Decking Board Formula:
| From: | To: |
The Decking Board Calculator helps determine the number of boards needed for a decking project based on the area to be covered and the dimensions of the individual boards. This UK-specific calculator uses standard decking board measurements common in the UK market.
The calculator uses the formula:
Where:
Explanation: The formula calculates how many boards are needed to cover a specific area, accounting for the dimensions of each board. The result is rounded up to ensure you have enough materials for your project.
Details: Accurate calculation of decking boards is essential for proper project planning, budgeting, and minimizing material waste. It ensures you purchase the correct amount of materials for your decking project.
Tips: Enter the total area in square meters, board width in meters, and board length in meters. All values must be positive numbers. Standard UK decking boards are typically 2.4m long with widths varying between 90mm-150mm.
Q1: Why divide by 10000 in the formula?
A: The division by 10000 converts the board area from square meters to the correct unit for calculation with the total area in square meters.
Q2: Should I add extra boards for waste?
A: Yes, it's recommended to add 10-15% extra boards to account for cutting waste, mistakes, and future repairs.
Q3: What are standard UK decking board sizes?
A: Common sizes are 2.4m length with widths of 90mm, 120mm, or 150mm. Thickness is typically 22mm or 28mm.
Q4: Does this account for board spacing?
A: No, this calculator assumes boards are placed edge-to-edge. For proper drainage, you should account for 3-6mm gaps between boards in your final calculation.
Q5: Can I use this for composite decking?
A: Yes, the formula works for any decking material as long as you input the correct board dimensions.
