Turn a deck footprint into a first-pass material list and rough material budget.
Estimated Material Cost

Enter the deck dimensions and framing assumptions to estimate a first-pass shopping list.
Tap an example to prefill the calculator with sample values.
Backyard platform deck
16 ft x 12 ft at 16 in joist spacing
A typical mid-size project where decking, joists, beams, and posts all matter to the material stack.
Result: A modest deck can still add up to dozens of boards plus a meaningful framing and hardware cost
Raised entertainment deck
20 ft x 14 ft at 3 ft height
A larger footprint where more deck rows, more joists, and a bigger beam run quickly increase the material count.
Result: The material list expands faster than the footprint suggests once you account for framing and waste
High deck with extra support
18 ft x 16 ft and over 8 ft high
Shows why a taller deck often needs more support lines and posts than a low platform.
Result: The extra support line and denser spacing move both count and cost materially higher
