It is acceptable and within building code guidelines to use either 2×10 or 2×12 dimensional lumber to create a set of stairs; however, a stair stringer should not be less than 3.5 inches wide at its narrowest point to provide adequate strength for the load the stairs will be supporting.

Stringer: A stair stringer is a structural member that supports the treads and risers of a staircase. Typically, there are three in a staircase: one on each side, and one in the middle. Stringers are not always visible, but can be seen on stairs with open sides. The stringers can either be cut to the shape of each step, or in some cases, are.

This example uses 5/4 x 6 decking that is 1" thick, a stair rise that is 6-3/8" and a bottom stair stringer rise that is 5-3/8". The cut line is in red. Save. Stair Treads. Notice that the stair stringer top step has a 9" run and the next step has a 10" run. The back tread for the top step had to be ripped down to fit the opening.

1 Determine the overall height of the stairs. Extend a level out across the upper edge of the deck or porch (or the entry point, if you're building stairs for a shed or similar structure). Stretch your tape measure from the bottom of the board to the ground. This will tell you exactly how high the new stairs will reach. [1]

What to Know About Cutting Stair Stringers This Old House

Stringer Length Calculator. Calculate the length of a stringer from the total rise, the number of risers and known run of one tread. The number of Risers. To see the number of risers, divide the total rise by a riser height that works for you. For instance, convert this to a decimal if you like a 7 1/2" riser. 7 1/2" = 7 + 1 ÷ 2 = 7.5 inches.

Stair Stringer. The stair stringer is a structural member installed on either side or in the center of a flight of stairs into which the treads and risers are attached. The primary function of the stringer is to provide a framework and load-bearing support for the treads and risers.. All of the stairway dimensions in the building code are.

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.. Nosing: the portion of the stair tread that overhangs the front of a riser.. Flush mount: in a standard mount, the last tread is one step below the floor level.In a flush mount, it is at the same height as the floor level.

A stringer is used to support stair treads uniformly spaced to ease the step up or down between ground and deck, deck and deck, or structure and deck. Stringers are commonly made from pressure treated 2×12 or two 2x6s fastened together along their length.

If the stair treads are set into grooves routed into the stringer, in a 2x stringer the groove depth should be 1/2 the thickness of the stringer (typically 3/4") and additional support by cleats or by gluing and end-screwing through the stringer sides into the treads is good practice.

The Stringer Length value is the minimum length of 2x12 material required to lay out the stair stringer. Total Rise [A] - The Total Rise of a flight of stairs is the vertical rise between the bottom of the first step and the top of the finished landing. The Total Rise [A] should not exceed 151 inches (3835 mm) between landings or floor levels.

The building code ( IRC, R311.7 Stairways) [Editor's note: link updated to 2021 version] is strict regarding stair layout and includes the minimum tread depth (10 inches), the maximum riser height (7 3/4 inches in the IRC, but this can vary by state), the maximum variance (typically 3/16 inch) between riser heights in a given stairway, and more.

Step 2: Establish the number of risers. Divide the height dimension by 7-3⁄4 inches (the maximum riser height allowed by building codes). That will give you a number and a decimal fraction.
