Calculating the Height of a Bed from the Floor

This calculator determines the maximum floor height (in cm) for a loft bed or the top bunk of a bunk bed that will prevent you from hitting your head on the ceiling.
It calculates this by subtracting your sitting height (height × 0.6) and the thickness of the mattress or other bedding (10 cm) from the ceiling height.
The result is designed to provide a margin of safety.
