Estimate flooring for multiple rooms
Buying flooring means knowing the total area plus extra for cuts and mistakes. This estimator totals flooring area across rooms and adds wastage, so you buy enough for the whole job.
Why wastage is essential for flooring
Flooring is cut to fit, and the offcuts at edges and around obstacles are waste you still have to buy, so the area of the rooms alone is not enough. A wastage allowance, typically a percentage on top, covers cuts, mistakes and the spare you want for future repairs from the same batch. Totalling several rooms and adding wastage gives the real quantity to purchase, which avoids the serious problem of running out and being unable to match the batch later.

Frequently Asked Questions
Why add wastage to flooring?
Because flooring is cut to fit, and offcuts around edges and obstacles are waste you still buy. A wastage percentage covers cuts, mistakes and spare.
How much wastage should I allow?
Commonly around 10%, more for complex rooms or diagonal patterns. The calculator lets you set the percentage.
Why keep spare from the same batch?
Because flooring batches vary slightly in colour and pattern, so spare from the same batch is essential for matching future repairs.
Can it total several rooms?
Yes. It sums the area across rooms and adds wastage, giving one quantity to purchase for the whole job.
Is my data uploaded?
No. The calculation runs entirely in your browser.
