Quick answer
Short answer
A 10x12 room is 120 sq ft before waste. With 10% waste, plan around 132 sq ft, then round up to full boxes or rolls.
- Measure actual room dimensions.
- Add 5% to 15% waste depending on layout.
- Round up to full cartons and save a few pieces for repairs.
Start with square feet
Multiply length by width. A simple 10 by 12 room is 120 sq ft before closets, doorways, and waste.
Waste depends on layout
Straight plank layouts may need about 8% to 10% waste. Diagonal tile, closets, or many cuts can need more.
Box coverage decides the final order
Flooring is sold in full packages. After adding waste, divide by box coverage and round up.
