You could take the spindle off, trace a circle around the outer diameter and measure it with a ruler. Most stock cranks and cheaper aftermarket cranks are 19mm. Is your bike a custom or a complete?

It's really not important what's in there now, now would be a great time to install a new bottom bracket. Buy a new bb in the correct size for the new crank set up.

What cranks? Post a pic of the axle

It's probably going to be a 19mm or a 22mm but my money is on 19mm. But, yeah, a pic would help..... preferably something along side a common item for comparison (i.e. a quarter, a seat post, etc....)

Take a pic of the bottom bracket... I personally can usually tell what size by looking at the bottom bracket.

I don't crash, I do random gravity checks...

A new spindle will come with a new set of cranks. It should tell you what size it is. Just order a new bottom bracket at the same size and you know you'll be good to go.
