Amazon Book Title Character Counter

Track the 200-character combined title and subtitle limit Amazon KDP enforces. Free, no signup, runs in your browser.

Last updated: May 5, 2026

The Amazon Book Title Character Counter is a free KDP tool that tracks the combined 200-character limit Amazon enforces on your title plus subtitle. It counts spaces and punctuation, flags banned phrases like "bestseller" and "free" that get books rejected, and shows a live preview of how the listing displays with the colon Amazon auto-inserts between fields. Everything runs in your browser.

Your title and subtitle

What are the KDP metadata field limits?

Amazon enforces hard character limits on every KDP metadata field. The title and subtitle share a 200-character budget. The book description has its own 4,000-character budget that includes HTML tags. Authors who paste long subtitles, format declarations, or promotional language hit metadata review delays of two to ten days. The reference below covers every field this tool and its sibling tools track.

Field	Limit	Notes
Title + Subtitle	200 characters (combined)	Spaces and punctuation count. Title is required, subtitle is optional.
Book description	4,000 characters	HTML tags count toward the limit. Only a small tag allowlist is rendered.
Author / Contributor	50 characters per name	Pen names allowed. The name displayed on the cover and in metadata must match.
Keywords (7 slots)	50 characters per slot	Long-tail phrases beat single words. Amazon ignores duplicate words across slots.
Categories	3 BISAC categories	Picked from the BISAC list. Amazon may add more after publication.
Series name	120 characters	Optional. Series number is a separate numeric field.

Why the 200-character limit matters: Amazon counts every character in your title plus your subtitle, including spaces and punctuation. The colon and space Amazon auto-inserts between fields on the listing page do not count, but they affect how the title displays. Most readers see the first 50 to 70 characters on mobile search results before truncation, so the most important words belong at the start of the title, not buried in the subtitle. Authors who pad subtitles with trope keywords often lose 30 to 80 characters of their actual hook to truncation, and Amazon flags subtitles that read as keyword stuffing rather than context.

Frequently asked questions

What is the character limit for an Amazon book title?: Amazon KDP allows up to 200 characters for the title and subtitle combined. The limit counts spaces and punctuation, but does not count the colon Amazon auto-inserts between title and subtitle on the listing page. Most books use far less, but the cap is firm. KDP rejects submissions over 200 characters at the metadata review stage.
Does the 200-character limit include the subtitle?: Yes. The 200-character cap is the title and subtitle combined, not 200 characters per field. If your title is 60 characters, your subtitle can be up to 140. The auto-inserted colon and space between title and subtitle on the Amazon page are presentation only and do not count against your stored 200 characters.
What words should I avoid in my book title or subtitle?: Amazon rejects titles containing promotional language ("bestseller", "free", "on sale", "discount"), Amazon brand names ("Amazon", "Kindle", "KDP"), format declarations ("Kindle edition", "ebook edition", "paperback edition"), or pricing claims ("% off", "limited time"). The tool above flags every banned phrase as you type so you catch them before submitting metadata.
Can I have a subtitle without a title?: No. The title is the only required field. Subtitle is optional. Most romance, thriller, and fantasy authors use the subtitle to surface a high-search trope or series tag, for example "The Salt Cure: A Small-Town Romance" or "Dawn Bringer: Book One of the Ember Cycle". Use the subtitle for context, not for repeating title keywords.
How does Amazon display my title and subtitle on the book page?: Amazon concatenates title and subtitle with a colon and space in between, like "The Salt Cure: A Small-Town Romance". Mobile listings often truncate after about 70 characters, with the rest accessible via a "show more" expander. Search results truncate even more aggressively, sometimes at 50 characters. The most important words belong in the first 50 characters of the title.
Does this tool send my title to a server?: No. The Amazon Book Title Character Counter runs entirely in your browser. Your title, subtitle, and any draft metadata never leave your device. There is no signup, no account, and nothing to install. Close the tab and the data is gone.
