Flooring Calculator
Calculate exactly how much flooring to order for any room, including waste for cuts and difficult installation areas.
How It Works
Calculates room area (length × width), applies waste factor, and shows results in sq ft, sq yds, and sq meters.
Formula
Area = L × W
Order Qty = Area × (1 + Waste%/100)
Example
15×12 ft room = 180 sq ft. 10% waste: 198 sq ft (22 sq yds)
When to Use This Calculator
Use before purchasing any flooring material to ensure you buy enough without major overages.
Common Mistakes to Avoid
- Buying the exact calculated amount — you will likely run short.
- Confusing sq yards with sq feet — verify pricing units.
- Forgetting closets — measure all spaces and add together.
