# What gauge fence post should I use for a 36" wide wooden gate?

I want to attach a gate to a fence where the fence will be attached to a 2 3/8 in. metal post. What gauge should the post be for proper support?

The fence will be a six foot wooden fence, as will the gate. The gate will be no more than 36 in. wide.

I don't have the exact math for you, but if it's a metal fence post, I'm sure it's sturdy enough to handle a gate. More important would be what the post is supported with, IMHO (depth in ground, material surrounding the post, etc.) – DA01 Apr 20 '11 at 14:56
@DA01 - I'll be using an 8 ft. post set into the ground 2 ft. with some quikrete for good measure. My confusion is that I'm seeing several kinds of posts; "regular" - 16 gauge and "corner" - both 15 and 13 gauge. – uncle brad Apr 20 '11 at 15:35
Is there a huge price difference? If not, pay a bit more for the heavier post. FYI, from what I know/heard, you want 1/3 of the post in the ground. So, a 6' fence should have 3' in the ground. That said, 9' posts are probably not that common, so you might be find with 2'. I'd have to defer to the experts... – DA01 Apr 20 '11 at 15:37
@DA01 - Yeah, it probably can't hurt to go with the heavier post for \$4.00 – uncle brad Apr 20 '11 at 15:40
Is the post square or round? I could do some simple bending moment calculations for you if you'd like. Just give me the possible cross sections and mounting heights for the hinges, as well as an estimate of the gate's weight. Or you could sketch up the gate and specify what dimensional lumber you're planning on using. Finding the centroid and mass shouldn't be hard given the geometry. – Doresoom Apr 20 '11 at 17:31
