  • Clearance each side — Required
  • Clearance at foot — Required
  • Clearance at head — Optional

Maximum bed footprint

Enter the measurements above to calculate maximum bed footprint.

How the calculation works

V17 calculation: maxBedWidth=max(0,roomWidth-2×sideClearance); maxBedLength=max(0,roomLength-footClearance-headClearance). The result is reported as Maximum bed footprint.

Worked example

Example: Bedroom width = 360 cm; Bedroom length = 450 cm; Clearance each side = 30 cm; Clearance at foot = 5 cm; Clearance at head = 5 cm. Result: Max Bed Length = 440 cm; Max Bed Width = 300 cm.

For what bed size fits my bedroom, the limiting result on this page is maximum bed footprint.

Direct measurement/geometry calculation. No external reference is required for the arithmetic itself; the result is derived only from the user-entered measurements and the formula stored in calculationLogicJson.
