How gates and corners change a fence material count

Understand why one total length is not enough for a fence order.

Short answer: For two gates, break the run into three solid spans. Round bay counts inside each span, add both gate-boundary posts, then count a shared corner only once if another run uses the same physical post.

Swipe the diagram sideways to see every label. The full calculation is written below it.

A 96-ft run has 4-ft gates at 20–24 ft and 60–64 ft. Solid spans are 20, 36, and 32 ft. With a maximum bay of 8 ft, round each span separately for 12 bays and 15 distinct post positions.

Divide the run at every opening

Measure from the run start to gate 1, between gates, and from gate 2 to the end. In the adjustable 96-ft example, two 4-ft gates start at 20 ft and 60 ft, leaving 20, 36, and 32 ft of solid fence. Do not divide the combined 88 ft as though it were one continuous span.

Round bays by solid span

At an 8-ft maximum, those three spans require 3, 5, and 4 bays: 12 in total. Count each run end and both sides of each gate as separate boundary posts, then add only the interior bay posts. This example yields 15 distinct post positions. Moving a gate can change the rounded bay count while total solid length stays the same.

Reconcile the physical layout

The fence planner draws all nonoverlapping gates on a run and reports rails and pickets separately. If another run meets at a corner, count that common physical post once. Premade panels, gate hardware, bracing, post size, and local conditions need a product and site check; the arithmetic does not specify a safe gate structure.

Hypothetical worked example

Worked two-gate layout: on a 96-ft straight run, 4-ft gates span 20–24 ft and 60–64 ft. The solid spans are 20, 36, and 32 ft. At an 8-ft maximum bay, round each span separately: 3 + 5 + 4 = 12 bays. Six span-boundary posts plus nine interior bay posts yield 15 distinct posts. Gate hardware and any shared corner on another run are separate checks.

Which situation matches your project?

Either gate moves but its width stays the sameRecalculate all three solid spans; their rounded bay counts can change even when total covered length does not.Test both gate positions →You are using premade panelsCheck the panel’s actual fit and whether short bays can be cut before accepting the rounded panel count.Check panel bays →Two runs meet at a cornerCompare their end positions on the site sketch and subtract one shared post only when they are the same physical post.Check the shared corner →

Limit to check: Gate frame, hinges, latch, bracing, and post design are product-specific; the material count is not a structural gate specification.
