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.
Stair tread riser calculator.
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.
Treads may be cut to suit other widths.
The stair stringer calculator allows you to perform online calculation of straight staircases on strings.
Is there a head height restriction.
Total area for all treads and rises 7 66m to calculate and display upper floor opening and stair head room enter upper floor thickness check the show head room check box and drag the head slider to calculate and animate diagram head room and floor opening.
The program generates the results of the calculations of the 3d model straight staircase drawings of all structural elements with straight stair 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.
The stair calculator is an online tool for calculating various parameters involved in the construction of stairs.
This calculator will tell you.
Total required number of tread total stair tread or run width of one tread 90 10 9 tread.
Refer to the figure adjacent to the calculator as a reference.
Enter total stair run.
The rise is the vertical measurement taken from one step level to the next standard rise is 175mm.
Either b or c is required.
We suggest 10 5 for 2x12 or 2 2x6 treads.
Interior stairs tread and riser ratio the typical interior stair dimension is calculated as the formula riser r tread t 17 inches minimum or 18 inches maximum not including the nosing.
The nosing is the projecting edge of a tread.
Enter total stair rise inches.
A fraction to decimal conversion table for common fractions used in measurements is also provided at the bottom of the page.
How many rises you ll need dimensions for each rise.
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.
