The minimum recommended stair width is between 34" and 36" Across the width of the tread. Some codes such as CA/OSHA specify a minimum stairway width of 24" [35].. The minimum recommended stair landing length is 36" (or a length and width sufficiently greater than the swing of the door if a wider door is present.

To determine their length, square the run, square the individual stair rise, and then add the 2 numbers together. From there, find the square root of the answer for the length of each stringer. For instance, if the run is 10 inches, square 10 by multiplying it by itself to get 100.

Those who study stairs believe a pitch of between 20 and 50 degrees is safe, and being within the range of 30 to 35 degrees is best. Another rule of thumb for riser and tread design is that the sum of the two dimensions be between 17 and 17 and one-half inches. If a riser is seven inches high the tread depth should be no more than 10 and one.

Ideal Stair Rule of Thumb. Perfect stair (for most users): Rise = 7", Run = 11". The sum of one stair or step tread or "run" and one step height or "riser" should always be about 17" or 18" in total. As the step rise gets shorter. the step run must get longer.

→ stair will be comfortable Rule one says that rise plus run ( r+R) should equal 18 inches. Why? That's what most people find to be a comfortable stride on most stairs. You can cheat a bit up or down, but below 17" and more than 19" will result in steps that require strides either too big or too small for most people.

The standard size for a staircase in a residential home is typically between 9 and 12 feet long; although, this can vary depending on the height of your ceiling. To accurately calculate the length of your staircase, measure the distance between the floor on your first level and the floor of your second level carefully.

A: Rise. The distance from the floor to the top of the staircase. In this illustration, the total rise is 45 and 7/8 inches. B: Top Step. The top step can be slightly shorter than the other steps if the rise can't be divided evenly. It should be no more than 3/8 inches shorter than the bottom step. C: Total Run.
