Our online stair calculator can help make this task a breeze. Related Topics . Enter the thickness of the treads in the field labeled (E) in the stair … And the calculator figures out the spacing for the lengths as before: $$A_1 = Rise × sin⁡\,\alpha_2 = 7.06\,in × sin\,55.86^o = 5.84\,in$$, $$A_2 = Stringer\,Width – A_1 = 12\,in – 5.84\,in = 6.16\,in$$, $$C_2 = \sqrt{Run^2 – {A_1}^2} = \sqrt{(10.41\,in)^2 – (5.84\,in)^2} = 8.62\,in$$, $$C_3 = A_1 × tan\,⁡\alpha_2 = 5.84\,in × tan\,55.86^o = 8.62\,in$$, $$B_1 = \sqrt{Rise^2 – {A_1}^2} = \sqrt{(7.06\,in)^2- (5.84\,in)^2} = 3.96\,in$$, $$B_2 = A_2 × tan⁡\,⁡\alpha_1 = 6.16\,in × tan⁡\,34.14^o = 4.17\,in$$, $$B_3 = (Rise -Tread\,Thickness) × cos⁡\,⁡\alpha_2 = (7.06\,in – 2\,in) × cos\,55.86^o = 2.84\,in$$, $$A_3 = (Rise – Tread⁡\,Thickness) × cos⁡⁡\,⁡\alpha_1 = (7.06⁡\,in – 2⁡\,in) × cos⁡⁡\,34.14^o = 4.19⁡\,in$$, $$A_4 = Stringer\,Width – A_3 = 12\,in – 4.19\,in = 7.81\,in$$, $$C_4 = A_4 × tan\,\alpha_2 = 7.81\,in × tan⁡\,55.86^o = 11.52\,in$$. dimensions on the layout plan.

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 As before, including the tread when considering the run of the steps gives: Thus, our calculator works out the total horizontal distance between the edge of each step. Posted on by . Math isn’t my strongest suit, so I always use a calculator to figure out stuff like the rise and run of stairs. Finally, the calculator works out the total stringer length as before: $$Stringer\,Length = C_3 + B_3 + (Number\,of\,Steps – 1) × (B_1 + C_2) = 8.62\,in + 2.84\,in + (17-1) × (3.96\,in + 8.62\,in) = 212.72\,in$$. No! To calculate a spiral staircase, a half spiral, quarter spiral, helical or even straight with a curvature, you just need to think of it as straight and apply the formulas to the pitch line The pitch line is 50cm from the interior handrail, or in the middle, if the clearance width is less than a meter. You will need approximately 4' of carpet to cover the width, to allow the carpet to flow through the posts and wrap around the outside of the stair. Calculate the number of spindles needed and the space in-between the spindles. 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! We shall take you through the example calculations for first a standard mount, and then a flush mount set of stairs. You can calculate and create detailed and precise stairs plans. 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: $$Rise\,of\,steps = Total\,Rise = 120\,in$$. Calculating the stringer length is the same method as for the standard mount. However, a good guide is that any business or church, organization, office or commercial property should meet the given stair standards of your home country. Make sure you don’t round your answer before the final calculation. Now … Now, using a standard mount staircase, the vertical height rise of the steps will be one step less than with a flush mount because the final step is taken up by the decking. A stair that has one open side with railing posts on it is known as a cap stair. Before laying out your tools and getting started, you need to make sure each step will be identical in both size and shape. Order custom made glass balutrades for your stairs or landing.

Link to Lowe's Home Improvement Home Page Lowe's Credit Cards Order Status … 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. The calculator works out all these distances using the method given below: $$A_1 = Rise × sin⁡\,\alpha_2 = 7.06\,in × sin\,57.46^o = 5.95\,in$$, $$A_2 = Stringer\,Width – A_1 = 12\,in – 5.95\,in = 6.05\,in$$, $$C_2 = \sqrt{Run^2 – {A_1}^2} = \sqrt{(11.06\,in)^2 – (5.95\,in)^2} = 9.32\,in$$, $$C_3 = A_1 × tan\,⁡\alpha_2 = 5.95\,in × tan\,57.46^o = 9.33\,in$$, $$B_1 = \sqrt{Rise^2 – {A_1}^2} = \sqrt{(7.06\,in)^2- (5.95\,in)^2} = 3.8\,in$$, $$B_2 = A_2 × tan⁡\,⁡\alpha_1 = 6.05\,in × tan⁡\,32.54^o = 3.86\,in$$, $$B_3 = (Rise -Tread\,Thickness) × cos⁡\,⁡\alpha_2 = (7.06\,in – 2\,in) × cos\,57.46^o = 2.72\,in$$, $$A_3 = (Rise – Tread⁡\,Thickness) × cos⁡⁡\,⁡\alpha_1 = (7.06⁡\,in – 2⁡\,in) × cos⁡⁡\,32.54^o = 4.26⁡\,in$$, $$A_4 = Stringer\,Width – A_3 = 12\,in – 4.27\,in = 7.74\,in$$, $$C_4 = A_4 × tan\,\alpha_2 = 7.74\,in × tan⁡\,57.46^o = 12.12\,in$$. Therefore, you are enabled to construct the stairs yourself and don’t worry if the dimensions are correct. 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.

You may calculate the length and height of the tread or rise of the staircase by using the following calculator. Effectively plan your project with the many helpful calculators at Lowes.com. Design & Buy Glass Balustrades. The calculator first figures out the angles: $$\alpha_2 = 90^o – \alpha_1 = 90^o – 34.14^o = 55.86^o$$, $$\alpha_3 = 90^o + \alpha_2 = 90^o + 55.86^o = 145.86^o$$, $$\alpha_5 = 90^o + \alpha_1 = 90^o + 34.14^o = 124.14^o$$. Real-time graphics. Headroom Check. In doing so, we shall calculate the dimensions of the steps and the staircase.

Calculator Design Analysis. Раз-два-раз, вовочка *******. 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.
