Step 1 · Measure Your Tread Depth

To ensure safety and a perfect fit, use a tape measure to find the distance from the very front edge of a step (this overhang is called the 'nosing') back to the vertical board (the 'riser'). Getting this number right is essential for ensuring your foot has plenty of room, which is a cornerstone of stair safety. This measurement is your guide for a perfect fit.
