Step 2 · Measure Each Tread's Depth

Now, let’s measure the depth of each tread one by one. This ensures a perfect fit that maximizes safety and comfort. Place the end of your tape measure flat against the vertical riser at the back of the step. Extend the tape straight across the tread, making sure it passes over the rounded front edge, which we call the 'nosing.' Keeping the tape measure perfectly flat and level is key to an accurate measurement. Important: For a true reading, make sure you are measuring the bare wood, not any old carpet, padding, or adhesive residue that might still be on the stair. Write down the depth for each step as you go.
