Fence Calculator

Divide your total fence length by post spacing (typically 8 feet), then add 1 for the end post. Add extra posts for corners (1-2 each) and gates (2 per gate). For example: 100 feet with 8 ft spacing = 13 posts + corners + gate posts.

Standard post spacing is 6-8 feet for most fence types. Use 6 feet for high winds, heavy panels, or privacy fences. Use 8 feet for lighter materials in calm areas. Never exceed 10 feet between posts.

Typically 2-3 bags of 50 lb concrete per post for 4x4 posts in standard soil. Large posts (6x6) or soft soil may need 3-4 bags. Each bag fills about 0.4 cubic feet - a standard post hole needs about 0.8-1.0 cubic feet.

Bury posts 1/3 of their total length: 24 inches deep for a 6-foot fence (8-foot posts), 32 inches for an 8-foot fence (12-foot posts). In frost-prone areas, dig below the frost line - typically 36-42 inches.

DIY fence costs range from $5-15 per linear foot for materials depending on material type. Professional installation adds $15-30 per linear foot for labor. A typical 150-foot wood privacy fence costs $2,000-4,000 DIY or $5,000-9,000 installed.

Yes, double posts at corners provide better stability and easier panel attachment. Each panel can attach to its own post rather than sharing. This is especially important for privacy fences and areas with high winds.

Standard fences use 4x4 posts. Use 6x6 posts for: gates (especially wide ones), corner/end posts on tall fences, heavy panels like composite, or windy locations. Aluminum fences use smaller proprietary posts.

Most areas require permits for fences over 6 feet tall. Many require permits for any fence in front yards or near property lines. Always check local building codes and HOA rules. Call 811 before digging to locate utilities.
