How to Measure Your Room for Carpet
Even with a calculator, accurate measurements are crucial. Follow these steps:
Step 1: Measure the Length
Use a tape measure and record the longest wall of the room. Note it in meters or feet.
Step 2: Measure the Width
Measure the shortest wall. For irregular rooms, divide the room into rectangles or squares and measure each section separately.
Step 3: Subtract Fixed Furniture
If you have built-in cabinets, fireplaces, or other fixed furniture, subtract their area from the total.
Step 4: Add Extra for Pattern Matching
Most professionals recommend 5–10% extra carpet for cutting, fitting, and pattern alignment.

Example 3: Hallways and Stairs
- Hallway: 1.2m × 5m = 6 m²
- Stairs: 12 steps × 0.8 m² = 9.6 m²
- Total: 15.6 m² + 10% extra = 17.2 m² Carpet required: 18 m²
