About This Fence Calculator

Our fence calculator helps you determine how many posts, rails, and pickets or panels you need for your fence installation. Whether you're building a privacy fence, picket fence, or ranch-style fence, this tool calculates materials based on your total linear footage and post spacing.

Accurate material estimation prevents mid-project trips to the store and helps you budget correctly. The calculator accounts for the number of posts needed (including end posts) and estimates rails based on standard three-rail construction. Picket counts are based on standard 3.5-inch pickets with spacing.

This tool is designed for DIY homeowners planning fence projects, contractors preparing estimates, and anyone asking "how many posts do I need for 100 feet of fence?" Remember to check local building codes and property lines before installing a fence.
