Are stair stringers 2×10 or 2×12?
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.
How do you calculate slope of stairs?
Slope of staircase is calculated by trigonometric formula that is Tanθ which is equal to ratio of opposite to adjacent in a right triangle such as Tanθ = opposite/adjacent, and θ = tan^-1 (opposite/adjacent), and this value of theta (θ) will give us slope of staircase in degrees.
How many step stringer do I need?
If cut stringers are used in the stair construction, then at least three stringers are required. Cut stringers should be spaced no more than 18 inches on center. For example, a 36-inch-wide stairway should have three stringers. If the stairway is wider than 36 inches, four stringers should be installed.
How do I calculate how many steps I need for stairs?
Determining the Rise
You divide the height by 7 inches; if, say, the floor-to-floor distance is 8 feet, 10 inches (or 106 inches), then you’ll need 15 treads (106 divided by 7 equals 15.14). Next, you divide the height by the number of treads (15 into 106), producing the exact tread height (7.06 inches).

How many steps is a 5 foot high deck?
Using these measurements as a starting point to calculate actual step dimensions and how many stairs you’ll need using the height of your deck. For example, if your deck is 5 feet (60 inches) from the yard, and you want steps at 7 inches maximum, divide 60 by 7 to get 8.57 stairs.
How many stringers do I need for deck stairs?
Deck Stair Basics
Deck stairs are typically made from 2 x 12 stringers spaced about 12 to 16 inches apart. They rest on a solid foundation and are attached to the deck with hangers. They have risers (also called toe kicks), treads and railings. The stairs should be at least 36 inches wide.
What is a comfortable step height?
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.
How far can a 2×12 stair stringer span?
6 feet
A 2×12 stringer has a maximum unsupported span of 6 feet. These stairs (7) are likely to deflect and cause the stringers to either pull loose from the framing or shear along the grain.
What size board do I need to make a stair stringer?
Stringers should always be cut from 2x12s. Notching smaller stock doesn’t leave enough wood to safely carry the loads of a stair. When ordering stringers, allow about 14 inches of stringer length for each step. Look for straight stock with as few knots as possible.
What size timber should I use for stair stringers?
300 x 50 mm
For stringers: 300 x 50 mm DAR/dressed-all-round selected native hardwoods, selected plantation pine, selected to provide relatively straight grained, clear pieces. For cleats: 75 x 38 mm DAR, cut to length to suit width of treads (refer to item No. 1 0).
