Amazon FBA character limits at a glance

  • Product Title — 200 characters (some categories cap at 80 or 150)
  • Bullet Points — 500 characters each, five bullets total
  • Product Description — 2,000 characters including HTML tags
  • Backend Search Terms — under 250 bytes, which is not the same as characters

Exceed a limit and Amazon may truncate the field, suppress the listing from search, or reject the upload entirely. The bars above turn amber at 80% and red when you go over, so you can see trouble coming before you paste into Seller Central.

Why banned word detection matters

Amazon prohibits promotional and unverifiable claims in listing copy. Phrases like "best seller," "guaranteed," "free shipping," and health claims such as "cures" or "FDA approved" can get a listing suppressed. The compliance check flags these instantly so you can rewrite before publishing.

Your listing copy stays private

Product listings are competitive assets. Everything here runs in your browser, so your titles, bullets, and descriptions are never uploaded to any server.
