About this calculator
Generic flooring projects need a different estimator than tile because boards and laminates are usually purchased as pieces packed in boxes, not individual tiles or square-meter rolls.
A good flooring calculator should show both the theoretical board count and the actual box count so the result matches how the material is purchased.
Frequently asked questions
Why do flooring boards need a waste allowance?
Because edge cuts, damage, and layout alignment increase the quantity needed beyond the pure floor-area math.
Is this different from the tile calculator?
Yes. This page is geared toward plank or board-style flooring where pack size and board count are the key purchase units.
Should I order spare boards too?
Many installers do, especially when matching future repairs might be difficult, but that choice depends on your project and product availability.
