ACRYFIN Deck COATINGS

Building stairs for your deck is often considered “the most difficult part of” the construction project. Having the right calculations before getting started can make the task a lot easier.

To simplify the process, we’ve created this deck stair calculator to help you determine the correct measurements needed to carry out your project. Once you’ve calculated the number of steps, you’ll then need to know how to build stairs for your deck.

What Are the Parts of a Deck Staircase?

Knowing the lingo behind the parts that make up a staircase can go a long way toward taking accurate measurements and simplifying the process.

The key components of a set of deck steps are

  1. Treads are horizontal boards that create the footing area for each step.
  2. Risers are boards that cover the vertical distance between stair treads.
  3. Stringers are the notched 2×12 boards that provide structural support for the treads and risers.
