Under-Bed Measurement Worksheet

Print this, take it to the bed, and fill it in before you buy anything. Everything here needs a tape measure and a piece of cardboard.

1. Measure four points, not one

The side rail is usually the most generous point in the whole opening, which is why measuring there is how people end up with storage that stops halfway.

Corner legsA foot or bracket may sit lower than the rail.

Smallest of the four corners:

Centre supportFull and queen frames often carry a centre leg or cross member you cannot see from the side.

Measurement: or tick if none:

Entry sideThe exact point the container would cross going in.

Measurement:

Far sideWhere the container has to finish its travel.

Measurement:

Write the smallest of the four here. This, not the average, is your clearance:

2. Work out the height budget

Your clearance is the ceiling. Four things spend it before the container ever arrives. Subtract each one.

What spends it	How to measure it	Subtract
Carpet compression	Press a loaded container onto the pile, measure again at that height
Lid stack	Measure the container closed and loaded, never open and empty
Handle rise	Measure across the handle, not across the lid
Margin you are willing to lose	Your call. Leave something.
Height budget = clearance minus the above

Shop against the height budget, not against the number printed on the bed frame.

3. Test the pull path before you buy

Height and travel fail separately. A container can clear the gap and still be useless.

Cut cardboard to the container's footprintLength and width, roughly. It costs nothing and it answers the question.

Push it in and pull it out from the side you would really useWith the wardrobe door and the nightstand in their normal positions.

Clear floor available on the pull side:

Push it back inThis is the direction people forget to test, and the one that fails more often.

If the clear floor is shorter than the container is deep, the storage only works when the room is rearranged first, which means it does not work.

4. Decide

Verdict	When
Keep	Closed loaded height fits the budget, and one full pull completes without moving other furniture
Move	The budget rules out the lid, or the pull path is shorter than the container is deep
Skip	Any of your four measurements is uncertain. Measure again rather than buying to find out.
