1. What is a Timber Decking Calculator Australia?

Definition: This calculator estimates the volume of timber required and number of decking boards needed for Australian decking projects.

Purpose: It helps homeowners and builders accurately plan materials for deck construction, minimizing waste and cost.

2. How Does the Calculator Work?

The calculator uses two formulas:

Where:

• \( V \) — Volume of timber (cubic meters)
• \( L \) — Length of deck (meters)
• \( W \) — Width of deck (meters)
• \( T \) — Thickness of boards (meters)
• Board Width — Width of individual decking boards (meters)
• Spacing — Gap between boards (meters)

Explanation: The first formula calculates total timber volume, while the second determines how many boards are needed accounting for spacing.

3. Importance of Accurate Decking Calculation

Details: Proper calculation ensures structural integrity, compliance with Australian building codes, and optimal material usage.

4. Using the Calculator

Tips: Enter deck dimensions in meters, board thickness (default 90mm), board width (default 140mm), and spacing (default 5mm). All values must be ≥ 0.

5. Frequently Asked Questions (FAQ)

Q1: What's the standard board size in Australia?
A: Common sizes are 90x19mm or 140x22mm, but always check with your supplier.

Q2: Why include spacing in calculations?
A: Spacing allows for wood expansion and drainage, typically 3-5mm in Australian conditions.

Q3: How do I convert mm to meters?
A: Divide mm by 1000 (e.g., 90mm = 0.09m).

Q4: Does this account for joists and bearers?
A: No, this calculates decking boards only. Additional framing materials must be calculated separately.

Q5: Should I round up the number of boards?
A: Yes, the calculator automatically rounds up to whole boards to ensure complete coverage.
