What size bed fits my room? US and UK planning guide

There is no universal minimum room size for a bed. Compare US and UK mattress dimensions, then add the modelled side and foot clearances; bed-frame overhang, doors and other furniture can change the layout.

US bed sizes
Compare nominal US Full, Queen, and King mattress widths and lengths. US sizes differ from UK and other markets.
UK bed sizes
Compare UK Standard Double, Standard King, and 180 × 200 cm mattress references. Bed-size names and dimensions are market-specific.
King mattress room-space estimates: US vs UK
Compare clear-space plans for US King and UK Standard King mattresses. These are recommendations, not building-code minimums; frame and furniture dimensions vary.
US Queen mattress: clear-space planning estimate
Estimate a mattress-only clear-space rectangle for a nominal US Queen using a sourced side allowance and an explicit FitWise foot allowance. This is not a complete room layout or building-code minimum.
What bed fits in 10x10 room
Compare market-specific mattress footprints against the 10 × 10 ft reference bedroom (US). Results distinguish mattress-only physical fit from recommended side/foot clearances.
What bed fits in 10x12 room
Compare market-specific mattress footprints against the 10 × 12 ft reference bedroom (US). Results distinguish mattress-only physical fit from recommended side/foot clearances.
US King vs Queen: compare mattress and room-space dimensions
Compare nominal US King and Queen mattress footprints and recommended clear-space rectangles. Estimates exclude frames, furniture and circulation; they are not legal minimums.
Wardrobe door swing: measured PAX/GRIMO example
Use one measured US-market PAX/GRIMO door leaf to calculate its 90-degree swing envelope and compare it with the actual bed and room.
Bed-to-dresser clearance: measured drawer-extension example
Model a sourced bed frame and dresser drawer extension as a collision envelope; standing space remains user-selected, not a universal minimum.
US King bed with two bedside tables: footprint example
Add nominal US King mattress width to two measured bedside-table widths. The result is an object footprint, not a room-size recommendation.
US Queen bed with two bedside tables: footprint example
Add nominal US Queen mattress width to two measured bedside-table widths. The result is an object footprint, not a room-size recommendation.
