Choose the room. Then check the doorway.
A room can have enough floor area and still be the wrong shape. Start with the objects that are hardest to move, then test the room, the doorway and the route separately.
Space Index planning guide · Editorial reviewMeasure the awkward pieces first
List the furniture, appliances, equipment and boxes you actually intend to store. Measure the largest pieces in the orientation you can safely move and keep them. A sofa may change shape when its legs are removed; that is useful only if you can remove them and store the sofa that way without damage.
Use packed measurements for boxes and protective covers. A photograph helps identify an item, but does not supply reliable dimensions. Keep dimensions in one unit system so a measurement in metres is not entered as feet. Our size helper converts explicitly when you change units.
Floor area does not describe the whole room
A fictional 5 × 20 ft room and a 10 × 10 ft room each have 100 square feet of nominal area. They offer different widths and depths. A long object or wide arrangement can work in one and fail in the other. Ceiling height adds a separate constraint, and advertised dimensions may be approximate.
Sketch the items that must sit on the floor before stacking boxes. Only count stacking that the contents, packaging and handling instructions allow. Leave a usable access aisle if you expect to retrieve things; do not spend the entire footprint twice by allocating the same space to both boxes and walking.
Test the entire loading route
Ask for the clear door opening rather than the door panel size. Then check loading bays, corridors, turns, stairs and lifts that sit between your vehicle and the unit. A room dimension is not evidence of a matching door opening. A wide item may fit through a door but still fail at a tight corridor turn.
Office hours, gate hours and lift availability answer different questions. If your move happens outside office hours, ask how access works and what assistance is available. Confirm any booking or loading-bay arrangements directly before committing the moving vehicle.
Use a shortlist instead of a size guarantee
The planner creates a transparent starting estimate from your inventory and chosen aisle. Compare adjacent sizes and ask the provider to confirm the actual usable room and loading route. Keep an unconfirmed doorway separate from a confirmed mismatch: the first needs a measurement; the second needs a different option.
A larger room can be worth considering when retrieval access matters, but extra area alone does not make it better value. Compare its full billing terms and the work required to reach your belongings, not just the cost per square foot.
Your checklist.
- Packed dimensions of the largest objects
- Actual room width, depth and usable height
- Clear door width and height
- Corridor turns, lift and loading constraints
- Aisle and retrieval plan
- Gate access for your moving date
Questions worth asking.
Does a 10 × 10 unit fit a whole apartment?
That label alone cannot answer it. Inventories, packing, height, usable dimensions and access differ. Measure your own items and verify the actual room.
Can I use the room width as the doorway width?
No. They are separate measurements. Leave the doorway unconfirmed until the source or provider supplies its clear opening.
