Fence Calculator

Plan out a fence build without making three trips to the lumberyard. Enter total length, fence type, post spacing, and number of gates — we'll tell you how many posts, panels, rails, and concrete bags you need, plus a quick cost estimate.

Standard wood privacy fence uses 8-foot panels with 3 horizontal rails. For chain link, the post spacing can stretch to 10 feet between terminal posts. Always set corner and gate posts deeper (3 ft) than line posts (2 ft) and bag the concrete dry — moisture from the ground cures it over a few days.

Tips for Estimating Fence Materials

Most fence calculators undercount posts. Remember: a 150 ft fence with 8 ft spacing isn't 150 ÷ 8 = 19 posts — it's 19 + 1 = 20, because you need a post at both ends. Same logic applies to every corner and gate post. Always order 10% extra panels and 1–2 extra posts as backup; they're cheap insurance against a warped board or a botched concrete pour.

If your run isn't a clean multiple of the panel size, the last panel will need to be cut. Buy a full-length panel for that section anyway — partial panels are rarely sold and cuts are easier than splices.
