What Size Bunk Bed Do You Need for a Small Bedroom?

For most small UK bedrooms, a standard single bunk bed taking two 90 by 190cm mattresses is the right size, but very compact rooms and low ceilings can call for something smaller. In this guide we explain the common bunk bed sizes, from standard and small single bunks to short cabin lengths and triple sleepers, and show how the frame adds to the mattress dimensions. We walk through measuring floor area, choosing the right wall, marking out the footprint with masking tape and leaving enough space to climb and make the beds. Ceiling height gets particular attention, since headroom on the top bunk is the measurement most often forgotten. You will also find safety advice, ideas for storage and vertical space, alternatives such as high sleepers and trundles, and a quick checklist to run through before ordering, so the bunk feels at home in the room rather than squeezed in....
