Wood & boards
Fence Calculator
Your measurements : length, board width, gap between boards. Your estimate : boards, posts / studs, actual equal spacing.
How the calculation works
Fence Calculator
Boards = round up((Length + Gap between boards) ÷ (Board width + Gap between boards) × (1 + Waste allowance / 100)); Posts / studs = round up(Length / Maximum center-to-center spacing) + 1Before you order
- Use the coverage, yield and dimensions printed on your product. Waste allowance is adjustable; real cuts and site conditions may change the order.
- Planning estimate only. This is not a structural design, a safety approval or a local code check.
