- When building deck stairs you will need to determine the total height of the deck at the stairs. This is the change in elevation from the top of the deck to where you expect the stairs to land. Place a level straight out from the deck and measure to the ground or landing using a tape measurer.You will also need to establish the tread depth and riser height for each step. The minimum tread depth is 10 and the maximum riser height is 8.In most cases this will be a 7-1/2 rise and 10-1/2 run. This will allow you to use two deck boards for each tread with a 1/2 reveal.Once you have determined the total stair height, tread depth, and riser height you can plug the numbers into the decks.com stair stringer calculator to find the stringer length, stair projection, and the angle of the stairs.lace a level straight out from the deck and measure to the ground or landing using a tape measurer.

How to Measure for Stairs Use a calculator to calculate the stair riser length or the number of steps you'll need. Divide the height from the first floor to the top of the second floor by a predetermined height of your choice for the riser. The typical height of a riser is 6 or 7 inches (15 to 17.5 cm).

How to Install New Stair Treads and Risers 1. 1  Your old treads and risers will be put on with either nails or screws. 2  Once done measure your riser first. 3  Also measure top to bottom.  If they are out of square you will have to use a adjustable square and then transfer that to the tread or 1  riser. Put a nail in the top and bottom being sure to nail into the stringers.

Tread and Rise Combinations Chart It’s important to have the right ratio of tread to rise to make going up and down safe and easy. In general, the smaller the rise, the bigger the tread. For the most part you should choose what’s comfortable for you but usually outdoor steps have a rise of 5 1/2 to 7 inches and a tread of 12 to 18 inches.ou’ll find the tread width in the column on the left and the rise height in the column on the right. You’ll notice an 18 inch tread can have either a 4 or 4 1/2 inch rise — each fits the equation so the choice is up to you.

What size of wood do I need to build stair stringers? I am building a set of stairs that is going to a platform that is only about 4 ft high. I am about to trace them out on the wood and assumed that I should use 2x10 wood but I'm second guessing myself and thinking maybe I should use 2x12 wood for the stringers.ou should use a 2x12 if you are cutting them yourself. If you have never cut your own stringers, I would suggest getting precut stair stringers from your local lumber yard or home center.

- For this example, since the deck stairs land on the ground, the thickness of the finish flooring at the lower landing is zero. In this case, you would just subtract off the thickness of the tread material since clearly there isn't any finish flooring like carpeting or hardwood floor at the base of the stairs. Assuming you will not be adding a top riser board, the edge of the deck or the header joist will serve as the top riser. As such, you will need to make a second adjustment as you layout the stairs. You will need to subtract off the thickness of the riser boards from the top tread run.

- As for number of stringers, in my town you would need at least 4 stringers for a 48 inch wide step for an outside stair. This refers to cut stringers, not solid, I just built a set of stairs for my deck, I used cut stringers, 42 inch wide steps, needed four stringers.Each step was 6 inch rise, 12 inch tread. 12 to 1 slope would indeed be very flat, if you go with 6 inch rise per step you are going to need 6 steps for a 42 inch elevation difference, and your stringer would be about 6 feet long if you went with a 12 inch tread.

- 1 When building an outdoor stairway, they are typically cut from the same material as the upper floor deck or porch–5/4 pressure-treated pine or 2-thick lumber.  Risers (Fig. 2) are the vertical members at the back of each tread. 1 surfaced boards (3/4 net thickness) are the most common material used.

Oversized Steps on the Deck The rule of thumb for step dimensions is that the combined depth and height work best when they are closest to a total of 18 inches. So, if your steps are 10 inches deep, 8 inches high is the optimum riser height. For oversized steps, the depth should be increased, with the height of each step being reduced.If the tread is 12 inches deep, the riser should be close to 6 inches. The minimum height for any step should be at least 4 inches. Determine your optimum step depth and subtract it from 18.Divide the height of your deck by the answer. Add any remainder to the bottom step.f the tread is 12 inches deep, the riser should be close to 6 inches. The minimum height for any step should be at least 4 inches. Determine your optimum step depth and subtract it from 18. Divide the height of your deck by the answer. Add any remainder to the bottom step.

Stair Gauge Jig The stretcher arms can move in and out depending on the width of the stair case (I’d make this jig to go to at least 50″ wide). The jig is best made out of a stable hardwood like Maple. It’s very important that the ends of the “pads” are straight. The beveled edge allows for easier site lines and the ability to mark the skirts if necessary close to the working edge. To use the jig simply place the jig on the stair stringers with the back of the pad tight to the back of the stringer. Rotate the pads until they are both tight to the skirt board. This locks into place the relative angle from one side to the other. It’s very important that both pads be tight to the back of the tread location. Next you set the jig on the tread material and transfer the cut lines on each end. Once you cut the tread it will fit perfectly against the skirt.

- The riser height should be 8.25 inches (21cm) or lower. The nosing protrusion length should be 1.25 inches (3.2 cm) or lower to prevent tripping on the nosing. The headroom is recommended to be 6 feet and 8 inches (203 cm) or higher. The stair width is recommended to be 35 inches (89cm) or longer. The height of the handrail, measured from the nose of the tread, is recommended to be between 34 and 38 inches (86 to 97 cm). The comfortable size of handrail diameter is between 1.25 and 2.68 inches (3.2 to 6.8 cm). Doors are normally not allowed to swing over steps.

How to Build a Deck: Wood Stairs and Stair Railings 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.

- These stringers are made from 2X10s resulting in not enough wood between the back of the stringer and the tread/riser joint. They need to be made from 2X12's. I have to completely rebuild my stairs to pass inspection now. A huge loss of time and money as HD won't give the dimension of this most critical area.

Stair Treads All of our treads are 11 1/2″ wide and 1 thick. All of our treads allow for a 1 1/2″ overhang over the riser. This overhang allows for a 3/4″ cove underneath the overhang. The size of your tread is the full coverage of the “run” from the wall or edge of the riser to the outside edge of the riser on the other side.

Building and Installing Deck Stairs For example, a total estimated rise of 52 1/2 inches divided by 7 3/4 inches equals 6.77, which rounds up to seven risers. I subtract one to get the number of treads (unless the top tread is an extension of the deck surface, there is always one less tread than there are risers).

- 7. Determine how many stringers you will need. To prevent your steps from sagging or bowing as you step on them, a wide staircase will need plenty of stringers underneath to keep it evenly supported. For safety reasons, the stringers should be spaced between 16 inches (40.6 cm) and 4 feet (121.9 cm) apart. So, if your riser is 7 inches (17.8 cm) tall, your tread should be anywhere from 9 to 11 inches (23 to 28 cm) long. 2  This makes the treads long enough to comfortably fit the average foot on and high enough to make stepping easy.
