Rectangular Room:
Area = Length × Width
L-Shaped Room:
Area = (L1 × W1) + (L2 × W2)
Total with Waste:
Total Area × (1 + Waste %)
Unit Conversions:
1 sq yard = 9 sq feet
1 sq meter = 10.764 sq feet
1 sq foot = 144 sq inches
- Measure twice: Always double-check your measurements before ordering carpet.
- Account for irregular shapes: Break complex rooms into rectangles and add them together.
- Door clearance: Ensure doors can open over new carpet (may need trimming).
- Pattern matching: Patterned carpet requires extra material - use 15-20% waste.
- Carpet roll width: Standard rolls are 12 ft wide. Plan seams carefully.
- Get professional quotes: Use this estimate as a baseline when comparing contractor prices.
Waste allowance accounts for:
- Cutting and fitting around corners
- Seams and transitions
- Pattern matching
- Doorways and closets
- Unexpected issues during installation
