Planning a new Trex deck? Our free Trex Deck Board Calculator makes it easy to estimate how many deck boards you’ll need before you order materials.
Simply enter your deck’s total square footage, and the calculator will instantly estimate the number of Trex decking boards required if you choose 12-foot, 16-foot, or 20-foot deck boards.
Since all standard Trex deck boards have a finished width of 5.5 inches, the calculator provides a quick and accurate estimate to help you compare board lengths and determine which option may work best for your project.
Whether you’re a homeowner planning a backyard deck or a contractor preparing an estimate, this tool can save time during the planning process. While every deck layout is different and additional material may be needed for picture framing, stairs, angled patterns, or waste, this calculator provides a solid starting point for estimating your decking needs.
