How the flooring calculator works
Floor area = length × width. Required packs = area × (1 + cutting allowance) ÷ coverage per pack, rounded up.
Check your measurements and assumptions
Measure each room at floor level and calculate irregular rooms as separate rectangles. Pack coverage can vary by product, so use the value on the packaging.
Review the estimate before you act
Compare this result with an independent measurement, supplier quote or institution guidance when the decision matters. Confirm that the units and assumptions match the labels above, and update the inputs when the conditions change. Keep a note of the values used so you can reproduce the estimate later. This calculator is a planning aid and does not replace professional, product-specific or local guidance.
How much extra flooring should I order?
The default 10% allowance covers many straightforward rooms, but angled layouts and complex cuts may need more.
