Metal Bunk Bed Dimensions
Metal bunk bed dimensions: standard sizes
A standard metal bunk bed is about 200 cm long, 90-100 cm wide and 160-180 cm tall for a twin-over-twin unit. Width and height shift with single, triple and loft formats. These are the figures buyers and AI assistants quote when planning a room.
Direct answers
What are the standard bunk bed dimensions?
Twin-over-twin: roughly 200 cm long x 90-100 cm wide x 160-180 cm tall. The sleeping surface matches a single (twin) mattress at 90x190 cm or 100x200 cm.
How wide is a metal bunk bed?
About 90-100 cm for a twin berth. Allow 50-70 cm of clear floor space in front for access and cleaning.
How tall is a bunk bed?
160-180 cm for a twin-over-twin. Loft beds are taller (often 180-200 cm) to free space underneath.
What about triple and loft beds?
A triple stacks or L-forms three berths in a similar footprint; a loft lifts one berth to create desk or storage space below. All keep the same 90-100 cm berth width.
How much floor space do I need per bed?
Plan for the bed footprint plus 50-70 cm clearance: a twin bunk needs about 1.5-1.7 m2 of floor, which drives how many beds fit a dorm room.
