid HTML formatting will use 350–600 characters on markup alone.
Write your description in a plain text editor — Notepad on Windows or TextEdit in plain text mode on Mac. Never draft in Microsoft Word or Google Docs — both add invisible Unicode characters and “smart quotes” that can appear as strange symbols on the Amazon product page.
Generate your HTML, preview it Amazon-style, and check your character count — all on this page. No extra tabs needed.
Fill in the fields below and the tool instantly builds a properly formatted HTML description — ready to copy and paste directly into your KDP dashboard. No coding needed.
