Proper Fence Post Spacing
The proper fence post spacing ensures the fence remains upright, does not sag or lean, and can withstand external forces. Fence posts are mostly spaced 8 to 12 ft apart as a general rule; scenarios may vary. For instance, high tensile fence posts can be 15 to 20 feet apart for field fences, and 20-30 feet for high tensile barbed and smooth wire.
How Deep Should Fence Posts Be?
How Deep Should Fence Posts Be for effective fencing? Proper post depth provides long-term stability. Dig holes 1/3 to 1/2 the height of the post above ground, plus 6 inches for gravel. How to Secure Fence Posts for sturdy, lasting fences? Fixing posts properly ensures a sturdy, long-lasting fence. Follow step-by-step instructions on securing fence posts.
Fence Post Spacing According to Style
Post spacing depends on the fence style. Fences with 8-12 foot post spacing include field fences, picket fences, split rail fences. Farther spacing is possible for high tensile fences. Wire fences need less support but enough posts to maintain tension. Fence purpose also affects spacing.
Chain link fences can have ten foot spacing, but top rails may sag without added support from line posts. Install slats or live in heavy snow? Go with six foot spacing. Standard barbed wire or woven wire fence post spacing is 10 to 12 feet but varies with terrain. More posts on slopes. Climate, soil conditions, wind loads also factor in. Light soil means closer spacing than heavy soil.
Follow the one-third to one-half above ground height rule for hole depth. Slope concrete away from posts to avoid rot and water pooling. For example, a six foot fence needs posts buried two to three feet.
T-post spacing is six to eight feet for fencing with wire mesh. Use wood posts at corners and gates to handle tension. High tensile field fences can safely have T-posts 15 to 20 feet apart. Up to 30 feet for smooth wire and barbed wire high tensile fences.
How Far Apart Should Fence Posts Be?
How far apart should 4 ft fence posts be? Fence posts should be spaced 6 to 8 feet apart on a 4-foot fence. Anchor posts should be every 30-50 feet with T-posts every 10 feet for woven wire fences.
Longevity of Treated 4×4 Posts
A treated 4×4 post can last 20 to 25 years in favorable soil and climate conditions. With concrete, it may last 40 to 75 years.
Other Considerations
Dig post holes 1/3-1/2 the height of the post above ground, plus 6 inches for gravel. A 6-foot fence needs a 2 feet deep hole. Spacing for 4×4 deck posts should be 6 feet with 8 feet for 6×6 posts. Experts say to dig 2 foot deep holes for timber posts. Proper post spacing keeps fences upright and sturdy.
