A fence estimate begins with straight runs between corners or terminals. Treating every change in direction as a new run keeps the post count and layout understandable.
Map before measuring
Sketch boundaries, buildings, slopes, utilities, trees, and gate locations. Confirm the property line through appropriate records or a survey rather than assuming an existing fence is correct.
Measure each straight run
Record horizontal distance. On steep slopes, installation method affects panel and post requirements, so note grade changes instead of relying on slope distance alone.
Separate gate openings
Deduct gate widths from ordinary panels and add gate posts and hardware separately. Gate clearance and hinge/latch geometry depend on the chosen system.
Practical takeaway
The saved run list should match a labeled site sketch. That pairing is far more useful than a single perimeter number.
