Look on the side of the nozzle(not the cap), there should be some numbers on them like 1.3, 1.4, maybe 1.5 or bigger as well.
The numbers are the size of the opening where the fluid flows through.
Bigger numbers are for thicker paint. Though at work I use a 1.3 to spray primer which most people would consider small for that task.
