Exterior stairs - Calculate slope

There are many formulas to calculate the slope of stairs. However, external staircases with their manifold characteristics are often completely forgotten. For them, the slope should not be as high as in the interior stairs. Which slope is sensible and customary for an external staircase is shown here in the overview.

External staircase requirements

If you need to install a continuous outside staircase or if you need to use a clearer slope for the stairs, you should install two handrails. These not only ensure a perceived safety, but also visually soften a steep staircase.
