A fraction to decimal conversion table for common fractions used in measurements is also provided at the bottom of the page.
Stair tread riser calculator.
We suggest 10 5 for 2x12 or 2 2x6 treads.
Use if total run is restricted by obstacles such as doors or landings.
How many rises you ll need dimensions for each rise.
How to calculate stairs to use our stair calculator you need to enter the following measurements as a minimum.
The rise is the vertical measurement taken from one step level to the next standard rise is 175mm.
The stair calculator is used for calculating stair rise and run stair angle stringer length step height tread depth and the number of steps required for a given run of stairs.
The nosing is the projecting edge of a tread.
Enter total stair rise inches.
For convenience and flexibility this stair stringer calculator comes in two forms the automatic and manual.
Refer to the figure adjacent to the calculator as a reference.
Total required number of tread total stair tread or run width of one tread 90 10 9 tread.
The stair stringer calculator allows you to perform online calculation of straight staircases on strings.
Total run the total horizontal length of the stair stringer total rise the vertical height between the bottom of the first step and the top of the final step in the stair stringer.
Is there a head height restriction.
Treads may be cut to suit other widths.
Our stair stringers range from 1 17 treads steps and are made for standard rise and going and work on a 1000mm between centres of the stringers.
To simplify the process we ve created this deck stair calculator to help you determine the correct measurements needed to carry out your project.
Either b or c is required.
Enter total stair run.
The stair calculator is an online tool for calculating various parameters involved in the construction of stairs.
The program generates the results of the calculations of the 3d model straight staircase drawings of all structural elements with straight stair stringers.
