  • Level
  • 2x12 lumber

Step-by-Step Guide

1. Measure the Height and Width of Your Deck

The first step in building deck stairs is to measure the height and width of your deck. You will need to determine the height from the ground to the top of your deck, as well as the width of the opening where you will install the stairs.

2. Calculate the Number of Steps Needed

Once you have measured the height of your deck, you can calculate the number of steps needed. To do this, divide the height of your deck by the height of each step. The height of each step should be between 7 and 8 inches.

3. Cut the Stringers

The stringers are the support structures for the stairs. You will need to cut two stringers for each set of stairs. To do this, use a circular saw to cut the stringers out of 2x12 lumber. Be sure to follow the measurements you calculated in step 2.

4. Install the Stringers

Next, you will need to install the stringers. Use wood glue and deck screws to attach the stringers to the deck frame. Be sure to use a level to ensure that the stringers are level and plumb.

5. Install the Treads and Risers

Now it's time to install the treads and risers. Cut the treads and risers out of 2x4 lumber using a jigsaw. Be sure to follow the measurements you calculated in step 2. Attach the treads and risers to the stringers using deck screws.

6. Install the Handrail

The final step is to install the handrail. Cut the handrail out of 2x4 lumber and attach it to the stringers using deck screws. Be sure to follow local codes and regulations for handrail height and spacing.
