Under-bed storage

How to measure under-bed clearance — and which box height fits

Under-bed storage fails when people measure mattress height instead of the actual floor gap. The height limit comes from the lowest part of the bed frame, and that varies a lot by bed type.

What this guide helps you decide

The floor-to-frame measurement is the only number that matters when choosing under-bed storage. Divan beds, slatted frames and ottoman beds all measure differently — and centre support legs can cut the usable length in half.

how to measure different bed types

Use a tape measure from the floor up to the lowest part of the frame — not the top of the mattress and not the base of the divan.

how much clearance to leave

A box exactly equal to your measured clearance will scrape the frame every time you pull it out.

hard boxes versus soft bags at each clearance height

Rigid boxes with wheels or rope handles slide out easily and stack if clearance allows.

Measure the floor-to-frame gap correctly

Use a tape measure from the floor up to the lowest part of the frame — not the top of the mattress and not the base of the divan. On slatted frames, measure to the lowest slat. On divan beds, measure to the base fabric. Centre support legs and footboards are easy to miss but can significantly reduce the usable depth of the under-bed zone.

Fit check 2

Leave 1–2cm of clearance above the box

A box exactly equal to your measured clearance will scrape the frame every time you pull it out. Choose a box 1–2cm shorter than your measured gap. On carpet, the pile can also reduce effective clearance — measure from the top of the carpet, not the subfloor.

Fit check 3

Choose hard boxes for ease, soft bags for very low frames

Rigid boxes with wheels or rope handles slide out easily and stack if clearance allows. Fabric bags compress slightly, which helps on low frames under 15cm, and work well for bulky duvets and bedding. Bags are harder to access regularly and can lose shape over time without rigid support.

FAQ

How do I measure a divan bed for under-bed storage?

Measure from the floor to the bottom of the divan base — not to the top of the mattress. Most divan bases sit 15–25cm off the floor, but some low-profile models have as little as 5cm of clearance, which rules out rigid storage entirely.

My bed has centre support legs — what can I still use?

Centre legs divide the under-bed space into sections. Measure the length from the head or foot of the bed to the first leg, then choose boxes that fit within that zone. Two shorter boxes often work better than one long one on these frames.

What is the minimum clearance needed for under-bed storage boxes?

The lowest rigid under-bed boxes are around 15cm high. Flat-profile fabric bags can go as low as 10–12cm. For clearances under 10cm, dedicated under-bed storage is rarely practical — a flat vacuum bag may be the only option.

Can I use under-bed storage on carpet?

Yes, but thick pile reduces effective clearance and makes sliding boxes harder. On deep carpet, choose boxes with smooth base runners or large loop handles rather than small wheels, which can sink into the pile.
