Hypothetical planning example
Gate position and the final bay
Moving a 4 ft gate on the same 60 ft run keeps total fill constant while the two fill segments change.

Question this answers
Why does sliding a gate along one run change the leftover panel bays on each side?
Assumptions
- One 60 ft straight run
- One 4 ft single gate (default fixture offset 10 ft from run start)
- Panel system with the same module as other panel fixtures
- Same total fill length when the gate moves; segment lengths change

Calculator result
Derived with the shared materials engine — not hard-coded in this page.
- Total fence length: 60 ft
- Fill length (excludes gate openings): 56 ft
- Posts: 10 total (end 2, line 6, corner 0, gate 2, terminal 0, structure 0)
- Concrete bags (project rounding): 62
- 6 full panels, 8 panels to buy (cut bay 1: pitch remainder 2 ft, clear space 1 ft (short); cut bay 2: pitch remainder 4 ft, clear space 4 ft (valid))
- Fill segments on the gated run: 10 ft + 46 ft

What this result means
- Gate location is a layout decision — not only a hardware SKU.
- Remainder bays are computed per fill segment after the opening is removed.
- Open the planner example to try another offset and watch both sides update together.
What this scenario shows
- Fill split into segments on either side of the gate
- Total fill staying constant when only gate offset changes
- Why final-bay remainders can differ by segment even when purchases look similar overall
What this does not prove
- Does not prove swing clearance past obstacles or code-required gate widths.
- Does not auto-optimize “best” gate placement for you.
- Hypothetical inputs only.
