I just built all of my benchwork for my 16x13 O gauge layout. I did it all with 2x3 studs in an open grid configuration with 2x3 supports every 15 inches and 1/2 inch plywood on top. It seems sturdy as can be but should I have used 2x4's? The last thing I want to do is tear this all out and start over.
 
Absolutely NOT. You could have gotten away with 1X3's. If my mental image of what you describe is correct, or very nearly so, you should be fine, and have almost overbuilt it.

I essentially built it like I was framing in a wall. I built a box out of 2x3's then I put in 2x3 studs every 15 inches topped off by a 1/2 inch peice of plywood screwed to the top.

I thought I would be ok then I started reading posts where people were saying to build it out of no less than 2x4's! I got a bit nervous.
 


Nah, you could have a dance party on that thing. :) 2x3 studs are only a little less beefy than 2x4's, and many modern 2x4's aren't much larger than 2x3's anyway. You should be just fine.

2x4 actually is 1 1/2x3 1/2.
Not sure if 2x3s are any smaller than their actual dimensions.
 
No, you didn't. MDX was quoting the nominal measurements of 2x3's, not 2x4's. As I said, if you can get some "real" 2x3's, they are only silghtly smaller than the so-called 2x4's we have today.
 


Heck yeah! Jump on in.

Jim, U.S.A. 1x and 2x (dimensional) lumber always has and is a size based on a standard. Where we run into problems is buying lumber (Lowes, Hodo) manufactured for export or imported lumber, all that have been cut to metric and roughly converted to our US units.
 
True, Rex, the whole metric thing has screwed up our idea of what the old 2x4 really measures. You can still buy a real 2x4 or 2x3 from a "real" lumberyard. If you buy it from a big box store, you get the export, metric equivalent lumber. I still like to know that a 2x4 I buy actually measures 2" by 4", even if it costs more.

Josh, no fighting in the war room. :) Wolfe apparently misread that MXD was posting the correct nominal size of a 2x3 in reponse to an uncertainty about the meaurements of a 2x3 that Wolfe himself posted.
