Fence Gate Calculator
Calculate gate dimensions, post requirements, hinge placement, and hardware for single and double fence gates.
How It Works
Gate dimensions should be slightly smaller than the opening to allow for swing clearance (typically 1/2" on each side). Gate posts must be stronger than line posts — use 6x6 for wood gates or heavier terminal posts for chain link. Double gates need a center drop rod to secure the inactive leaf. Pool gates require self-closing hinges and self-latching hardware per code.
Frequently Asked Questions
How wide should a fence gate be?
Walk gates: 36-48 inches (3-4 ft). Equipment access: 5-6 ft. Vehicle/drive gates: 10-12 ft (double gate). Always make gates slightly narrower than the opening — leave 1/2" clearance on each side for swing.
Do I need special posts for a gate?
Yes. Gate posts bear the weight of the gate and repeated opening/closing stress. For wood, use 6x6 posts (vs 4x4 for line posts). Set gate posts 6" deeper in concrete for extra stability. For heavy gates, consider steel-reinforced posts.
What hardware do I need for a fence gate?
Minimum: 2-3 hinges (depending on gate weight), a latch, and a gate stop. For pool gates, add self-closing hinges and a self-latching lock that meets local code. Heavy gates may need a wheel support.
