How to measure your fence line
- Measure the total run length along the fence line (not the diagonal).
- Mark corners and gate openings; treat each straight run separately.
- Confirm local requirements for post spacing and depth (frost line).
Assumptions to double-check
- This is a straight-run estimate; gates/corners can increase post count.
- Panel systems vs picket systems differ—confirm how your product is sold.
- Slopes may require stepping or racking, which can change counts.
Buying tips
- Confirm whether panels are 6 ft or 8 ft and match your post spacing.
- Plan for gate hardware and additional posts for corners/ends.
- Order a little extra for damaged pieces and future repairs.
