Fence Post Spacing Calculator

To calculate fence posts, divide your fence length by the desired post spacing and add 1. For example, a 100-foot fence with 8-foot spacing needs 13 posts (100÷8=12.5, rounded up to 13, plus 1 = 13 posts total). Don't forget to add corner posts, gate posts, and end posts.

The optimal spacing between fence posts is typically 6-8 feet for most residential fences. For heavy-duty or high-wind areas, use 6-foot spacing. For lighter fences or cost savings, 8-foot spacing works well. Never exceed 10 feet spacing as it compromises fence stability.

Yes, corner posts and gate posts typically require larger, stronger posts than line posts. Corner posts handle tension from two directions, while gate posts support the weight and stress of opening/closing gates. These should be larger diameter and set deeper than regular line posts.

Fence posts should be buried at least 1/3 of their total length, with a minimum of 2 feet deep. For a 6-foot fence, use 8-foot posts buried 2 feet deep. In areas with frost, posts should be buried below the frost line to prevent heaving.

Key factors include fence height, wind load, soil conditions, fence material weight, and local building codes. Taller fences need closer spacing, while sandy or loose soils require more frequent posts. Always check local codes for minimum requirements.

For a 200-foot fence with 8-foot post spacing, you need 26 line posts (200÷8=25 spaces + 1 post = 26). Add corner posts (typically 4 for a rectangular area), gate posts (2 per gate), and any end posts for the final count.

Yes, but within limits. Increasing spacing from 6 to 8 feet can save about 25% on posts, but don't exceed 10 feet for most applications. Consider your fence material, height, and wind exposure. Sometimes closer spacing prevents costly fence failures.

Line posts are the regular posts along straight fence runs, while corner posts are larger, stronger posts placed at fence corners and direction changes. Corner posts typically use 6x6 inch or larger lumber versus 4x4 inch for line posts, and are often set in concrete.
