What is the formula for calculating stairs?
How to Calculate Stairs – Example 1 450mm / 150mm = 3. This tells us that with a riser of 150mm we will need 3 risers/steps. 450mm / 2 = 225mm. Twice the Rise plus the Going (2R + G) should be between 550mm and 700mm. 2 x 150mm + 275mm = 575mm.
How is railing quantity calculated?
Steps to Estimate Balusters and Spindles To account for the post thickness, simply multiply the number of posts by the thickness, then subtract from the railing length. For example, a 10′ railing with 3 3½”(4×4) posts would have a total length of 120″ – (3 × 3½”) = 120″ – 10.5″ = 109.5″.
