Materials for 100 feet of fence
All figures assume one 4 ft gate, and 10 in post holes. They are for a straight run, so add a post for each corner.

Before you build
Check your property line, call 811 before digging, and look at local rules on fence height and permits. Use ground-contact treated posts, and set them about one third of the fence height deep. See the post spacing and depth guide.
