Nozzle size comparisons

Does anyone have a good resource that compares outputs of different nozzle sizes? For example, how much finer detail could you get if you switched from a .4 to a .2? I know it’s not necessarily that simple but I’m just wondering if there is a visual reference of why you might want to switch to nozzles of different sizes?

I really should google before I post LOL
