How long can a KDP title and subtitle be?

Title plus subtitle must be under 200 characters combined. The checker counts both fields together, including spaces, and treats 199 as the ceiling.

Does the subtitle count toward the 200 characters?

Yes. KDP sets the limit for title and subtitle together, so a long subtitle leaves less room for the title.

Can I put "bestselling" or "free" in my title?

No. KDP does not allow sales-rank claims such as "#1 bestseller" or promotional words such as "free" in the title or subtitle.

Does the title have to match the cover?

Yes. The title you enter must match the title on the cover exactly. The checker cannot see your cover, so compare them yourself.

KDP needs title plus subtitle to stay under 200 characters combined, with no HTML, promotional words, sales-rank claims or unauthorized trademarks, and the title must match the cover. Type both fields to see the count, the characters left and anything KDP is likely to reject.

Characters left (of 199): -
Title: -
Subtitle: -

How the count works

Characters used = title length + subtitle length, after trimming spaces at each end. Characters left = 199 - characters used.

Example: "The Quiet Garden" (16 characters) with the subtitle "A Novel of Second Chances" (25 characters) uses 41 characters and leaves 158.

What it flags

Over the limit, HTML tags, placeholder titles such as "Untitled", and fields that are only punctuation.
Sales-rank claims ("bestselling", "#1") and promotional words ("free", "on sale").
Amazon names such as Kindle or Audible, and generic words repeated to stuff keywords.
A title over 60 characters: allowed, but Amazon notes shoppers tend to skim past long titles.
