Consider all of the possibilities and think them through, before cutting your first stringer. The top tread would either have a gap on the back side of the tread, or the nose of the tread would not have the same overhang as the other treads. Using the diagram below, picture the top step without the last riser installed.

Depending on your design, you may need to adjust the depth of your stringer's top step.įor example, if you are not planning to add a riser to the last rise, up to your deck or landing, you may want to subtract the thickness of one riser from the calculated Tread Depth on the top step of the stringers. In most cases, a flight of stairs will require solid risers, unless the Total Rise is less than 30 inches (762 mm) OR the typical Step Height is less than 5 1/2 inches (140 mm) (see the Risers section below for related building code requirements).Īdding solid risers to your stairs will not change the results of the Stair Calculator, so long as you properly attach the risers before you add the treads, as shown in the Stairs with Solid Risers and 2x12 Treads diagram below.īefore cutting your stringers, double-check all of your measurements, and carefully plan how you are going to attach (or not attach) a solid riser at the upper connection point of your stringer.
