How to Measure Carpet for Stairway

Installing carpet on stair steps can be a difficult and laborious process. Prior to starting this project, you will need to take measurements for calculating the amount of carpet needed to cover the stairs. While you can install many different types of carpet on your stairs, the measurements for the carpet will often be the same. An important reminder when measuring for stairs is to always add extra for the curves and detail on the stairs.

Things You'll Need

• Tape measure

Instructions

1. Measure the width of the stair tread, which is the part you step on. Start from the left and measure to the right on the tread. Write this figure down.

2. Place the end of the tape measure on the inside part of the step, where the tread and riser meet. Pull the tape measure down to the bottom of the riser of the next lower step where it meets the next lower tread. Add two inches to this figure and write it down.

3. Multiply the stair width by the length measurement. Write this figure down.

4. Count the number of stairs in the stairway.

5. Multiply the figure by the number of stairs. This will be the total square feet of carpet necessary for the project.

6. Divide the figure by 9 to get the total square yards of carpet needed.

Tips & Warnings

• Have a professional measure your stairs for carpet if you do not think you have done so properly. Many carpet suppliers and vendors offer free measurements and estimates for carpet.
