Understand the estimate
Formula and assumptions
Net fence length = run length − gate widths. Sections = ceiling(net length ÷ target spacing). Each independent run needs sections + 1 posts. Rails and panels follow the section count; pickets follow net length ÷ picket pitch.

Assumptions to confirm
- Each entered run is independent and receives two end posts.
- Gate posts and gate hardware are added separately.
- Panel width or spacing is a planning target; field layout may shift.
- Corner, terminal, brace, and code requirements vary by fence system.
Label every measurement and keep exclusions visible. Add the shapes in the calculator instead of hiding them inside one total.
Worked example
Input
A 60 ft run with a 4 ft gate and 8 ft spacing, two rails per section.
Planning result
The net run is 56 ft: 7 sections, 8 line/end posts, 2 gate posts, and 14 rails.
Common package sizes
Package conventions vary by brand and region. Enter the usable coverage or yield shown on the actual product instead of relying on the name or weight alone.
- Prefabricated panels
- Loose rails and pickets
- Posts with concrete per hole
- Gate hardware kits
Frequently asked questions
Why are gate posts separate?
Gates usually need stronger terminal posts and dedicated hardware, so the shopping list keeps them visible.
Does the tool place corners?
Treat each straight run as independent. Add a new run at every corner so its end posts are counted.
Does this check bylaws?
No. Confirm height, setbacks, utility locates, permits, and pool-barrier rules locally.
