How this calculator works
Estimate the number of fence sections and posts for a straight or combined fence run. The result keeps spacing assumptions explicit.
Net fence run = total run − gate widths. Sections = ceiling(net run ÷ post spacing). Posts = sections + 1, with additional gate posts as needed.
Example
A 120 ft run at 8 ft spacing needs roughly 15 sections before accounting for gates and layout changes.
How to get a better estimate
- Corners, ends and gates often need stronger posts.
- Actual panel width may control spacing more than a nominal target.
- Call utility-location services before digging.
What the result means
The result is a planning estimate. Dimensions, coverage, density, packaging and installation conditions vary by product and project. For purchasing, compare the result with the exact product label or supplier specification. For structural, electrical, code-regulated or safety-critical work, use an appropriately qualified professional.
