What is a furniture spec diagram?

A furniture spec diagram is a labeled product image showing a piece's exact dimensions — width, depth, height, seat height, and packed size — along with materials and weight capacity, so buyers can confirm it fits their space before ordering. With SizeMarker you build one from a photo in minutes; the measurements stay accurate because the geometry is deterministic, not AI-estimated.

Assembled and packed sizes in one image

Mark overall width, depth, and height plus the carton size buyers need for shipping and doorways. Endpoints snap to the furniture edge so nothing drifts.

Materials and weight capacity, labeled

Call out frame material, fabric, load rating, and seat height with bilingual labels — the details that decide a furniture order.

Zoom callouts for joints and finishes

Highlight a dovetail joint, caster, or upholstery seam so buyers judge quality without asking for more photos.

Export to Alibaba, Amazon and Wayfair sizes

Pick a platform main-image size and export — no spec lookups, no re-cropping.
