A planning estimate, not a contractor takeoff. Add a little waste and confirm against local building code.

How it works

  1. 1

    Enter the run

    Add the total length and the height of the aluminum fence.

  2. 2

    Set the panel width

    Posts sit one panel apart, so the panel width is your post spacing, usually 6 ft.

  3. 3

    Get the count

    See panels, posts and concrete, with each gate replacing a panel.

Frequently asked questions

How are aluminum panels counted?
Aluminum fencing ships as preassembled panels, one filling each section between posts, so panels equal the number of sections. Each gate replaces a panel, so the count drops by one per gate.
What post spacing do aluminum panels use?
Use the width of the panels you are buying, most often 6 ft. The post count follows from that spacing, with one extra post at the closing end.
Do aluminum fences need concrete?
Most residential aluminum posts are set in concrete for stability. The calculator sizes a hole per post and totals the bags for the whole run.
How accurate is the aluminum fence estimate?
The panel and post counts are exact for a straight, level run. Slopes, corners and stepped sections can change the post count, so use it as a close estimate and check against the manufacturer’s layout for your kit.
