1. What is the Decking Calculator?

The Decking Calculator from Narangba Timbers helps estimate the number of decking boards required for your project, accounting for necessary waste percentage to ensure you purchase adequate materials.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ N = \lceil \frac{\text{Deck Area}}{\text{Board Length} \times \text{Board Width}} \rceil \times (1 + \frac{\text{Waste Percentage}}{100}) \]

Where:

\( N \) — Number of boards needed
\( \text{Deck Area} \) — Total area to be decked (m²)
\( \text{Board Length} \) — Length of individual board (m)
\( \text{Board Width} \) — Width of individual board (m)
\( \text{Waste Percentage} \) — Additional percentage for cuts and waste (%)

Explanation: The formula calculates the base number of boards needed, applies ceiling function to round up to whole boards, then adds the specified waste percentage.

3. Importance of Accurate Decking Calculation

Details: Proper calculation ensures you purchase enough materials for your project while minimizing waste and avoiding costly additional trips to the timber supplier.

4. Using the Calculator

Tips: Measure your deck area accurately in square meters. Use actual board dimensions from your chosen product. Typical waste percentage is 10-15% for simple layouts, 15-20% for complex patterns.

5. Frequently Asked Questions (FAQ)

Q1: Why include a waste percentage?
A: Waste percentage accounts for cutting waste, damaged boards, pattern matching, and future repairs.

Q2: How do I measure deck area accurately?
A: Measure length and width of the deck space, multiply to get area. For irregular shapes, break into rectangles and sum the areas.

Q3: What's a typical waste percentage?
A: 10-15% for straight layouts, 15-20% for diagonal patterns, and 20-25% for complex designs with many cuts.

Q4: Should I buy extra boards beyond the calculated amount?
A: Yes, it's recommended to purchase 1-2 extra boards beyond the calculated amount for future repairs and replacements.

Q5: Does this calculator account for board spacing?
A: No, this calculator assumes tight board placement. For spaced decking, you may need slightly fewer boards.
