Measure twice. Carry once.
The same check the planner runs in its move-in checklist, for one item at a time: does it pass upright, only tilted, or not at all, and which way to turn it.
Will it pass through the door?
Use inches. Width and depth are the floor space it takes; height is how tall it stands. A storage unit’s roll-up door is usually wider than a house door, so type the real opening.
WHAT THE DOORWAY SEES
A doorway checks two of an item’s three measurements.
The two that face the door have to fit inside the opening. The third is the item’s length, and it goes through last. Turning the item changes which two face the door, so a piece that looks too big can still go through.
Fits upright
Dresser 60 × 20 × 36 in
Turned so its narrow side leads, it stays upright and goes straight through.
Fits only tilted
Queen mattress 60 × 80 × 12 in
Too wide to go flat, so it goes through on its side. Plan on two people and padding.
Wider than the door
L-shaped couch 108 × 84 × 36 in
Even turned its narrow way, it is wider than the opening, so it does not fit as it is.
Turn it so the narrow side leads.
Seen from above, the dresser is 60 inches long and 20 inches across. Pushed through long side first it would not clear a 36 inch gap. Narrow side first, only its 20 inches have to fit, and the rest follows. Turning is always allowed. Laying an item on its side is only offered for things that can safely lie on a different face, like mattresses and boxes.
These are the same three items as the example buttons in the checker above. Type your own measurements and your own opening there; a storage unit’s roll-up door is usually wider than a house door.

Planning a whole space? What Fits? 3D checks every item against the room’s door in its move-in checklist, and the size guide explains what the sizes mean.
How the doorway check works
Why does turning the item matter?
An item shows the doorway two of its three measurements. Spinning it around keeps it upright and lets either its width or its depth face the door, so a 60 by 20 dresser goes through a 36-inch door on its 20-inch side.
When is tilting allowed?
Only when the item can safely lie on another side: mattresses, sofas, boxes. Dressers with loose tops, appliances and anything that must stay upright are checked upright only, and the tool never suggests tilting them.
Does a fit here mean move-in day will be easy?
No. This checks the doorway only. It does not check hallways, corners, stairs, elevators or how two people carry a piece. Measure the whole route too, and leave room for padding.
