The stair calculator calculates stair rise and run, stair angle, stringer length, step height, tread depth, and the number of steps required for a given run of stairs. For convenience and flexibility, this stair stringer calculator comes in two forms: automatic and manual. Click on the [?] icons to determine the best calculator for your stairs. 2 Rules for Building Comfortable Stairs As the rise goes down, the run needs to go up correspondingly, or vice versa. By Michael Maines Launch Gallery On the first stairs I built, I sized them for a 1×8 riser and a 2×8 tread. The result was a disastrously uncomfortable stair, with treads too short for adult feet.

Family Handyman The International Residential Code ( IRC) has specific instructions on the way stairs can be built. Here's a clear summary of what the IRC code says about stair codes for rise, run, and nosing. (Note: not every municipality adopts every part of every code, and some cities and states add in their own additional rules. The rise of each step, called the unit rise, is the vertical distance between the top of one tread and the top of the next tread. The run of each step, called the unit run, is the horizontal distance from the nosing (the front edge) of one tread to the nosing of the next tread (see "Basic Stair Dimensions"). Rise/Riser: The rise, or height of a step is measured from the top of one tread to the top of the next tread. It is not the physical height of the riser because this excludes the thickness of the tread. The number of risers, not the number of treads, is used to determine the number of steps that comprise a staircase. 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 Tread Rules of Thumb The sum of two treads plus one riser should add up to around 28" or 29" Stair step or tread "depth" or run -

Stair Riser Height Section R311.7.5.1 of the code specifies that risers must not be more than 7 ¾ inches in height and that any variation of risers within a flight of stairs must not be more than ⅜ inch. Note that dimensions here should be taken excluding carpets, rugs, or runners. Illustration: 2021 © Building Code Trainer Stair Tread Depth As a starting point in stair and step design and build you can calculate the step rise & run for a stairway with these rules of thumb. Our photo illustrates construction of a low-slope stairway located in the "Jewish Quarter" in Girona, Spain. These steps are several hundred years old, are worn, and have a bit of a slope to them. 1 IRC Requirements & How to Build Stairs Stair stringers are the notched, diagonal support boards of dimensional lumber that run along the sides and at the center of a staircase. Making stair stringers begins with correct measurements. The International Residential Code (IRC) and other building codes set requirements for how to build stairs. Rise/riser: the vertical part of the stairs, measured between two consecutive treads. Want to learn more about rises and runs? Visit the rise over run calculator. Stair stringer: it's the construction that the steps are mounted on. Angle: the inclination angle of the staircase. Landing: a platform connecting two flights of stairs.

Key Takeaways: Designing safe and comfortable stairs involves balancing the rise and run measurements, aiming for a 6 to 7.5-inch rise and 10 to 11-inch run per step. Consistency and adherence to safety.
The Total Rise should be no larger than 3835 millimeters (151 inches) between landings or floor levels. Total Run [G] - The Total Run is the horizontal length of a stair stringer. It is the Number of Steps [D] (on the stringer) multiplied by the Tread Depth [B]. Risers - The Step Height [F] is the typical height of each step. Code states that.

Using an online stair rise and run calculator is easy and simple, it does require you to take some measurements. Make sure you have an accurate tape measure or other tools for measuring when beginning this step. Many online stair calculators can give you both the rise and run, stair stringer length and stair rail angle. Call (513) 889-2492. Standard stairs must have a maximum riser height of 9.5 inches (24 cm) following OSHA 1910.25 (c) (2). IBC 1011.5.2 stipulates that the minimum and maximum stair riser heights must be 4 inches (10.16 cm) and 7 inches (17.78 cm), respectively. In groups R-3, R-2, and U auxiliary occupancies, the maximum riser height is 7-3/4.
