What is a comfortable rise and run for stairs?
With a riser height of 7 1/2 inches, tread width (run) should be at least 9 inches. Ten inches is a more comfortable run; when you multiply 7 1/2 inches by 10 inches, you get 75 — within the conventional ratio of 72 to 75 inches. With 14 10-inch treads, the total run of the stair will be 140 inches.
What is the total run of a standard staircase?
Total Run [G] – The Total Run is the horizontal length of a stair stringer. It is equal to the number of treads multiplied by the typical Tread Depth [B]. Risers – the Step Height [F] is the typical height of each step. Code states that this should not be greater than 7 3/4 inches (194 mm).
What is average rise for stairs?
Three feet is better, and 3′6″ is the standard for normal occupancy. If a stair is more than 44 inches wide, a handrail is required on both sides.” Step height should be between 4 inches to 8 inches high.
What is the standard rise?
Stair ” rise height” is the vertical height or distance between the surface of two stair treads (what you actually step on). The general rule in the United States is a 7″ rise and 11″ tread depth.
How do you calculate the rise and run of stairs?
To calculate the rise, or height, of a stairway, measure the height from one floor level to the next. Divide that total by 22 cm (8 11/16 inches) to see how many stairs you will need. Multiply the number of stairs by the expected width of each tread or step to determine the run, or the length of the stairway.

What is the rise and run formula for stairs?
Riser+Tread = 17.5 inches: 7.5 inches for the riser height; 10 inches for the tread depth.
