Stair Tread Measurement
Step 1 of 3

Step 1 · Step 1: Measuring Your Tread Depth
Place your tape measure firmly against the 'riser' (the vertical part at the back of the step). Extend the tape straight out over the flat part of the tread and over the rounded front edge, which is called the 'nosing'. Crucial Tip: For a true measurement, your stairs must be bare. Measuring over old carpet, pads, or adhesive will result in treads that don't fit properly. Keep the tape measure level and record this depth measurement for each step.
Don't measure over existing carpet, vinyl, or adhesive; it throws off your depth.
Ensure the tape measure is kept flat and level over the nosing for an accurate measurement.

General Hazard
Do not measure over old flooring, carpet, or adhesive, as this will throw off the depth measurement.
