About this calculator
Fence Calculator is built to plan a fence line without a server round-trip. Provide your fence length and post spacing and it uses your fence length and post spacing to produce the number of posts and sections, instantly and entirely in your browser, which makes it handy for quick checks and repeat runs.
How to use
- Enter the fence line length in feet.
- Enter the spacing between posts in feet.
- Read the sections the run divides into.
- Tap Calculate to see the post and section counts.

Technical notes
Fence Calculator divides fence length by post spacing for the number of sections (rounded up), then posts = sections + 1; it does not count rails or panels.
Estimates posts and sections from the fence length and post spacing you enter; gates, rails or panels are not counted.
Nothing you type is uploaded — the calculation happens entirely on your device.
Worked example
A 30 m fence with posts every 2.5 m needs 30 ÷ 2.5 + 1 = 13 posts and 12 panels.
FAQ
How are posts and sections related?
Sections come from the length divided by the spacing, and posts are sections plus one for the end.
Does the Fence Calculator keep my entries private?
Yes. The Fence Calculator runs in your browser, so nothing you enter is uploaded or saved.
What spacing should I use?
Common post spacing is 6 to 8 feet; closer spacing adds posts but stiffens the fence.
Does it count rails or panels?
It counts posts and sections; multiply sections by your rails-per-section to get rail quantities.
