Overview

Fence material estimation helps you budget for posts, rails, and pickets. For a typical wood fence, posts are spaced 6 to 8 feet apart, and pickets are calculated based on their width plus the desired gap between them. This tool ensures you order exactly what you need without over-buying.

Pro Tips

If your fence has many corners or gates, you will need more posts than a simple straight line calculation suggests.
Use pressure-treated lumber for posts and any parts in direct contact with the ground to prevent rot.
Check with your local utility company to have underground lines marked ('Call Before You Dig') before installing posts.

Fun Facts

"The Great Wall of China is the longest fence-like structure in the world, stretching over 13,000 miles."
"The Dingo Fence in Australia is one of the longest true fences in the world, built to keep dingoes out of fertile land."
"A standard privacy fence is typically 6 feet (1.8m) high, which uses three horizontal rails for stability."

Formula: Posts = (Length / Post Spacing) + 1; Pickets = Length / (Picket Width + Spacing)
