Formula and methodology
Formula: Bed area = length×width; minimum cover length = length+2×allowance; cover width = width+2×allowance.
The calculator separates mattress area from an optional rectangular allowance for bedding drop or cover planning.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Bed length — m; minimum 1.0E-6; maximum 1000
- Bed width — m; minimum 1.0E-6; maximum 1000
- Side allowance per edge — m; minimum 0; maximum 1000
Worked example
| Input | Value |
|---|---|
| Bed length | 2 |
| Bed width | 1.5 |
| Side allowance per edge | 0.2 |
Bed area = 3 m²; cover size = 2.4 m × 1.9 m.
Assumptions and limits
- Dimensions are metres and side allowance is equal on every edge.
- The bed and cover are rectangular.
- Mattress thickness, corner shaping, shrinkage, fasteners, and manufacturer sizes are not modeled.
