What is a Decking Materials Calculator?
A decking materials calculator is a tool that helps you estimate the quantity of materials required for a new deck. It calculates the number of decking boards, framing joists, and essential hardware based on your deck's dimensions and chosen board pattern. This provides a basic shopping list to help you start your project with confidence.
How to Use the Decking Calculator
- Enter Deck Dimensions: Input the width and length of your deck in feet.
- Select Board Width: Choose the actual width of your deck boards (e.g., 5.5 inches for a standard 6-inch board).
- Choose Board Pattern: Select whether you will lay the boards straight or on a diagonal, as this affects the required waste factor.
Understanding Your Deck Material List
This calculator provides a simplified shopping list for the main components of a basic rectangular deck frame and surface.
- Decking Boards: This is the estimated number of surface boards needed to cover your deck area, including a waste factor. The result is given in both the number of boards and the total linear feet.
- Framing: This is a rough estimate of the number of joists and support posts needed for a standard deck. It assumes 16-inch on-center joist spacing and posts every 8 feet.
- Hardware: This provides a very basic estimate for essential hardware like joist hangers and deck screws. You will need additional hardware like bolts, anchors, and fasteners.
This is a Simplified Tool
This calculator is for quick material estimates for the deck surface and basic frame ONLY. It does not include materials for beams, stairs, railings, or the concrete foundation. For a full project budget, use our detailed Deck Cost Calculator.
