How do I calculate my staircase length?

Divide the rise by 6 or 7 inches (15 or 18 cm) to find the total number of stairs. For larger stairs, divide by 6 and for smaller stairs, divide by 7. The total you get is how many stairs your future staircase will have so you can plan accordingly.

How do you calculate stairs for architecture?

How to Calculate Stairs – Example 1

1. 450mm / 150mm = 3. This tells us that with a riser of 150mm we will need 3 risers/steps.
2. 450mm / 2 = 225mm.
3. Twice the Rise plus the Going (2R + G) should be between 550mm and 700mm.
4. 2 x 150mm + 275mm = 575mm.

What is the length of a staircase?

For most homes, the length of a flight of stairs is between 9 and 12 feet long. The total length of a flight of stairs for an 8-foot ceiling is approximately 9-feet long. The total length of a flight of stairs for a 10-foot ceiling is approximately 12-feet long.

How are staircase dimensions and designs calculated?

2 Risers + 1 Tread = 63-65 cm

1. (2 x 21) + (1 x 21) = 63 cm.
2. (2 x 18) + (1 x 28) = 64 cm.
3. (2 x 13) + (1 x 39) = 65 cm.
4. (2 x 17.33 cm) + (1 x tread) = 64.

How do you calculate load of stairs?

(i) Loads on going (on projected plan area) (a) Self-weight of waist-slab = 25(0.25)(313.85)/270 = 7.265 kN/m2 (b) Self-weight of steps = 25(0.5)(0.16) = 2.0 kN/m2 (c) Finishes (given) = 1.0 kN/m2 (d) Live loads (given) = 5.0 kN/m2 Total = 15.265 kN/m2 Total factored loads = 1.5(15.265) = 22.9 kN/m2 (ii) Loads on …

What is the ideal stair rise and run?

The general rule (in the US) is 7-11 (a 7 inch rise and 11 inch run) (17.78cm-27.94cm). More exactly, no more than 7 3/4 inches (19.7cm) for the riser (vertical) and a minimum of 10 inches (25.4cm) for the tread (horizontal or step).

How many steps is 10 feet?

Length of Staircase for a 10 Foot Ceiling A staircase in a home with 10′ ceilings requires 17 steps. Stairs that have a tread depth of 11” will have a total length of 187”. Stairs with a tread depth of 10” will have a total length of 170”, which is the minimum length.
