Timbertech Decking Calculator

Building a TimberTech deck requires precise planning to ensure that you purchase the right number of boards, fasteners, and accessories while staying within budget. A TimberTech Decking Calculator simplifies this process, providing accurate material estimates and helping homeowners, contractors, and DIY enthusiasts plan their decking projects efficiently.

What Is a TimberTech Decking Calculator?

A TimberTech Decking Calculator is an online tool designed to:

• Estimate the number of decking boards required
• Calculate the total length of boards for a given deck size
• Determine the quantity of fasteners, screws, or clips needed
• Assist in project cost estimation

This tool is especially useful because TimberTech composite decking comes in standard board sizes, and miscalculations can lead to over-purchasing or insufficient materials.

Key Inputs for the Calculator

1. Deck Dimensions – Length and width of the deck area.
2. Board Width – Standard TimberTech board widths, often 5.5 inches or 6 inches.
3. Board Length – Standard lengths like 12, 16, or 20 feet.
4. Board Spacing – Recommended gaps for drainage and expansion, usually 0.125 inches (1/8 inch).
5. Fastener Type – Hidden fasteners or screws per board length.

Formulas Used in the Calculator (Plain Text)

1. Number of Boards Needed

Number of Boards = Deck Width ÷ (Board Width + Gap)

2. Total Board Length

Total Board Length = Number of Boards × Deck Length

3. Fasteners Required

Number of Fasteners = Total Board Length ÷ Board Section Length × Fasteners per Section

4. Waste Factor

• It’s recommended to add 5–10% extra boards for cuts and errors.
  Adjusted Boards = Number of Boards × 1.05 to 1.10

5. Cost Estimation

Total Cost = (Number of Boards × Board Price) + (Number of Fasteners × Fastener Price)

How to Use the TimberTech Decking Calculator

Step 1: Enter Deck Dimensions

• Input the length and width of the deck in feet or meters.

Step 2: Select Board Specifications

• Choose the board width, board length, and gap between boards.

Step 3: Specify Fastener Type

• Select hidden fasteners, screws, or clips. Enter quantity per board length if required.

Step 4: Include Waste Factor

• Optionally, add 5–10% extra for cutting errors and adjustments.

Step 5: Calculate

• Click calculate to get:
  • Total number of boards needed
  • Total board length
  • Number of fasteners
  • Estimated material cost

Step 6: Review and Adjust

• Check the results and adjust board lengths or spacing if needed to optimize materials and reduce costs.

Example Calculations

Example 1: Small Deck

• Deck dimensions: 12 ft × 14 ft
• Board width: 5.5 inches (0.458 ft), Gap: 0.125 in (0.0104 ft)
• Boards required: 14 ÷ (0.458 + 0.0104) ≈ 29 boards
• Total board length: 29 × 12 ft = 348 ft
• Fasteners: 4 per foot → 348 × 4 = 1,392 fasteners

Example 2: Large Deck

• Deck dimensions: 20 ft × 30 ft
• Board width: 6 inches (0.5 ft), Gap: 0.125 in (0.0104 ft)
• Boards required: 30 ÷ (0.5 + 0.0104) ≈ 59 boards
• Total board length: 59 × 20 ft = 1,180 ft
• Fasteners: 4 per foot → 1,180 × 4 = 4,720 fasteners
• Add 5% waste → 59 × 1.05 ≈ 62 boards
