Free Tool
Fence Post Calculator
From a short side-yard run to a full Folsom Ranch corner-lot perimeter, post count drives both material cost and install time. Enter run length, spacing, and corner or end extras to estimate total posts before you order.
How this tool works
- Enter total fence length in linear feet.
- Choose post spacing and add corner or end posts beyond the standard run count.
- Review total posts and spacing summary for your layout.
Assumptions & notes
- Base formula: floor(length ÷ spacing) + 1 for a straight run.
- Corner and end extras account for gate posts, brace posts, or additional terminals not in a simple straight count.
- Spacing of 8 feet is typical for wood and vinyl; 10 feet may apply to some chain link runs.
Frequently asked questions
Do corner posts count twice?
On a continuous run, corner posts are usually included in the base count. Use corner extras only for additional brace posts, gate posts, or separate fence segments.
How many posts does a gate need?
A single walk gate typically needs two posts; double-drive gates often need three or four depending on width and hardware. Add those in the corner/end extras field.
What post spacing is best on a graded lot?
Shorter spacing (6 feet) helps panels stay rigid on stepped or sloped Folsom Ranch lots without excessive gaps at the bottom.
