Free Tool
Fence Post Calculator
From a narrow Rocklin side yard to a Loomis acreage boundary, post count drives both material cost and install time. Enter run length, spacing, and corner or gate 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 side-yard gate need?
A single walk gate typically needs two posts, often oversized since side-yard gates on narrow Rocklin lots get daily foot traffic. Add those in the corner/end extras field.
What post spacing is best for taller HOA panels?
Shorter spacing (6 feet) helps taller privacy panels resist wind load and stay straight without excessive bowing between posts.
