Why calculate wastage?
When ordering materials like tiles, hardwood, or carpet, it’s impossible to use 100% of the material. Cuts, corners, and broken pieces mean you always need more than the actual floor area.
The 10% Rule
For standard rooms, a 10% wastage factor is industry standard. For complex rooms with many corners or diagonal patterns, you may need up to 20%.
