It is the best option to use pre-cut stringers. You can easily avail of it from builder’s support stores as they are readily available in the standard size. Choose to make your stringers only when you need the stairway to be steeper.

  • measure the height and length of the stringers you need and get them from the market. You can also customize the longer stringers according to your requirements.
  • For cutting a stringer to size, cut it at the bottom step so that is not as high as the others. The bottom steps can be much less high.

It is equally important to realize the position and the angle where your staircase will end and start. Draw a line from the edge of your deck down to the ground at a 40-degree angle while making a mark for a point at the end of the staircase. 

  • Make sure that the 40-degree slope starts at the bottom of the support beam where you are going to fix the stringers.

Place a Straight Board on the Deck:

Finally, position the board on the staircase and extend it so that it is directly above the bottom of the stairs that acts as a landing spot.

  • You can put board slopes upward toward the landing spot and level it with shims.
  • Measure the ground to the board and write down measurements for the material to be purchased.

To make it simple, consider an example. If your total rise was 60 inches, divide that number by 7. You will get an answer of 8.57. Round up the number to get 9. Use 9 steps for the deck. Moreover, note down this number to use in your calculations during construction.

Divide the total rise by the approximate number of stairs to find the rise of each step. You must also use tread boards that are at least 36 inches long and 10 inches deep. These boards create the part of the stair that you step on.

Calculate the Length of the Stringers to Know the Length of the Staircase:

You will find stringers either of saw-toothed or stair-shaped notches cut into boards. These broads run diagonally along the staircase. They prove very beneficial in supporting the staircase. All you need to do to find their length is add together the square of the run and the square of the rise. Find the square root of the answer and multiply it by the number of steps. You will find the actual length of the stringers you’ll need. 

For Example, for a tread that is 10 inches, square 10 by multiplying the number by 10. You will get 100. If your rise is 7 inches, square that number by multiplying it by itself to get 49. You must now add 100 to 49 You will get 149. Find the square root of 149. The answer will be 12.206. Finally, multiply your answer with the number of steps that you have to find the total length of your stringers.
