Amazon Title Character Limits by Category, and What Happens at 80 Characters on Mobile

Why "by category" used to be the right question

Some of the category variation was genuinely functional rather than arbitrary — apparel and variation-heavy categories tended to carry longer allowances because size, colour and material attributes needed to be spelled out per listing, while simpler single-SKU categories often ran shorter. That functional logic doesn't disappear under the new rule; it just moves into Item Highlights instead of the title, which is a genuine change in where that information lives, not just a shorter version of the same title.

Until the July 2026 change, asking for title limits "by category" was the correct framing — different product categories genuinely carried different character allowances, commonly cited anywhere from 150 to 250 characters depending on the specific category's style guide. A seller managing SKUs across several categories legitimately needed to check each one separately, because a limit that worked in one category could silently fail or get flagged in another.

That's the reason so much still-circulating content states a title limit "varies by category, typically 150-200 characters" — it was true when it was written, and a lot of it hasn't been updated since.

What actually changed on July 27, 2026

It's worth being specific about the scope of "universal" here — the 75-character figure applies as one number across categories, but Amazon has not published every fine-grained exception that might still exist below that headline rule. Media exclusion is confirmed directly. Beyond that, the honest position is that the category-specific patchwork sellers used to navigate has been replaced by a much simpler default, not that every conceivable edge case has been eliminated.

Amazon's own Seller Central announcement states titles in all categories except media are now capped at 75 characters, spaces included — one universal limit replacing the patchwork of category-specific ones. The category-by-category system genuinely existed; it has now been collapsed into a single rule for the overwhelming majority of the catalogue, with media categories carved out as the one remaining exception.

This means any content, tool or internal style guide still built around "check your category's specific limit, usually 150-200 characters" is describing a system that no longer applies to most sellers. The correct check as of this change is simpler, not more granular: 75 characters, unless the listing is in a media category.

What actually happens at 80 characters, on mobile and beyond

This distinction is worth holding onto precisely: "truncation" and "non-compliance" describe two different mechanisms that happen to produce a similar-looking result — a title that doesn't fully display. The old mechanism was cosmetic and reversible depending on device; the new one is a field-level rule enforced the same way on every device, with a formal review process attached to it.

Under the new 75-character rule, a title running 80 characters is five over the limit and falls into Amazon's non-compliance process — flagged for an AI-generated recommendation, with the brand owner given 14 days to review, modify or approve the change before Amazon applies it automatically. It's worth being precise here: this isn't a soft mobile display truncation the way older, longer titles used to get visually cut off mid-word on a small screen — it's a hard field limit enforced at the account level now.

The older, more familiar version of "80 characters on mobile" — titles under the old, longer limits getting visually truncated with an ellipsis around that length on a phone screen — is arguably part of why Amazon set the new field limit where it did: 75 characters lands close to what a mobile shopper could reliably see anyway under the old system, so the new rule brings the actual field limit in line with what mobile display already imposed in practice.

A worked comparison: the same title at three different eras

Treat "three eras" literally: pre-limit sellers who padded titles with as many keywords as the field allowed, the category-tiered era that ran roughly 150-250 characters depending on category, and the current single 75-character rule. Each era's "correct" title for the same product looks different, which is exactly why so much still-published advice conflicts — it was written for a different era's rule and never updated.

A supplement listing's title under an old 200-character category limit: "Brand Name Premium Vitamin D3 5000 IU with K2 MK-7, High Potency Supplement for Bone Health and Immune Support, Non-GMO Gluten Free Soy Free, 180 Softgels 6 Month Supply." That title, viewed on an older mobile layout, would have visually truncated somewhere around 75-85 characters regardless of the account's field limit — a shopper on a phone was already seeing roughly "Brand Name Premium Vitamin D3 5000 IU with K2 MK-7, High Potency Supp..." and nothing past it.

Under the current 75-character field limit, that same title has to be rebuilt rather than cut: "Brand Name Vitamin D3 5000 IU + K2, 180 Softgels, Non-GMO." What's notable is how close this lands to what the phone was already showing under the old system — the field limit essentially caught up to the display limit that had been the practical constraint on mobile for years.

The mistake to watch for right now

The specific, common mistake in this transition period is a seller or an outside tool checking an old, cached "title limits by category" reference and concluding their 190-character title is fine because it fits under an old 200-character category figure. That reference is now stale for any non-media category — the check that matters is the current 75-character field limit, not a category table that predates the July 2026 change.

Third-party listing tools and templates carry the same risk if they haven't been updated — a bulk upload template with a 200-character title column, still in use out of habit, will generate titles that need immediate rework the moment they're live. Checking any external tool's assumed title length against the current 75-character rule is worth doing once, directly, rather than trusting the tool's own defaults.

Where this leaves a multi-category catalogue

These come from Full Circle, a full-service Amazon management company with $500M+ in managed revenue across 100+ brands. Dr. CRO's versioned title and Item Highlights workflow is built against the current 75/125 split rather than a per-category reference table, precisely because that table stopped being the operative rule in July 2026 — a catalogue-wide check against one current limit is both simpler and more reliable than maintaining category-specific figures that are now mostly retired.
