What is code for rise and run of stairs? The 2018 ibc building code for rise and run of stairs is a maximum 7″ rise and minimum 11″ run (tread depth). The osha standard for rise and run of stairs is maximum 9.5″ rise and minimum 9.5″ run (tread depth).
What Is the Standard Rise and Run of Stairs?
There is no definitive answer to this question as it depends on a number of factors, such as the height of the person using the stairs, the width of the stairs, and the angle of the stairs.
However, a general guideline is that the rise (height of each step) should be between 4 and 8 inches (10–20cm), and the run (depth of each step) should be between 8 and 12 inches (20–30cm).
There are a few things to bear in mind when using this guideline. Firstly, the rise should be greater than the run, as otherwise the stairs would be too steep and could be dangerous.
Secondly, the total height of the stairs should be divided evenly between the number of steps, so if you are building a staircase with 10 steps, each step should be around 4 inches (10cm) high.
Another important consideration is the angle of the stairs. If the stairs are too steep, they will be difficult to climb, and if they are too shallow, they will be difficult to descend.
A good angle to aim for is around 30 degrees, but again, this will vary depending on the individual. Once you have decided on the rise and run of your stairs, you need to make
