Fence Calculator for a Dog Run
Estimate posts and panels for a fenced dog run.
A dog run needs a fence tall enough that your dog can't jump it (5 ft for medium dogs, 6 ft for larger breeds) and dig-proof at the bottom — either an L-footer of hardware cloth buried 12 in horizontally or a concrete curb. Chain-link, welded-wire panels and vinyl-coated wire are the three most common materials.

How does the fence calculator work?
Posts = fence length ÷ spacing + 1 (for the end post). Panels = length ÷ spacing. Rails = panels × rails-per-section (2 for short fences, 3 for tall or heavy panels). Plan on ~2 bags of 60 lb concrete per post.
What else do people ask about this calculator?
How tall for a dog fence?
5 ft for most breeds. Add 12 in for large jumpers (labs, huskies, shepherds) and consider a coyote roller at the top if predators are a concern.
How many posts for a 20×20 dog run?
80 ft of fence at 8 ft spacing: 11 posts (10 + 1). Add gate posts.
How many fence posts do I need for 100 feet?
At 8 ft spacing you need 13 posts (12 sections + 1 end post). At 6 ft spacing, 17 posts.
How much concrete per fence post?
About 1.5–2 bags of 60 lb pre-mix per post for a 4×4 post in a 10 in wide, 24 in deep hole.
