This is intended to the calculations, formulae and explanations easier to follow. Mar 17, 2017 - This free stair calculator determines stair parameters such as rise, total run, and angle, stringer length, based on height, run, tread, and headroom requirement. We simply remember that the final step takes us onto the decking. First, we calculate the vertical height rise of each step: $$Rise = {Total\,Rise \over Number\,of\,Steps} = {120\,in \over 17} = 7.06\,in$$. Measure the Tread Thickness. Easy to use free stair calculator by EZ Stairs. Calculator Design Analysis. If it is decided to increase the And the angle between the horizontal and the stairs is once again given by: $$tan\,\alpha_1 = {Rise\,of\,steps \over Run\,of\,steps} → \alpha_1 = tan^{-1} {Rise\,of\,steps \over Run\,of\,steps} = tan^{-1} {120\,in \over 177\,in} = 34.14^o$$. https://codes.iccsafe.org/content/IBC2018P4/chapter-10-means-of-egress#IBC2018P4_Ch10_Sec1011, 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, Stringer Width – The total diagonal measurement between the edge of the step and the back line, For both our examples below, we imagine we want to have 17 steps running up to a landing with a total vertical height rise of 120 inches and total horizontal run of 180 inches, Let’s say that we have a tread thickness of 2 inches. Method 2 : The walkline is located half-way along the stair width Method 3 : The walkline is located 2/3 of the way along the stair width, measured towards the inner handrail Method 4 : The walkline is located 50cm (20") from the outer handrail Calculate steps unit rise and run in stairs.

The first stair start form the bottom to the landing and the second stair design form the landing to the top. A stair that has one open side with railing posts on it is known as a cap stair. Calculating the stringer length is the same method as for the standard mount. Finally, the calculator works out the total stringer length as before: $$Stringer\,Length = C_3 + B_3 + (Number\,of\,Steps – 1) × (B_1 + C_2) = 8.62\,in + 2.84\,in + (17-1) × (3.96\,in + 8.62\,in) = 212.72\,in$$. Enter the depth of your upper floor in mm. In doing so, we shall calculate the dimensions of the steps and the staircase. Our calculator is programmed to give accurate measurements within the guidance of the Council of American Building Officials and International Code Council. Doing this work is much easier using metric measurements. Section 1011 has lots of information from the 2018 international building code. Number of Tread = Length of Stair/One number of Tread. All calculators on this site are geometric only. between the horizontal and the staircase is calculated by: $$tan\,\alpha_1 = {Rise\,of\,steps \over Run\,of\,steps} → \alpha_1 = tan^{-1} {Rise\,of\,steps \over Run\,of\,steps} = tan^{-1} {112.94\,in \over 177\,in} = 32.54^o$$, Now, to find the stringer length of the staircase requires some more complicated Mathematics. Even though we have based the calculations on the IRC, you must always check with local building codes to ensure there are no variances. . Simply put in values for the total run and rise, along with some measurements for the individual steps to calculate the layout of your staircase! After input of necessary initial data, you will get detailed drawings of the 90 degree turn stair with an interactive 3D visualisation, all stair dimensions you will need to … . Calculating the rise, run, angle and stringer length for a flush mount is very similar to the standard mount. The estimator does the conversions for you using the following ratios: $$1\,foot = 12\,inches = 0.33\,yards = 30.48\,centimeters = 0.3048\,meters$$. You can calculate and create detailed and precise stairs plans. Fig. Run/Tread: The run or tread is the part of the stairway that a person steps on. The calculator works out all these distances using the method given below: $$A_1 = Rise × sin⁡\,\alpha_2 = 7.06\,in × sin\,57.46^o = 5.95\,in$$, $$A_2 = Stringer\,Width – A_1 = 12\,in – 5.95\,in = 6.05\,in$$, $$C_2 = \sqrt{Run^2 – {A_1}^2} = \sqrt{(11.06\,in)^2 – (5.95\,in)^2} = 9.32\,in$$, $$C_3 = A_1 × tan\,⁡\alpha_2 = 5.95\,in × tan\,57.46^o = 9.33\,in$$, $$B_1 = \sqrt{Rise^2 – {A_1}^2} = \sqrt{(7.06\,in)^2- (5.95\,in)^2} = 3.8\,in$$, $$B_2 = A_2 × tan⁡\,⁡\alpha_1 = 6.05\,in × tan⁡\,32.54^o = 3.86\,in$$, $$B_3 = (Rise -Tread\,Thickness) × cos⁡\,⁡\alpha_2 = (7.06\,in – 2\,in) × cos\,57.46^o = 2.72\,in$$, $$A_3 = (Rise – Tread⁡\,Thickness) × cos⁡⁡\,⁡\alpha_1 = (7.06⁡\,in – 2⁡\,in) × cos⁡⁡\,32.54^o = 4.26⁡\,in$$, $$A_4 = Stringer\,Width – A_3 = 12\,in – 4.27\,in = 7.74\,in$$, $$C_4 = A_4 × tan\,\alpha_2 = 7.74\,in × tan⁡\,57.46^o = 12.12\,in$$. Thus, our deck staircase calculator can figure out the total horizontal distance between the edge of each step (not forgetting that the final step is the decking! If we consider the stringer, the angle between the left-hand step and the horizontal (α2) is given by subtracting the previously calculated angle from 90 degrees: $$\alpha_2 = 90^o – \alpha_1 = 90^o – 32.54^o = 57.46^o$$, $$\alpha_3 = 90^o + \alpha_2 = 90^o + 57.46^o = 147.46^o$$, $$\alpha_5 = 90^o + \alpha_1 = 90^o + 32.54^o = 122.54^o$$. Thus, we transform the above formulae to get the vertical rise spacing: $$Rise\,of\,steps = Total\,Rise – Tread\,Thickness = 120\,in – 2\,in = 118\,in$$. Consider a single step, the total horizontal distance will be given by: $$Total\,Horizontal\,Distance = Run + Tread\,Overlap + Riser\,Thickness = 10.41\,in + 2\,in + 1\,in = 13.41\,in$$. Take 200mm as a riser (a nice round number and not too shallow). The deck stair calculator thus works out: $$Run\,of\,steps = Total\,Run – (Tread\,Overlap + Riser\,Thickness) = 180\,in – (2\,in + 1\,in) = 177\,in$$. ): $$Run = {Run\,of\,steps \over Number\,of\,steps} = {177\,in \over 16} = 11.06\,in$$. Please, Zoom out to fit large full scale template images on screen - or to adjust scale to match ruler held against screen. As before, we calculate the vertical height rise: Unlike the standard mount measurement, where we subtracted the final step from the rise, with a flush mount we have that: $$Rise\,of\,steps = Total\,Rise = 120\,in$$. How to calculate stairs To use our stair calculator, you need to enter the following measurements as a minimum: 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 A good guideline is given by the Council of American Building Officials and International Code Council. . $$Run = {Run\,of\,steps \over Number\,of\,steps} = {177\,in \over 17} = 10.41\,in$$. ... You may calculate the length and height of the tread or rise of the staircase by using the following calculator. We will show you how this can be done easily. If we refer back to the guidance we can use between 150mm and 220mm as a riser. But if I used a standard calculator, I’d have to enter measurements as decimals and convert the answers back into fractions, a process guaranteed to generate some bizarre numbers. Finally, the calculator combines the above calculated values to figure out the total stringer length of the steps: $$Stringer\,Length = C_3 + B_3 + (Number\,of\,Steps – 1) × (B_1 + C_2) = 9.33\,in + 2.72\,in + (16-1) × (3.8\,in + 9.32\,in) = 208.88\,in$$.
