Estimate how many fence posts and sections you need based on total fence length and post spacing.
For a straight fence run, divide the total fence length by the post spacing to estimate the number of sections. Then add one post.
Formula: fence length ÷ post spacing = sections
Posts: sections + 1
Example: 120 feet ÷ 8 feet = 15 sections, so you need about 16 posts for a straight run.
| Post Spacing | Common Use |
|---|---|
| 6 ft | Shorter spacing or heavier fence sections |
| 8 ft | Common spacing for many wood fences |
| 10 ft | Some lighter-duty or specialty applications |
This calculator gives a simple estimate for straight fence runs. Add extra posts for corners, gates, end posts, slope changes, transitions, and changes in direction.
Use this fence calculator for backyard fences, garden fences, side yard runs, property projects, landscaping estimates, and planning material purchases.
Divide total fence length by post spacing, round up to get sections, then add one post for a straight run.
Common post spacing is 6 to 8 feet, depending on fence type and material.
No. Gates usually require additional posts, so add those separately.
Yes. Add extra posts for corners, ends, gates, slopes, transitions, and layout changes.
