Question Phillips Head Screw Drivers

It is my understanding that there are four different head sizes for Phillips head screws and drivers.
X-Small 0
Small 1
Medium 2
Large 3
X-Large 4
How does one determine the proper size driver to use with a screw? I have not notice any coding on the boxes of screws of on the driver. Is it just by trial and error.

I am also curious about Phillips head screws.
In Canada the Robertson or socket is the standard screw. The sizes are well marked on the drivers and screw boxes.
Although I have some Phillips drivers with sizes on them, there doesn't seem to be any consistency as to which driver fits which guage of screw.
If I have a Phillips screw that looks like it will be a challenge I will place the closest fitting driver in the screw and whack it with a hammer to both help free the screw and help the driver tip conform the screws shape.
Am I alone in this?

I occasionally build outdoor furniture and do other woodworking.
I'm done with phillips all together. I buy #2 square drive screws for all my projects.

Yes there are different sized Phillips screws. The Craftsman tool catalog describes them pretty well.

I just use the one that's the best fit and gauge if it's tight or not .
