Estimate carpet area in square yards and its cost.

Room length

Room width

Price per yd² ($)

Carpet needed (yd²) 22

Carpet needed 198

Total cost ($) 0

Formula: yd² = length × width ÷ 9 × (1 + waste)

Step-by-step with your numbers:

1. Values used:

2. Room length = 15

3. Room width = 12

4. Waste = 10 %

5. Price per yd² = 0 $

7. Carpet needed = 22yd²

8. Carpet needed = 198

9. Total cost = 0$

Did we solve your problem today?

Carpet is usually priced per square yard. This tool converts your room size into square yards (with waste) and an estimated cost.

The math behind it

Area (ft²) = length × width, plus waste for seams and trimming.

Square yards = ft² ÷ 9.

15×12 ft room = 180 ft²; with 10% waste = 198 ft² ÷ 9 = 22 yd².

Why add waste for carpet?

Carpet comes in fixed roll widths (often 12 ft), so seams and trimming create offcuts.
