Designing a barb wire cow fence

A barbed wire fence can help very much in keeping your animals in a specific place. You need to establish the right height of the fence, so that it will be effective and to not use too much material. Installing a barbed wire fence depends very much on the material you use, whether it’s wood or metal.


  1. First, you should make some measurements to determine how much barbed wire you will have to use. Posts should be placed at 10 feet apart. If you like more for your corner posts, there is no problem in using live trees as posts. Try not to choose a specie that will live short or grow too much, because this will cause only problems for you.
  2. You need to choose your favorite material for the fence. You may choose either wood or metal, or if you want you can use wooden posts on the corners and metal for the rest of the posts. Compare costs to decide better.
  3. Although posts should be placed 10 feet apart, 6 to 8 posts are better for your cattle’s safety. Some important specifications for the corner posts is that they should have 5 inches in diameter and they need to lean 2 inches in the opposite direction of the pulling.
  4. The necessary barbed wire has to also be decided. The number of stands should be three and they need to be positioned at the top, bottom and the middle. Take into account that you may need a foot of wire only for one post because it needs to be wrapped around the post. It’s better to buy more than you have established because you may need it for repairing.
  5. Corner posts need a corner-brace design that will lean diagonally into the ground. The braces should be positioned either at 8 inches from the top of the post or at least 3 feet above the ground. The length of the brace should be about 6 feet and it should be sunk into the ground at a depth of one foot.
  6. Think about the fence gates. The size of the gate should give you the possibility to drive the cattle through comfortably and to have enough space for farm equipment. Even end posts should be braced just like the corner posts.
  7. Is better to take into consideration sectioning your pasture for rotational grazing. Depending on the herd size, you will determine the size of the pasture section. After the grass is almost trimmed to the ground, the cattle should be taken to one of the other sections. This way the grass will recover more quickly.


  • The new barbed wire can even be electrified, but this will mean a fence charger, insulators and time and energy for setting up and maintenance. The only reason for which you should install an electrified barbed wire is if your cattle would rub against the wire, breaking the posts.
  • Try to treat all the metal you use for fasteners and braces.
