Aluminum Fence Panel On-Center Spacing Calculator

Pick your GradePanel WidthPost Size. We’ll auto-fill the post-to-post “On Center” spacing measurement. This measurement is a combination of 1 aluminum fence panel connected to 2 (line, corner, end) posts which helps in determining how many sections you will need to purchase. We recommend rounding up your fence panel quantities for each fence run so that you have enough product to complete your barrier.

On-Center Measurement
This shows the typical center-to-center spacing for your selection.
