Step 2 · Measure the Depth of Each Tread
For each step, place your tape measure firmly against the vertical panel at the back of the tread (that's the 'riser'). Extend the tape straight across the flat part of the stair, continuing over the rounded front lip, which we call the 'nosing'. It's critical to keep the tape measure flat and level for an accurate reading. For safety and quality, always measure the bare wood. Measuring over old carpet, glue, or debris will throw off your numbers and compromise your final look. Record the depth for each step.
Don't measure over existing carpet, vinyl, or adhesive; it throws off your depth.
The standard residential tread depth is typically between 10–11 inches, but always verify with your own stairs.

General Hazard
Do not measure over old flooring, carpet, or adhesive as it will skew the depth measurement.
