Example Deck Calculation
Let’s look at a practical example.
Deck Length: 20 feet
Deck Width: 12 feet
Board Width: 6 inches
Board Spacing: 0.25 inches
Price per Board: $15
Step 1: Deck Area
Deck Area = Length × Width
20 × 12 = 240 square feet
Step 2: Board Coverage
Board width plus spacing determines how much area each board covers.
Step 3: Boards Needed
The calculator determines how many boards are required to cover the deck width.
Example result: 24 boards needed
Step 4: Total Cost
Total Cost = Boards Needed × Price per Board
24 × $15 = $360
This estimate helps you prepare your budget before purchasing materials.
