How do you calculate stairs for stairs?

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.

How thick are concrete stairs?

At minimum, the concrete thickness should be 4 inches between the inside of the step to the ground. In order to determine the number of risers, divide the total height of the steps by the number of risers desired. No individual riser should be greater than 7 to 7½ inches.
