How it's calculated
Bays = fence length ÷ maximum spacing, rounded up. Posts = bays + 1. Rails = bays × rails per bay.
Calculations use consistent units for your selected measurements. Whole purchase quantities are rounded up.
What this estimate includes
Includes one post at each end. Gates, corners and stepped sections need their own counts. Spacing is user-specified.
