Fence Post Installation Guide
Post Hole Requirements
- • Dig holes 1/3 the height of the above-ground post
- • 6-foot fence: 2-foot deep holes
- • Hole diameter: 3× post width

- • Use fast-setting concrete for convenience
Post Spacing
- • Standard spacing: 6-8 feet on center
- • Match panel widths when possible
- • Closer spacing for heavy or tall fences
- • Gate posts need larger diameter or bracing
- • Corner posts require additional support
Fence Installation Process
Step 1: Planning & Layout
- • Check property lines and local building codes
- • Call 811 to mark underground utilities

Frequently Asked Questions
How deep should fence posts be?
Generally, post holes should be 1/3 the height of the above-ground portion. For a 6-foot fence, dig 2-foot deep holes.
How much concrete do I need per post?
Typically 1-2 bags of fast-setting concrete per post, depending on post size and fence height. Heavier fences need more concrete.
Do I need a permit to build a fence?
Requirements vary by location. Check with your local building department. Most areas have height restrictions and setback requirements.
What's the best fence for privacy?
Solid wood panels, vinyl privacy fence, or composite materials provide the best privacy. Consider height restrictions in your area.
