About this tool

Amazon KDP enforces a 200-character limit on titles and subtitles. This title length checker counts characters in real time, previews how your listing might look, and flags when you approach the limit — so your metadata is accepted on first upload.

Planning tools and long-form structure

Novels fail when structure is improvised scene by scene. Beat sheets, chapter planners, and blurb builders help you decide pacing and reader promises before you spend tokens on prose. Pair these tools with an outline in Entangled Text so generation follows a spine.

  5. Copy the final title/subtitle to KDP.

Tips for fiction authors

  • Keep your main title short and memorable — under 50 characters is ideal. Use the subtitle for searchable keywords.
  • Amazon can reject titles with excessive punctuation, all caps, or promotional language like "bestseller" or "award-winning."
  • Series titles should follow a consistent format: "Series Name Book 1: Individual Title" helps readers find the next installment.
  • Test your title at small sizes. It must be legible as a thumbnail on Amazon search results.

Should I stuff keywords in my title?
