Measure Individual Stair Components

What happens in this clip

To start, use a reliable tape measure to determine the dimensions of your stairs. First, measure the **width of a single stair tread** from wall to wall or from stringer to stringer (the side supports of the staircase). In the video, the individual measures the width of a stair tread using a tape measure. Record this measurement carefully. Next, measure the **depth of the stair tread**, which is the horizontal surface where you step. Finally, measure the **height of the stair riser**, which is the vertical part of the stair. It is crucial to measure several steps, especially if there are variations, and use the largest measurements to ensure sufficient material coverage for all stairs. Also, count the total number of individual stairs, including any landings that might require carpet.

Goal: Begin by accurately measuring the width, tread depth, and riser height of a typical stair in your staircase. These foundational measurements are critical for calculating the total material needed for both underlayment and carpet.

About the full video

This detailed guide outlines the essential steps for accurately measuring stairs to determine the precise quantity of carpet and underlayment required for installation. It covers individual stair component measurements, the application of specific formulas to calculate material lengths per step, and the subsequent marking and cutting of underlayment and carpet strips. The process aims to minimize material waste and ensure a professional, well-fitted stair carpet installation.

Step 6 of 6: Document All Measurements and Irregularities

Review all the measurements taken for depth, width, and riser height for each step. Consolidate these notes along with any specific observations about out-of-square corners, unlevel surfaces, or structural issues. A diagram of the stairs with all dimensions clearly labeled can be very helpful. This comprehensive record ensures that you have all the necessary information to accurately order or cut replacement treads that will fit perfectly.
