How far apart should fence posts be?
Many wood fences use a maximum post spacing of 8 ft.
Use the panel width or the product specification when it gives a smaller spacing.
| Run length | 6 ft maximum | 8 ft maximum | 10 ft maximum |
|---|---|---|---|
| 50 ft | 10 posts | 8 posts | 6 posts |
| 100 ft | 18 posts | 14 posts | 11 posts |
| 150 ft | 26 posts | 20 posts | 16 posts |
The table includes two end posts. It does not include a gate or a corner.
Calculate the post spacing
Divide the run length by the maximum spacing. If the result is not whole, increase it to the next whole number.
Add one post for a straight run. A 100 ft run with an 8 ft maximum has 13 sections and 14 posts.
The calculated spacing is 7.69 ft.
Calculate each run
Stop a run at each corner, gate, and fence end. Calculate each run separately.
This method prevents a long section at a corner. It also gives the correct quantity of line posts.
Panels and rails
For a panel fence, use the measured panel width as the post spacing. Put a post at each panel joint.
The rail length and stiffness can make a smaller spacing necessary. The Hoover Fence instruction gives 8 ft as a usual spacing for a wood fence.
Conditions that decrease spacing
A tall fence, a high wind load, weak soil, or a heavy infill can make a smaller spacing necessary.
Obey the fence-system specification and local requirements. Use the fence calculator to calculate each run.
Important information
- Use the maximum spacing in the applicable specification.
- Before you set the posts, measure the panel or rail.
- Use the specified posts at corners and gates.
