How to Build and Hang a Sturdy Fence Gate

GATES are the most overworked part of any fence, taking constant hits from wind, gravity, and daily use. A well-built gate relies on the architecture of a triangle to keep its shape over years of service. If you build a square frame without a structural brace, your gate will eventually drag on the ground regardless of how expensive your hardware is. Success here comes down to precision in your measurements and patience while setting your posts. A gate is only as stable as the post it hangs from; if that post shifts even an inch, the latch won't line up. When you build with the right dimensions and ensure your hinges are anchored into solid wood, you create an entry point that feels solid and swings smoothly for a decade.

  1. Measure Before You Cut. Measure the opening at the top, middle, and bottom to find the narrowest width, then subtract one inch to account for hinge and latch clearance. Cut your frame boards to these dimensions and lay them out on a flat surface to ensure they form a perfect rectangle.
  2. Square Every Corner First. Join your vertical and horizontal frame members using exterior-grade wood screws. Apply a bead of waterproof wood glue to each joint before screwing them together for added structural integrity.
  3. Add the Sagging Prevention. Place a diagonal board running from the bottom hinge-side corner to the top latch-side corner. This brace carries the weight of the gate to the hinge post, preventing the gate from sagging over time.
  4. Space Pickets Like a Pro. Lay the frame on your work surface and attach the fence pickets one by one, ensuring they overhang the frame edges evenly. Use two screws at every point where a picket meets a horizontal frame member.
  5. Mount Hinges with Shims. Position the gate in the opening using shims to hold it at the correct height. Attach your hinges to the gate frame first, then secure the other side of the hinges to the heavy-duty latch post.
  6. Test Before You Commit. Once the gate swings freely, align your latch mechanism on the opposite side. Test the engagement multiple times before driving all screws to ensure a smooth, secure lock.
