How to estimate fence materials
Subtract total gate width from the fence run, divide by maximum post spacing, and add posts for run ends and gate sides.
Before you buy
Corners, changes in direction, slopes, gate design, and post depth affect actual materials. Check utility locations and local requirements before digging.
Does it account for corners?
Not automatically. Add corner and terminal posts based on your layout.
