How to Calculate Hardwood Flooring
Formula
Flooring Needed = Room Area × (1 + Waste Factor)
Measure the room length and width to get square footage. Add 10% waste for standard straight installations and 15% for diagonal or herringbone patterns. Hardwood flooring is typically sold in boxes of 18-25 sq ft.
Example Calculation
A room 16 ft by 14 ft with 10% waste at $5.00/sq ft.
- 01Floor area = 16 × 14 = 224 sq ft
- 02With 10% waste = 224 × 1.10 = 246.4 sq ft
- 03Boxes (20 sq ft each) = ceil(246.4 / 20) = 13 boxes
- 04Material cost = 246.4 × $5.00 = $1,232.00
