How the furniture volume estimate works
The calculator assigns a planning volume to common furniture types, adds 3.1 cubic feet for each packed box, adjusts a limited set of disassembled pieces, then applies the loading buffer you select.
(furniture item counts × item factors + boxes × 3.1) × loading bufferThe factors are deliberately rounded planning values, not manufacturer dimensions or a claim that every piece in a category has the same size.
Measure the pieces that can control the move
Sectionals, armoires, safes, exercise machines, workbenches, antiques, and unusually deep appliances should be measured directly. Multiply outside length, width, and height in inches, then divide by 1,728 to convert the rectangular envelope to cubic feet.
Volume cannot prove that an item fits
A sofa can have modest volume and still fail at a stair turn. Check the full route: doors, hallways, elevator openings, railings, truck ramp, and destination-room approach. The apartment moving checklist provides a route-measurement sequence.
Use the result as a bridge
Take the combined cubic-foot result to the truck size calculator for a second planning view, or use the storage unit calculator when the inventory needs aisles and repeated access.
Complete the inventory before booking
Use the room-by-room moving inventory to account for closets, garages, and unusually large pieces before relying on a volume range. If the furniture will be boxed or protected separately, the packing supplies calculator converts the expected carton count and specialty items into a practical materials list.
