Stair Stringer Thickness

We shall calculate the dimensions of the steps and the staircase.
Stair stringer thickness. The stringer mount type refers to how the stringer will be attached to the upper landing or deck frame. Once the stair results have been calculated you can toggle between the standard and flush options to compare the differences. If the stair treads are set into grooves routed into the stringer in a 2x stringer the groove depth should be 1 2 the thickness of the stringer typically 3 4 and additional support by cleats or by gluing and end screwing through the stringer sides into the treads is good practice. In addition we will show you how the stair stringer calculator works out the rise run angle.
We shall take you through the example calculations for first a standard mount and then a flush mount set of stairs. Riser thickness of 1 inch. As an fyi me showing using these plans is not an issue as all the ones that have been or are used in competition are shared with all the teachers afterwards so they can use them as guides teaching tools. We sell pre made standard stringer boards to 32mm thickness and 244mm height.
We strongly recommend using stair stringers of a minimum width of 32mm as anything less can result in squeaky treads in your staircase. Since the tread depth b is a constant when using the automatic stair calculator the total run g will vary when you toggle between the two mount options. These are available in 2 4 3 6 and 4 2m lengths direct from our online shop. You can now draw the notches for the stairs onto your 2x12 stair stringers.
The difference between the stair rises and tread depths cannot vary by more than 3 8 from the largest to the smallest. And a stringer width of 12 inches.
