Telling airbrush nozzle size

[merchant1307]

bought an airbrush two years ago i think the single action is either a .5 or .8 nozzle is there an easy way to tell if I have a set of calipers?

Try and find .5mm wire or .8mm wire otherwise you would need a pin gauge of those sizes. To small for calipers to get a good reading.

Why is the nozzle size that important?  There isn't all that much difference between 0.5 and 0.8 mm and since the needle is adjustable you should be able to get the paint flow you desire from either nozzle.

Good question.  Are you thinking about buying a new one with a different size nozzle?  Just FYI .5 is generally listed as "fine", .8 us a "medium" and 1mm or more is a "large".
