What Is the Formula to Order Decking Planks for a Designated Area?

September 22, 2016

Calculating material requirements is outlined in our Decking Installation Guide. Let's walk through this process.

Calculating Material Requirements

Step 1: Determine Square Footage

To determine how much TimberTech decking material you will need, start by calculating the square footage of your deck surface by multiplying length by width.

Step 2: Determine Plank Length

Once you know this number, divide it by the numbers provided below for:

  • 12' planks
  • 16' planks
  • 20' planks

Step 3: Divide by Plank Length

Once you know the square footage number, divide below by:

  • 5.5 for 12' planks
  • 7.3 for 16' planks
  • 9.1 for 20' planks

When calculating the amount of decking you will need, it’s recommended that you add roughly 10% to the total for a scrap factor.
