From a single product photo, produce a precise spec diagram, product visuals, a breakdown diagram and a 3D model, then bring them together in one product card ready to send to buyers.
Customers scroll past plain product photos. They can't tell the actual size, can't read the specs that matter, and B2B buyers end up messaging back and forth just to confirm dimensions.
The fix? Put the details on the product itself. SizeMarker marks precise dimensions and specs on your photo, adds visuals, a breakdown and a 3D model, and puts them all on one product card you can send to any buyer.
Start with the photo you already have. Each output stands on its own — and all of them fit on one product card.
Dimension lines snap to the real outline; spec labels in two languages; export at marketplace main-image sizes.
Swap the background, place the product in a scene, fix details — the product itself stays unchanged.
Parts, materials and structure laid out on one sheet. You write the facts; the layout is done for you.
One photo becomes a rotatable model that opens in any browser — no app, no plugin.
One link per SKU with all of the above, plus specs and contact. Send it on WhatsApp, WeChat or at a trade show.
Thirteen annotation tools. Dimension endpoints snap to the product outline, so every number on the image is one you measured — the part of product content that has to be right.

Structure, parts and materials on one readable sheet.
A rotatable model from a single photo.

From furniture and industrial equipment to building materials — any product where size decides the sale.

A product card is a public page for one product: your spec diagram, visuals, breakdown, 3D model, parameter table and contact details in one link. Anyone with the link, QR code or poster can open it on a phone — no app, no login. Free accounts can keep one card published; Pro has no limit. Unpublish it and the link stops working immediately.
Dimensions and spec labels are always placed on the real photo, and dimension endpoints snap to the product outline — every number is one you measured. Product visuals, breakdown layouts and 3D models are generated from your photo, but they never carry a size claim, and the facts (materials, parameters, structure) are yours to write. Nothing is invented for you.
Yes. Every infographic tool offers full customization — colors, fonts, sizes, and animations. Save custom presets as templates for consistent branding across all your product content.
No. Everything runs in the browser on macOS and Windows — annotation, visuals, breakdowns, 3D and product cards. Exports download as image or video files, and a product card is a plain web page any buyer can open on a phone.
SizeMarker is focused on spec sheets for selling and closing deals — not engineering drafting. It doesn't import CAD/DXF or implement GD&T tolerance systems. For toleranced engineering drawings use dedicated CAD; SizeMarker makes the customer-facing dimension and spec sheets fast and accurate.
Free includes all 13 annotation tools, 70+ preset styles, full-resolution image export (with a watermark), 30 credits and one published product card. Pro adds watermark-free image and video export, batch export to marketplace sizes (Amazon, Alibaba, TikTok, Instagram), your own templates and brand presets, 2 GB cloud sync, unlimited product cards and 1,500 credits every month for visuals, breakdowns and 3D.
Mark the sizes, add the visuals, send one link — and let buyers order with confidence.
