Example Calculation

Let’s say you are planning a deck that is 20 feet long and 15 feet wide. You’re using Trex boards that are 6 inches wide and 12 feet long. Here’s how the calculator works:

  • Deck Area = 20 ft × 15 ft = 300 sq ft
  • Board Area = 6 in ÷ 12 × 12 ft = 0.5 ft × 12 ft = 6 sq ft per board
  • Total Boards Needed = 300 ÷ 6 = 50 boards

With a simple click, the Trex Decking Calculator tells you that you’ll need 50 boards to complete your deck. No more guesswork, no wasted materials.

Tips for Using the Decking Calculator

To get the most accurate results and avoid project delays, keep the following tips in mind:

  • Measure Twice: Always double-check your deck measurements before entering them.
  • Account for Gaps: Trex boards require spacing for expansion, usually 1/8 inch. Add a small buffer if needed.
  • Consider Waste: For projects with complex shapes or angles, it’s wise to order an extra 5–10% of boards.
  • Uniform Boards: Ensure all boards are the same width and length for accurate calculations.
  • Update Measurements: If your deck design changes, recalculate before ordering.
