Fence Calculator
Calculate fence materials: run length and post spacing give post count, panels, rails, concrete bags and total cost.
About this tool
Fence calculators are the difference between one order and three trips to the hardware store. Enter the run length and spacing to get posts, panels, concrete bags and a materials cost.
Post spacing drives everything: closer spans cost more material but resist wind and last years longer on a property line.
FAQ
How far apart should fence posts be?
6-8 feet for wood panels, 8 feet for many vinyl and metal systems. Closer spacing means a stronger fence and more posts.
How much concrete per post?
One to two 50 lb bags per post, depending on hole depth (typically 2-3 feet) and soil.
Should I add a gate?
Gates need a rigid frame and a concrete-set post on both sides — add roughly 15-20% to the material list.
