if you have a small face, you will use a small gas mask. If you consider yourself to have a large face, you will be a size large.
it's really easy to guesstimate mask size.
Also, having used a gas mask for CQB for quite a while (I also jog on the treadmill with it to train my lungs), DON'T GET THE P.O.S. ISRAELI CRAPMASK
1) Go american or go home, they have the best masks by far
2) The M42 is readily available on ebay, I think it's now obsolete as well so there should be lots
3) Always always always upgrade them to polycarbonate lenses. Just assume no gas mask is even remotely close to be ballistic rated (If you're wearing a mask and get hit by shrapnel, losing an eye or two is the LEAST of your concerns)
You can get polycarbonate sheets from mcmaster carr, to form them, cut them to shape of the old lenses, make a curved die (like from old sheet metal or something), lay the lens on it and heat your oven to 350, as soon as the polycarbonate starts to sag take it out. It'll conform to the mold and set within about 15 seconds.
