Our deck material calculator will help you to build your next deck. Take the guesswork out of purchasing the materials to build a deck by getting a deck estimate before you start your project. This can help you adjust your expectations and save time and money on your project.

Building a Deck Just Got Easier

There are many ways to build a deck. You can keep it simple with a ground level deck or build a fancy deck with stairs and multiple levels.

To keep things simple, our deck material calculator estimates materials for a ground level deck without stairs or a railing. If you need both, you can still use the calculator to estimate how much material you’ll need for the deck itself.

The variety of decking materials and variables can be overwhelming, which is why many people seek professional assistance. Our deck material calculator uses standard 2 x 6 pressure treated lumber for decking available at most hardware stores. It also assumes floor joists are 16 inches apart and 6 x 6 footers, also called stumps, are 8 feet apart and that the deck is ground level.

When using our deck material calculator, there are a few other important factors to keep in mind. These factors include:

  • Our deck material calculator will tell you the size of the joist boards necessary based on the square footage of the deck.
  • Footers should be set 6 inches deeper than the frost line for your area. This depth will determine how much concrete you need and how long your footers should be.
  • For cold climates, the frost line is around 42 inches. For warmer climates, it’s around 12 inches. Always refer to local building codes to be exact, or ask your handyman.
  • If your deck is elevated more than 12 inches, you’ll need to adjust the height of your footers to accommodate for the extra height.
  • For bearers, this deck material calculator uses two 2 x 6 boards glued together with construction adhesive.
  • If your deck is attached to your home, don’t forget to calculate the necessary flashing and anchors you’ll need to secure it. Your handyman or local hardware store should point you in the right direction based on the deck measurements in this calculator.
  • In many cases, any deck over 18 inches will require a railing and stairs to meet code. To avoid delays later on in the project, decide now to either keep your deck low to the ground or make a plan to construct a railing and stairs.

We’ve found this method to be the easiest and most reliable way to build a deck for our customers. Keep in mind, building codes vary state-by-state. If building permits are necessary in your town, be sure to secure them before starting construction on your deck.

Due to variables out of our control, Mr. Handyman wants to remind you that this calculator produces deck estimates only. You should be prepared for any changes or adjustments that come up during the construction process.
