What Materials Do I Need for a Fence Gate?
Every gate needs two sturdy posts (one for the hinges, one for the latch), a rigid frame with a diagonal brace, two or three heavy-duty hinges, and a latch. Gate posts take far more stress than line posts, so most builders use 6×6 posts or set 4×4 gate posts deeper with extra concrete.

Detailed Answer
Single walk gate (3–4 ft wide): - 2 gate posts (6×6 recommended, or 4×4 set deeper) - 4–6 bags of 60 lb concrete - 2×4 frame: top, bottom, and one diagonal brace running from the bottom hinge side to the top latch side - Pickets to match the fence - 2 heavy-duty hinges (3 for gates taller than 5 ft) - 1 gravity latch or self-closing latch - Optional anti-sag cable kit
Double drive gate (10–12 ft opening): 2 gate posts (6×6), two gate leaves, 2–3 hinges per leaf, a cane bolt (drop rod) to hold one leaf closed, and a center latch.
Typical cost: wood walk gate kits run about $75–$200, vinyl about $150–$350, and wood double drive gates about $200–$500. Add $30–$60 for hinges and a latch.
