Formula & Methodology
Our calculator uses the following formula to estimate the amount of decking material needed:
Material Needed (sq ft) = Length (ft) x Width (ft)
We also factor in waste allowance based on the selected material:
- Cedar: 10% waste
- Trex: 5% waste
- Composite: 7% waste
Real-World Examples
Example 1: Small Deck
A 10ft x 12ft deck using Trex composite material would need approximately 126 sq ft of material, including waste.
Example 2: Large Deck
A 20ft x 16ft deck using cedar would need approximately 352 sq ft of material, including waste.
Example 3: Unique Shape
A 15ft x 10ft deck with a 5ft x 5ft cutout using composite material would need approximately 150 sq ft of material, including waste.
