Carpet Calculator

Calculate square yards, linear feet of roll, and cost of carpet needed for any room

Frequently Asked Questions

Why is carpet sold by the square yard?

Carpet is manufactured and priced per square yard, where one square yard equals 9 square feet. To compare a per-yard price to per-foot, divide by 9: $36 per sq yd is $4 per sq ft.

How much waste should I add for carpet?

Use about 10% for a simple rectangular room and 15–20% for L-shaped rooms, hallways, stairs, or patterned carpet that must be matched at the seams.

What is carpet roll width and why does it matter?

Carpet comes on fixed-width rolls - most often 12 ft, sometimes 13.5 or 15 ft. If your room is slightly wider than the roll, an extra seam and more waste result, so matching roll width to the room can lower cost.

Does the calculator include padding and installation?

No. It estimates carpet material only. Pad, tack strips, transition strips, and installation labor are separate costs you should budget on top.
