It’s important to have the right ratio of tread to rise to make going up and down safe and easy. In general, the smaller the rise, the bigger the tread. You can choose what’s comfortable for you but generally outdoor steps have a rise of 5 ½ to 7 inches and a tread of 12 to 18 inches.

The BOCA guidelines also specify a minimum tread depth of nine inches and allow for a one inch protrusion, which is known as nosing. Some safety groups instead suggest a minimum tread of 11 inches.

What should the height of the steps be?

The aim is to create a good rhythm for people when walking up and down steps, so a lower riser height (e.g. 100mm) is usually accompanied by a deeper tread depth (say, 500mm), and vice versa – so a riser height of 200mm would normally be associated with a shallower tread depth (say 250mm).

How is the tread of a stair step measured?

The stair tread is the horizontal walking surface (red arrow) of an individual step. The tread depth is measured from the forward edge of the step nose or edge of the step above out to the leading edge of the step being measured – the space beneath my foot in the photo at left.
