The general rule for standard stair dimensions that is accepted by many general contractors and stair designers across the United States is known as the "7-11" rule. This means the rise is 7 inches and the run is 11 inches.
Standard Dimensions For Stairs
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.

For standard spiral staircase dimensions, it should be from 3 feet 6 inches in diameter and a walking path of 17 inches to 6 feet in diameter with a 32-inch walking path. The guidelines for spiral stair installations tend to be different from regular staircases because these can be trickier to navigate. Vertical Rise and Headroom Vertical Rise

→ 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.
