How Can You Calculate Total Carpet Square Footage for Stairs?
To calculate total carpet square footage for stairs, measure the total length and width of each stair tread and riser, then apply the formula for square footage to find the total area.
- Measure the width of each stair tread (the part you step on). Common tread widths are about 10-12 inches.
- Measure the height of each riser (the vertical part of the step). Riser heights typically range from 7-8 inches.
- Count the total number of stairs. For example, if there are 12 stairs, ensure you include all treads and risers.
- Calculate the area of treads and risers using the formula:
– Area of one tread = Width x Depth
– Area of one riser = Width x Height - Multiply the area of one tread by the total number of treads. Then multiply the area of one riser by the total number of risers.
- Add the total tread area to the total riser area for the complete square footage needed for the stairs.
For example, if the tread is 10 inches wide and 12 inches deep, the area of one tread is 10 x 12 = 120 square inches. If the riser is 10 inches wide and 7 inches high, the area of one riser is 10 x 7 = 70 square inches. With 12 treads and 12 risers, the total area would be (120 x 12) + (70 x 12) = 1440 + 840 = 2280 square inches. Convert this to square feet by dividing by 144 (as there are 144 square inches in a square foot), resulting in 15.83 square feet.
Ensure to add an extra allowance for waste, typically 10% of the total calculated area, to account for cuts and fitting. Thus, consider purchasing approximately 17.41 square feet of carpet to cover the stairs completely.
