Post spacing compared
Closer posts mean a bigger post and concrete bill. Same run, three spacings.
| Post spacing | Posts needed | 50 lb concrete bags, whole job |
|---|---|---|
| 6 ft | 141 posts | 564 |
| 7 ft | 121 posts | 484 |
| 8 ft | 106 posts | 424 |
What else matters here
Eight hundred and thirty five feet of fence is 1,822 pickets, and 424 bags of concrete is over ten tons on its own.
What this calculator assumes
- Sections are the length divided by the spacing, and posts are sections plus one. Corners and gates each add a post on top of that.
- Concrete per hole is the hole volume less the post, figured at a 4x4.
- Set posts a third of their length in the ground in frost country, and check your local frost depth before you dig.
