Use room dimensions, doorway clearance, hallway turns, and product footprint to avoid costly online furniture mistakes.

Start with the final room

Measure the wall where the furniture will sit, the walking space around it, and any drawers or doors that need room to open.

Measure the delivery path

Doorways, stair turns, hallway width, and elevators matter as much as the final room footprint.

Check assembled and packaged dimensions

A product may fit after assembly but arrive in a long box that needs more delivery clearance.

Leave practical clearance

Allow extra space for hands, packaging, baseboards, rugs, and slight measurement differences.
