How to calculate how much you need for the stairs

Calculating underlay for the stairs is easier than you might think:
Stair width x (tread size + 0.10m). Then multiply this by how many steps you have. The 0.10m is to allow for cutting, so you will need to add this to your tread size before you multiply it with stair width. Here’s an example:
0.91 x (0.30 + 0.10m) = 0.36m².
0.36m² x 12 steps = 4.32m².
We recommend rounding this up, so it would come to 5m².
