Paste your listing copy and see live counts against Amazon's limits, including the 75-character title cap in force since July 27, 2026, the 125-character Item Highlights field, and the 250-byte backend search terms limit that Amazon counts in bytes, not characters. Flags promotional words, all-caps, banned symbols, and wasted search-term bytes. Runs in your browser.
Limits verified September 15, 2026 against Amazon's June 10, 2026 Seller Central announcement and category style guides. Media categories (books, music, video) keep the older 200-character title limit; use the toggle.
The searchable field shown under the title since July 2026: materials, use cases, comparison terms that no longer fit in 75 characters.
Five bullets. Amazon's style guides vary by category; the common guidance is under about 200 characters each and under 1,000 total so they read on a phone. Hard caps are higher and category-specific.
Counted in bytes. Plain English letters are one byte; accented characters are two or more. Over the limit and Amazon may ignore the whole field. Spaces separate terms; commas waste bytes.
Nothing you type is sent anywhere. Checks are conservative: a flag is a thing to look at, not a guarantee of suppression. Amazon's category style guide in Seller Central is the final word.
Amazon announced the cap on June 10, 2026 and began enforcing it July 27 for every category except media. Titles left over the limit are rewritten by Amazon's AI gradually; Brand Registry sellers get a 14-day review window, everyone else does not. Media categories (books, music, video, software) keep the 200-character limit. The counter also flags promotional words (best, top rated, sale, free shipping), words in all caps, and symbols Amazon disallows in titles.
The new field that carries what used to live in the title: materials, use cases, comparison terms. It is searchable and appears under the title in results and on the product page. You can only add it once the title is at or under 75 characters, which is why the two counters sit together.
Hard character limits are set per category in Amazon's style guides and are higher than anyone should use. The working rule is the first hundred characters of each bullet carry the benefit and the keyword, each bullet stays under about 200, and the five together stay under about 1,000, because that is what a shopper sees before tapping "see more."
One field, counted in bytes. Exceed it and Amazon may ignore every term you entered. The counter uses the same byte math as Amazon (UTF-8), flags commas and repeated words, and flags words already in your title, which are wasted bytes.
Replaced on the page by A+ Content for Brand Registered sellers, but still indexed and still read by AI shopping assistants. Plain text; Amazon strips most HTML.
Your category's specific style guide, gated-category rules, and whether a claim is substantiated. It counts and flags; it does not approve. Full method in the listing optimization checklist and the high-converting listing guide.
