How Do You Calculate the Total Amount of Carpet Required for Winding Stairs?

To calculate the total amount of carpet required for winding stairs, you need to measure the stair dimensions accurately and consider the layout of the carpet.

First, measure the width and depth of each stair tread. The width is the horizontal distance from one side of the stair to the other, while the depth is the distance from the front edge to the back edge. Follow these steps to ensure accurate calculations:

Measure Stair Treads: Use a tape measure to find the width and depth of each tread. The average tread width is typically about 36 inches.
Measure Stair Risers: Measure the height of each riser, which is the vertical part of the stair between each tread. Standard riser height is about 7 to 8 inches.
Calculate Total Area for Treads: Multiply the total number of treads by the area of each tread. If you have ten treads, and each tread measures 36 inches wide by 12 inches deep, the area is:
Area of each tread = Width × Depth = 36 inches × 12 inches = 432 square inches
Total area for 10 treads = 10 × 432 square inches = 4,320 square inches.
Calculate Total Area for Risers: Multiply the total number of risers by the area of each riser. If the risers are 36 inches wide and 8 inches high, the area is:
Area of each riser = Width × Height = 36 inches × 8 inches = 288 square inches
Total area for 10 risers = 10 × 288 square inches = 2,880 square inches.
Convert Square Inches to Square Feet: Since carpet is often sold in square feet, convert the total area from square inches to square feet by dividing by 144 (the number of square inches in a square foot).
Total area for treads: 4,320 ÷ 144 = 30 square feet
Total area for risers: 2,880 ÷ 144 = 20 square feet.
Add Areas Together: Add the total areas of the treads and risers for the overall area required.
Total area required = 30 square feet (treads) + 20 square feet (risers) = 50 square feet.
Account for Patterns and Waste: Consider additional carpet material for patterns, cuts, or waste, usually about 10%. Therefore, multiply the total area by 1.1:
Adjusted total = 50 square feet × 1.1 = 55 square feet.

By following these detailed steps, you can accurately determine the total amount of carpet required for winding stairs.
