Carpet Area Calculation in Square Feet
Calculate carpet area for any room shape with cost estimation
Select Room Shape
For custom shapes, divide your area into simple shapes (rectangles, triangles, etc.), calculate each separately, and add them together.
What is Carpet Area?
Carpet area refers to the actual floor area that can be covered with carpet. It’s typically measured in square feet and is used to determine how much carpet material you’ll need for a room or project.
Why Calculate Carpet Area?
- Accurately estimate the amount of carpet needed
- Calculate the cost of carpeting a room or entire house
- Plan for installation time and resources
- Compare different carpet options based on price per square foot
Tips for Measuring Carpet Area
- Always measure at the room’s widest points
- For irregular shapes, break the room into rectangles and triangles
- Add 5-10% waste factor for standard installations
- Add 15-20% waste factor for patterned carpet or diagonal installations
- Include closets and alcoves in your measurements
Frequently Asked Questions
How do I measure carpet area for irregularly shaped rooms?
For irregular rooms, divide the space into standard shapes like rectangles and triangles. Measure each section separately, calculate the area for each, then add them together to get the total carpet area.
What is a waste factor, and why is it important?
A waste factor accounts for material that will be trimmed during installation due to room irregularities, pattern matching, and cutting errors. For most carpet installations, a 10% waste factor is standard, while patterned carpets may require 15-20%.
How do I convert between square feet and square yards for carpet?
To convert square feet to square yards, divide the square footage by 9. For example, 180 square feet equals 20 square yards (180 รท 9 = 20). To convert square yards to square feet, multiply by 9.
What affects the cost of carpet installation?
Carpet installation costs are affected by room size, carpet type and quality, padding quality, furniture removal, old carpet removal, floor preparation, and regional labor rates.
