* The overall width of a set of outdoor stairs should be a minimum of 4 feet in a private setting, and 5 feet in a public space*. However, wider stairs are typically more inviting and can feel safer for users, particularly in crowded public spaces Building codes generally suggest at least 6 ft. 8 inches (203.2 cm) of stair headroom. Stair Width: Stair width is measured from edge to edge of each side of the tread, perpendicular to tread length

** A staircase takes up a lot of room on both the lower and upper floors, requiring careful consideration of the location**. Plan a typical staircase for a house with an 8-foot ceiling at 3 feet wide with between 9 and 10 feet of horizontal floor space. How do you calculate rise and run of stairs Stair details refer to the standard requirements for each of the various components of a flight of stairs. Regulated by building codes, stair details specify the sizes of risers and treads, stair widths, the placement of handrails and guardrails, and construction methods for fabricating stairs For example, the smallest stair that we offer is 3 feet 6 inches in diameter. 3'6 translates to 42 total inches in diameter and therefore the MINIMUM opening size that you need MUST be 44 inches x 44 inches (44x44)

Local codes typically specify stair step width limits. Usually the minimum for residences is from two feet eight inches to three feet six inches. There are no maximum widths, but stairs wider than 44 inches may require hand rails most stairs have 7 inch rises so a 12 foot high floor would have 20 steps built to reach it-most stairs have 8 to 10 inch treads so you would need about a 14 foot stringer 4.2K view Half-Turn Stairs have two straight flights with two 90Â° turns. These types of stairs are advantageous for saving space at the base where the angle is incorporated. The center of the staircase can be left open to allow for several different configurations that depend on the space When you multiply the 25-ft. length times the 4-ft. width, which includes the railing and the wall, you have a 100-square-foot area that is required for that staircase. Double those figures to account for the hall or path to go around the staircase, and you have 200 square feet for one staircase. This is the size of a single-car garage Stair runners come in many widths varying from 20 to 48 wide. The most common width is 27 for a standard staircase.

But requiring an 11â€³ unit run is controversial. Increasing the unit run even an inch or two can greatly increase the size of the staircase. With a rise of 12 feet and a unit rise of 7.2 inches, increasing the unit run from 9â€³ to 11â€³ makes the staircase two feet longer-probably 6 square feet of floor area carved out of the living room Once again this is not equally divisible by 7.5, but it yields 16 risers.

The tread depth, or horizontal step, should not be less than 10 inches. IRC also requires the slope to be not more than 30 degrees

Rise-X / 11 = 0.7535. Using simple algebra we re-arrange the formula above to read. Rise-X = 0.7535 x 11. Rise-X = 8.2 - too big.
