Frequently Asked Questions
How far apart should fence posts be?
Standard fence post spacing is 8 feet on center. For taller fences (over 6 feet) or high-wind areas, use 6-foot spacing for added strength.
What size posts should I use?
Use 4x4 posts for fences up to 6 feet tall. For taller fences, use 6x6 posts. Corner and gate posts should be one size larger.
How deep should fence posts be buried?
Bury posts at least 1/3 of their height, or minimum 2 feet deep. In cold climates, dig below the frost line (typically 3-4 feet).
What type of wood is best for fences?
Cedar and redwood are naturally rot-resistant. Pressure-treated pine is more affordable and works well. All will last 15-20+ years with proper maintenance.
