Step 2 · Measure the Tread Depth
For each step, place your tape measure firmly against the vertical riser. Extend it straight across the flat part of the tread and over the rounded front edge, which we call the 'nosing'. It's crucial that the tape lies perfectly flat and level. Safety-conscious tip: Never measure over old carpet, staples, or glue residue. Measuring the bare wood is the only way to get an accurate depth for a tread that will fit securely and look seamless. Carefully record the depth for every single step.
Don't measure over existing carpet, vinyl, or adhesive; it throws off your depth.
General Hazard
Do not measure over old flooring, carpet, or adhesive, as it throws off the depth.
