The dimensions an AI assistant can't read

We read real home and garden listings, checking one thing: could an AI shopping assistant confidently tell a buyer whether a product would fit their space?

In homewares, the deciding question is almost always the same: will it fit? Will the sofa fit the room, fit through the doorway, suit the space it's meant for. A beautiful piece a buyer isn't sure will fit is a beautiful piece they don't risk buying.

When the measurement lives only in a diagram, it is on the page for a human and absent for an assistant.

A neat dimensions diagram — width, depth and height laid out cleanly — is good human-facing practice. The trouble is that a diagram is a picture. An AI assistant reads a product page as text, and to it, a dimensions image is indistinguishable from no dimensions at all. The information exists; the assistant just can't see it.

For larger items, a second measurement compounds it. Packaged and doorway dimensions answer a question buyers cannot otherwise resolve — whether the item will physically reach the room. Where they are unstated, neither the buyer wondering if a wardrobe will make it up the stairs, nor an assistant trying to recommend it, can determine it. So the assistant hedges, or points the buyer to a listing that states the numbers plainly.

Why this happens

Good human-facing design can hide the deciding fact

This gap is unusual because it comes from doing something right. A clean dimensions diagram is genuinely good design for a human shopper. But the same choice that helps a person can hide the deciding fact from an assistant — and the more a catalogue leans on diagrams and photos to carry its measurements, the less an assistant can actually work with.

That's why the fix is rarely “add more.” It's “put the numbers in words as well as the picture.” The listing keeps its polish for humans and becomes readable to the assistant that increasingly decides what a shopper sees.

Note the limit of what an assistant can do here. It cannot measure a room, and it cannot infer a doorway. It can only repeat what the listing states — which is why an unstated centimetre is, to it, an unknown one.
