Fence Calculator

Standard fence post spacing is typically 6 to 8 feet apart, measured from center to center. Here are some guidelines:

• Wood privacy fences: 6-8 feet spacing works well
• Picket fences: 6-8 feet is standard
• Chain link fences: 8-10 feet spacing is common
• High wind areas: Consider 6 feet or less for more stability

Closer spacing provides more strength but requires more materials and labor.

The general rule is to bury one-third of the total post length underground. For example:

• 6-foot fence: Use 8-foot posts, bury 2 feet deep
• 4-foot fence: Use 6-foot posts, bury 2 feet deep
• 8-foot fence: Use 12-foot posts, bury 3-4 feet deep

In areas with frost, posts should be set below the frost line (typically 30-48 inches) to prevent heaving. Always check local building codes for specific requirements.

For maximum privacy, consider these height recommendations:

• 6 feet: Most common privacy fence height, blocks views from standing neighbors
• 8 feet: Maximum privacy, may require permits in many areas
• 4-5 feet: Provides some privacy while maintaining openness
• Front yard fences: Often limited to 3-4 feet by local codes

Always check your local zoning laws and HOA regulations before building, as many areas have height restrictions.

Permit requirements vary by location, but you typically need a permit when:

• The fence exceeds a certain height (often 6 feet in backyards, 4 feet in front yards)
• You live in a historic district or have an HOA
• The fence is near property lines, sidewalks, or public right-of-ways
• You're installing an electric fence or security fence

Before building, contact your local building department, check for underground utilities by calling 811, and verify property boundaries with a survey if needed.
