To meet building code requirements, the stair railing should be mounted so that the top of the handrail height is 34 to 38 in. it's 1/2 inch shorter than the rest of the stairs -, I actually need to remove a half inch from the bottom most stair of the stringer to fit). At STAIR RISER SPECIFICATIONS you will find complete details about stair riser specifications and codes, including the following excerpts: Step riser specifications riser height (<= 7.75" or in some codes <= 7.0" or in Canada <=8.25") maximum and 4 inches (102 mm) minimum. modify the Actual Tread Depth stair instance property. I noticed that if I set our riser height to 7.125" (about 7 1/8") we will use an even number of risers (15). Any feedback is appreciated.

Matthew:We start by taking a reasonable step rise, say 7 inches (we can adjust that later),We divide the total rise by the unit or step rise.101" total rise / 7" rise per step = 14.4 so we need a little over 14 steps up to climb that height. Calculate the stair horizontal run distance: 4 treads, with a minimum tread depth of 11" would be 4 x 11 = 44". Stairs > Edit Stairs > Select Stairs 126. When adding a railing to Stringer, the path offset will be set half the value of the stringer width. A better stair design may involve increasing the rise and lengthening one or more steps into a platform of 36" or more of horizontal walking surface. The average height of a stair step in the United Sates is 7 1/2 inches, but safe and comfortable stair dimensions should be determined based on a number of factors including how long the step is, how much space the staircase should take up and … So just as you can't put ten pounds of flour into an eight pound sack, you cannot build your stairs to provide a safe step height and still fit them into that 112-inch horizontal distance - not as a straight run anyway.Worse still, 14 steps up without an intermediate landing may be prohibited by your local building department as too many steps up without a landing. If you use stair height of 10uu or 20uu and depth of 30uu, these will work for most walls without any decimals due to 10/20uu value. Be aware that the height of the handrail marks the height of the top of the handrail, which will extend … Now with 15 risers, if I make the individual tread depth (that's the horizontal tread run distance) 11 inches, our stairway will have a run of 15 x 11 = 165" in length. One way to adjust a stair to meet the headroom clearance requirement is to modify the landing height. [27] "The Dimensions of Stairs", J. M. Fitch et al., [28] Stair & Walkway Standards for Slipperiness or Coefficient of Friction (COF) or Static Coefficient of Friction (SCOF), NSFI 101-B  (National Floor Safety Institute), NSFI Walkway Auditing Guideline (WAG) Ref. Vertical Reach Height. What many stair builders do is simply lay a (hopefully straight) stair stringer between the two elevations, measure the actual rise and run distances, and lay-out the stair dimensions on the fly by measuring and marking along the side surface of the stringer. Also, twice the rise plus the run (2r+R) should be equal to 25 inches, also with a 1-inch deviation. IMO 1/4" is too much - trapping high heeled shoes; 1/8" may not be enough if the boards swell when wet. Apologies for the delay.
