what size are regulator gauges?

Are they, for the most part, all the same size?

If so, anyone know what size they are? 2"?

Looks like 2" is the common size.

as far as the thread, 1/4" npt (pipe thread). welding regs are 1/8" npt.

so, if I have 1 5/8" gauges now and I happened to knock my tank over and bend the fuck out of my tank pressure gauge, could I upsize to 2" gauges and benefit from a bit of additional size?

I'll do some measuring to make sure 2 2" gauges will fit, but if they do, am I good to go?

keep in mind the range of indication before purchase. i had some 0-100 corny brand gauges that had lousy resolutions... 10, 20, 30 was great but my coveted 12 psi, well not so easy.
