Formula
Sections = usable fence length ÷ post spacing, rounded up. Posts equal sections plus one for a straight run, before corners and gates.

CALCULATOR GUIDE
How to use the Fence Material Calculator
Estimate fence panels, posts, rails, gates and post-hole concrete from the total fence run and spacing.
Worked example
A 100 ft fence with one 4 ft gate and 8 ft spacing needs 12 panel sections across the remaining 96 ft.
Assumptions and limits
Corners, slopes, terminal posts, gate hardware, local setbacks and frost-depth requirements can change materials.
Frequently asked questions
How many fence posts do I need?
For a straight run, posts usually equal the number of sections plus one. Add appropriate posts for corners and gates.
Should gate width be subtracted?
Yes. The calculator subtracts gate openings before estimating ordinary fence sections.
