Calculate posts, rails, and materials for fence installation
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.
