Size in the Product Title: What 75 Characters Changed

Size in the product title stopped being a free decision on 27 July 2026. That is the day Amazon began capping product titles at 75 characters, and a seller who was spending 48 of them on "72 Inches Wide x 36 Inches Deep x 30 Inches High" was suddenly left with 27 characters for the brand, the product and everything else.

The instinct is to delete the size. That is usually the wrong cut. The right cut is the wording of the size — and then a decision about which surface actually carries the number, because a title has never been where a buyer verifies a dimension anyway.

Title limits and size rules: five channels at a glance

Two things fall out of that table immediately. First, there is no single title that is right everywhere — an 80-character eBay title cannot survive Amazon, and a 75-character Amazon title wastes half of a Google Shopping feed. Second, the two platforms with the most room, Google and Walmart, are the two that explicitly ask for size in the product title. Cutting it globally because Amazon got shorter is an overcorrection that costs you on the channels that never changed.

What Amazon's 75 characters actually changed

Amazon's own announcement, posted in the Seller Central forums, set the change for 27 July 2026: titles in every category except media must be 75 characters or fewer, including spaces. Alongside it came item highlights, a new field worth 125 characters. Together that is a 200-character content budget split 75/125, where before the title carried the whole load.

Three consequences worth planning around:

• Non-compliant titles get rewritten for you. Listings still over the limit are revised by Amazon's AI. Brand-registered sellers get a 14-day review window; the rest largely find out after the fact. A title you did not write is a title nobody optimised for your buyer.
• Item highlights is searchable, and it sits next to the title. It is not a junk drawer. Materials, compatibility and use cases were named as the intended content — which is exactly where an expanded dimension string belongs once the title is full.
• The 200-character budget is not the old 200-character title. Order matters more now. The first 75 characters are the ones the buyer reads before deciding to keep scrolling.

The practical read: this was not an instruction to hide size. It was an instruction to stop spelling it out in prose.

When size in the product title earns its characters

Take a position on this per category rather than per platform. Three buckets:

Always in the title. Size is the product identity — the buyer is not choosing between products, they are choosing between sizes. Apparel and footwear, mattresses and bed frames, rugs, tyres, pipe and fitting sizes, TV mounts, storage volumes. Google says outright to put the variant distinguishers in the title, because a feed with five sizes and one title is five listings competing to look identical.

Compress and keep. Bulky goods where fit is the buyer's first question but not the variant axis: furniture, appliances, cabinets, planters, pet crates. One compressed dimension string earns its space here. Everything past that string does not.

Leave it out. Multi-dimension full specs, tolerances, packaging or shipping dimensions, assembled versus folded pairs, and anything with a unit spelled out twice. These belong in attributes, in the spec table and on the image. A title carrying two sets of dimensions reads as noise, and on a 75-character cap it is noise that evicts the words buyers actually search.

The size wording that wastes the most characters

Same fact, fewer characters. These are the six rewrites that recover the most room on a capped title:

Four rules make those rewrites safe rather than cryptic:

1. Order the dimensions the way your category reads them and never mix the order across a catalogue. If your listings disagree with each other about whether the first number is width or length, the compression has bought you characters and cost you trust.
2. One unit system in the title, both in the attributes. Pick the buyer's system, not the factory's. Which one to lead with is genuinely category-dependent, and the trade-off is laid out in product dimensions in cm or inches.
3. Drop the word "Dimensions" and drop "Size:". They tell the reader nothing that the numbers do not.
4. Never compress into ambiguity. "72x36" without a unit is not a size, it is a guess. Eleven characters that mean something beat six that do not.

Where the dimensions go when the title is full

A title states a number. It has never let anyone check one. That is the split worth internalising, because it decides what you build next.

• Structured fields first. Google wants size in the size attribute as well as the title; Amazon has 125 characters of item highlights; Walmart has attribute fields for the same values. Feeds are also what AI shopping agents read, and an agent parsing an attribute is far more reliable than one parsing your adjectives — the fields that matter, and the ones almost nobody fills in, are covered in product dimensions structured data.
• The spec table second. Buyers who want the full dimension set go looking for a table, not a longer title. Where that table belongs versus what belongs on the image is the whole argument in how to display product specifications.
• The image last, and it matters most. This is the only surface where a buyer can verify the number instead of reading it. A dimension drawn onto the product photo — arrows on the real edges, the measurement beside them — answers the size question in the two seconds before someone scrolls away.

That last one is where the tooling choice actually shows. Marking sizes on an image is a measurement job, not a design job: the arrow has to snap to the product's true edge and the label has to carry the measured value, then export at each platform's image spec. An AI image generator will cheerfully place a confident "72 in" on a render it never measured, and a plausible-looking wrong number on a listing is worse than no number at all — it converts, then it comes back. If you want the size of that downside in currency rather than in principle, run your own numbers through the return cost calculator.

A 10-minute title audit for one SKU

• Count the characters — actually count them, do not eyeball the field
• Amazon title is 75 characters or fewer including spaces
• Anything cut from the Amazon title has been moved into item highlights, not deleted
• Size appears in the title on every channel where size is the variant axis
• The dimension string uses one unit system and one dimension order
• The words "Dimensions", "Size:", "Measures" and any doubled unit are gone
• Every compressed dimension still carries its unit
• The size attribute is populated in the feed, not only in the title
• The full dimension set exists in a spec table on the page
• The main image or a gallery image shows the dimensions, so the number can be checked and not just read
• The same dimension appears identically in title, attribute, table and image — one disagreement is a returns claim waiting to happen

That last box is the one that gets skipped and the one buyers punish. A title that says 72 inches, an attribute that says 183 cm and an image with no arrow at all is three sources of truth, and the buyer will pick whichever one turns out to be wrong.

FAQ

Should I put dimensions in the product title?

Size in the product title earns its characters when size is how buyers choose between your variants — apparel, mattresses, rugs, fittings, mounts — and in compressed form for bulky goods where fit is the buyer's first question. No for the full dimension set, tolerances or packaging sizes. Google explicitly asks for variant details such as size in the title and in the size attribute; Amazon's 75-character cap means the same information has to arrive in far fewer characters.

Does Amazon's 75-character title limit include spaces?

Yes. The limit is 75 characters including spaces, and it applies to every category except media. Item highlights adds a separate 125 characters, so the total content budget is 200 characters split across two fields.

What happens if my Amazon title is longer than 75 characters?

Amazon rewrites it. Listings above the limit after 27 July 2026 are revised by Amazon's AI titling systems; brand-registered sellers get a 14-day window to review, modify or approve the suggestion, and everyone else effectively inherits the result. Writing your own compliant title is the only way to control which words survive.

Does putting size in the title help search ranking?

It helps matching more than ranking. A shopper searching "60x80 bed frame" or "24 inch round table" is using a size as the query, and a title carrying that string in the format people type is what gets matched. Spelling the same size out as "Sixty Inches by Eighty Inches" matches nothing anybody types.

Where should the dimensions go if the title has no room left?

Into three places at once: the structured size attribute in your feed, the spec table on the page, and the image itself. The image is the one buyers actually trust, because it is the only place where a dimension is shown against the product rather than asserted next to it. Producing that reliably means measuring on the image — snapping the arrow to the real product edge, labelling the measured value, then exporting at each marketplace's required image size — rather than typing a number over a photo and hoping it is right.
