Quick answers
What does this renovation calculator estimate?
It estimates material quantities for tiles, paint, and flooring using room dimensions, product size, and a waste percentage.
What should I set for tile/flooring wastage?
Waste depends on cutting and layout. A common starting point is 8–10% for straight layouts; use a higher value for diagonal patterns or complex rooms.
How is paint quantity calculated?
Paint is estimated from wall area (height × total wall length), minus doors/windows, multiplied by number of coats, then divided by coverage (m² per liter).
