Methodology
Transparent calculation
BuildMeter converts every input to a consistent internal unit, applies the selected allowance, and rounds products up to whole purchasable units.
Bays = round up(length ÷ maximum spacing). Installed rail length = fence length × rails per bay.

FAQ
Fence Rail Calculator questions
Why can actual bay width be smaller?+
Bay count is rounded up so spacing does not exceed the entered maximum.
Does this include gate rails?+
No. Estimate gate framing separately.
Can rail offcuts be reused?+
Sometimes, when connection and bearing requirements allow.
