How is the size of the stair tread measured?
For each stair tread three measurements are given; width, length and rise.
Width is the measurement from the front to the back of the stair tread at its widest point.
Length is the measurement along the front edge of the stair treads.
The measurement of the rise refers to the height of the front edge of the stair tread, which will hang over the nose of the step.
Please note that all measurements on our website are given in centimetres.
