Step 2 · Step 2: Measure Your Tread Depth (The Run)

For each individual step, place the end of your tape measure firmly against the vertical riser at the back. Extend the tape straight across the tread, going over the front edge or 'nosing'. It is crucial that your tape measure stays flat and level for an accurate reading. A critical safety note: Never measure over existing carpet or old flooring, as this will skew your numbers and prevent your new treads from fitting securely.
