How the fence calculator works
We divide your fence length by the post spacing to get the number of sections (and one more post than sections), multiply sections by the rails per section, and divide the total length by picket width for a solid privacy fence. Plan on about two bags of concrete per post.
Frequently asked questions
How far apart should fence posts be?
6 to 8 feet on center is standard for wood fences — 8 ft is most common, with closer spacing on windy or uneven ground.
How much concrete per fence post?
About one to two 50 lb bags of fast-setting concrete per post, depending on post size and hole depth.
