No! beside the section you need help with., … ; D1 — internal diameter – this is the diameter of the central column. Stairs Calculator. By our stair calculator, you are able to perform an accurate estimation of metal or wooden stairway and compute the amount of construction materials needed to install it. And the calculator figures out the spacing for the lengths as before: $$A_1 = Rise × sin⁡\,\alpha_2 = 7.06\,in × sin\,55.86^o = 5.84\,in$$, $$A_2 = Stringer\,Width – A_1 = 12\,in – 5.84\,in = 6.16\,in$$, $$C_2 = \sqrt{Run^2 – {A_1}^2} = \sqrt{(10.41\,in)^2 – (5.84\,in)^2} = 8.62\,in$$, $$C_3 = A_1 × tan\,⁡\alpha_2 = 5.84\,in × tan\,55.86^o = 8.62\,in$$, $$B_1 = \sqrt{Rise^2 – {A_1}^2} = \sqrt{(7.06\,in)^2- (5.84\,in)^2} = 3.96\,in$$, $$B_2 = A_2 × tan⁡\,⁡\alpha_1 = 6.16\,in × tan⁡\,34.14^o = 4.17\,in$$, $$B_3 = (Rise -Tread\,Thickness) × cos⁡\,⁡\alpha_2 = (7.06\,in – 2\,in) × cos\,55.86^o = 2.84\,in$$, $$A_3 = (Rise – Tread⁡\,Thickness) × cos⁡⁡\,⁡\alpha_1 = (7.06⁡\,in – 2⁡\,in) × cos⁡⁡\,34.14^o = 4.19⁡\,in$$, $$A_4 = Stringer\,Width – A_3 = 12\,in – 4.19\,in = 7.81\,in$$, $$C_4 = A_4 × tan\,\alpha_2 = 7.81\,in × tan⁡\,55.86^o = 11.52\,in$$. Measure the width of 1 tread with a tape measure. ; D1 — staircase overall diameter – determined my the distance between end points of two steps which point opposite directions. ; W – thickness of steps – usually is a geometric parameter of the material (e.g. ; X – width of the opening (total run) – depends on how much space you can allocate in your house for the staircase. Tradestairs.com is operated by Stairplan Ltd - Leaders in the UK Staircase Industry - Minimum Order Levels Apply . The total design height of your project measured in inches. These small rounding errors can have a great difference on the final answer! Dropped Flush. A fraction to decimal conversion table for common fractions used in measurements is also provided at the bottom of the page. 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: $$\alpha_2 = 90^o – \alpha_1 = 90^o – 32.54^o = 57.46^o$$, $$\alpha_3 = 90^o + \alpha_2 = 90^o + 57.46^o = 147.46^o$$, $$\alpha_5 = 90^o + \alpha_1 = 90^o + 32.54^o = 122.54^o$$. The Calculator. Let us help you calculate your stair design. Live Help. Use our stair and step calculator and get your total stinger length, riser dimensions, and more with Decks.com. To print a paper template to mark outside tread curve, go to Full Scale Arc Templates and enter . In addition, we will show you how the stair stringer calculator works out the rise, run, angle and stringer length, allowing you to plan the layout of your intended staircase effectively. 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. 2 Tread Board Type. Sometimes during measured survey work, you often cannot measure elements such as walls due to access and safety issues. 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. For school buildings, the preferred rise is 150 mm and the preferred going is 280 mm. H — the height of the staircase – usually determined by the distance between the floors in your house. Don’t forget though, this is for a commercial property. Article By: Tom Ayre | Last Update: November 2020.

The Stair Calculator is an online tool for calculating various parameters involved in the construction of stairs. Often you only need an approximate measurement and can use photographs to count bricks to get an approximate length. Target Riser Height . Finally, the calculator works out the total stringer length as before: $$Stringer\,Length = C_3 + B_3 + (Number\,of\,Steps – 1) × (B_1 + C_2) = 8.62\,in + 2.84\,in + (17-1) × (3.96\,in + 8.62\,in) = 212.72\,in$$. With over 30 Years experience, Stairparts Direct specialise in the manufacture and supply of high quality stairparts. Our staircase spindles, newel posts, caps, bases and … 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: $$Rise\,of\,steps = Total\,Rise = 120\,in$$. Fraction. Now, if we consider a single step of the staircase, the total horizontal distance will be given by: $$Total\,Horizontal\,Distance = Run + Tread\,Overlap + Riser\,Thickness = 11.06\,in + 2\,in + 1\,in = 14.06\,in$$. Even though we have based the calculations on the IRC, you must always check with local building codes to ensure there are no variances. For ease of understanding, again, see the reference picture. 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. 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. Refer to the figure adjacent to the calculator as a reference.

To use our stair calculator, you need to enter the following measurements as a minimum: Using these values, our calculator works out the vertical height rise of each individual step with the fraction: $$Rise = {Total\,Rise \over Number\,of\,Steps}$$. The calculator works out all these distances using the method given below: $$A_1 = Rise × sin⁡\,\alpha_2 = 7.06\,in × sin\,57.46^o = 5.95\,in$$, $$A_2 = Stringer\,Width – A_1 = 12\,in – 5.95\,in = 6.05\,in$$, $$C_2 = \sqrt{Run^2 – {A_1}^2} = \sqrt{(11.06\,in)^2 – (5.95\,in)^2} = 9.32\,in$$, $$C_3 = A_1 × tan\,⁡\alpha_2 = 5.95\,in × tan\,57.46^o = 9.33\,in$$, $$B_1 = \sqrt{Rise^2 – {A_1}^2} = \sqrt{(7.06\,in)^2- (5.95\,in)^2} = 3.8\,in$$, $$B_2 = A_2 × tan⁡\,⁡\alpha_1 = 6.05\,in × tan⁡\,32.54^o = 3.86\,in$$, $$B_3 = (Rise -Tread\,Thickness) × cos⁡\,⁡\alpha_2 = (7.06\,in – 2\,in) × cos\,57.46^o = 2.72\,in$$, $$A_3 = (Rise – Tread⁡\,Thickness) × cos⁡⁡\,⁡\alpha_1 = (7.06⁡\,in – 2⁡\,in) × cos⁡⁡\,32.54^o = 4.26⁡\,in$$, $$A_4 = Stringer\,Width – A_3 = 12\,in – 4.27\,in = 7.74\,in$$, $$C_4 = A_4 × tan\,\alpha_2 = 7.74\,in × tan⁡\,57.46^o = 12.12\,in$$.
