What's a Standard size..

I was wondering what the O.D. and I.D. of 2x3 box tubbing is, is there different sizes or does it come in a standard size..

i could be wrong but the od is goin to be 2x3 and the id depends on thickness...

I always thought O.D. & I.D. had to deal with circles like tubing, airline, etc.

The OD is going to be 2"x3" the ID on 1/4 wall tubing would be 1 1/2"x2 1/2"

Most of the material that we use is measured on the outside, because that is the dimension that matters most. (material that is measured on the inside is usually used for fluid transfer of some type- ie. water pipe.)

So a piecs of 2x3 would measure 2" by 3" on the outside. The inside dimension would depend on the wall thickness. The most common wall thickness for frames are .095 or 3/32 .120 or 1/8 .188 or 3/16 and .250 or 1/4To calculate the inside dimension you would subtract 2x the wall thickness from each length.

tubing width - 2 x wall thickness = inside width

example-2 - 2x .120 or 1/4 = 1.750 or 1 3/4

This really is something that many beginers are not aware of. I personally remember wondering the same thing.

Wut's up Max, I appreciate the info, now I can actually order the stuff and know what the other guy on the end of the phone line is asking...
