Calculate carpet square footage from room length and width, multiple rooms, or known area. Estimate carpet square yards, carpet rolls, padding, waste, tack strip, seams, and project cost.
Single room mode:
The calculator multiplies room length by room width and subtracts any excluded area.
Multiple rooms mode:
The calculator multiplies one room area by the number of same-size rooms.
Known area mode:
The calculator starts from your known carpet area and estimates waste, square yards, padding, roll length, and cost.
Room with closet mode:
The calculator adds the closet or extra area to the main room before calculating carpet material.
A carpet area calculator helps estimate square footage for bedrooms, living rooms, basements, hallways, closets, apartments, and carpet replacement projects.
It can help calculate net carpet area, carpet square yards, carpet linear feet, padding rolls, tack strip length, transition length, waste, and estimated project cost.
Your result shows gross carpet area, excluded area, net carpet area, area with seam allowance and waste, carpet square yards, carpet linear feet based on roll width, padding rolls, tack strip length, transition length, and estimated cost.
Multiply the room length by the room width. For example, a 12 foot by 10 foot room has 120 square feet of carpet area.
Divide square feet by 9. For example, 120 square feet equals 13.33 square yards.
Many carpet projects use 10% to 15% extra for seams, cuts, closets, pattern matching, waste, and room shape. Complex layouts may need more.
Divide the carpet area with waste by the carpet roll width. For example, with a 12 foot roll, 240 square feet needs about 20 linear feet.
No. It is an estimate. Actual carpet needs vary by roll width, seam placement, pattern repeat, stairs, closets, room shape, installer method, and waste.
