Flooring Calculator: formula & methodology
Floor area = room length × width. Quantity to order = ceil(floor area × waste factor ÷ coverage per box).
The tool uses your entered values and explicitly labeled assumptions. Final results may be rounded for display, while intermediate arithmetic retains available numeric precision. Verify material, tax, device or platform specifications relevant to your situation.
Worked example
A 110 sq ft room, ten percent waste and 20 sq ft coverage per box requires 7 whole boxes.
Try the example above and then change values to reflect your own project or comparison.
