Precise dimensions that snap to the product edge
Line endpoints snap to the product outline as you draw, so nothing drifts out of alignment. Deterministic geometry locks in the accuracy generative AI can’t.
Upload a product photo, mark dimensions and specs in minutes, and export bilingual images sized for Alibaba, 1688 and Amazon. The precision AI can’t deliver, done in one place.

A product spec sheet is a single labeled image that lists a product's exact dimensions, materials, and specifications, so overseas buyers understand size and detail before ordering. With SizeMarker you build one from a photo in minutes — the measurements stay accurate because the geometry is deterministic, not AI-generated.

One label holds both languages at once, so exports are ready for overseas buyers without a round of translation and re-layout.
Alibaba 1000², 1688 800², AliExpress, Amazon 2000² — pick one and export, no spec-sheet lookups.
AI suggests lines and estimates dimensions to speed you up, while you keep full control of accuracy. No flashy output — just spec sheets done right and fast.
