Always buy extra for cuts, replacements, and future repairs. Round up to the nearest box or bundle at the store. Diagonal or herringbone patterns typically require 15–20% waste.
Flooring Calculation with Waste
Total sq ft = room sq ft × (1 + waste%). Example: 200 sq ft room with 10% waste = 200 × 1.10 = 220 sq ft to purchase.
