Of course, you can always measure the real nozzle diameter, indeed, but the thing impacting your printing is the extruded filament.
So, in a practical way, this diameter matters.
You can use mini drill bits, too.
BTW, it is interesting to enter the measured "spaghetti" diameter in the slicer filament settings, as we do for the filament diameter (entering 1.72 measured, instead of 1.75 by example). Indeed, the slicer is interested in the real volumes of plastic (input & output diameters) to compute filament advancement more accurately..
Now, if you focus on nozzle geometry, you can always make your own nozzle, like I do.
I wished to have more nozzle choice: 0.317mm 0.30mm, 0.28mm, between 0.35/0.25
This way, you have a total control on nozzle design.
