Example:
- Width = 12 feet
Step 3: Enter Board Width
Provide the width of the decking board in inches.
Common sizes include:
- 5.5 inches
- 6 inches
The calculator uses this value to estimate board coverage.
Step 4: Enter Waste Factor
Specify the percentage of extra material you’d like to include.
Common waste factors:
- 5% for simple decks
- 10% for standard projects
- 15% or more for complex designs
Step 5: Click Calculate
The calculator instantly displays:
- Deck area
- Boards needed
- Boards including waste
Step 6: Review Results
Use the calculated values to determine how much lumber to purchase.
Step 7: Estimate Material Cost
Switch to the Cost Estimator section.
Enter:
- Total boards needed
- Cost per board
Click Calculate to view the estimated project cost.
Understanding the Results
The calculator provides three important outputs.
Deck Area
This represents the total surface area of the deck in square feet.
Example:
- Length = 20 ft
- Width = 12 ft
Deck Area:
240 square feet
Boards Needed
This is the estimated number of boards required to cover the deck without waste.
Waste Included
This value includes the selected waste percentage and represents the recommended purchase quantity.
Total Cost
The cost estimator multiplies:
Total Boards × Cost Per Board
This provides an approximate material budget.
Practical Example 1: Backyard Family Deck
Imagine you want to build a deck behind your home.
Project Details:
- Deck Length: 16 feet
- Deck Width: 12 feet
- Board Width: 5.5 inches
- Waste Factor: 10%
The calculator will determine:
- Total deck area
- Number of boards required
- Additional boards for waste
You can then purchase the correct amount of material without unnecessary overspending.
Daily Life Benefit
Homeowners can create accurate budgets before visiting a lumber supplier, reducing unexpected expenses.
Practical Example 2: Contractor Project Estimate
A contractor is preparing a quote for a client.
Project Details:
- Deck Length: 24 feet
- Deck Width: 18 feet
- Board Width: 5.5 inches
- Waste Factor: 12%
After calculating the required boards, the contractor enters:
- Boards Needed: 110
- Cost Per Board: $18
The calculator instantly estimates total material costs.
Daily Life Benefit
Contractors can generate faster and more accurate project estimates for customers.
