How do you know what size hole to drill for a pop rivit?

I would suggest finding the manufacturer's sizing charts like this one. I don't think you would need too much clearance between the hole and the rivet, so you should probably use the closest larger bit size.

If you hold the bit in front of the shank of the rivet, you should be able to get a pretty good idea if it will fit.
