what size connectors

is there a way to learn what size connector is the right for a certain motor?
for instance, park 300 motors come with 2mm golden bullets.
like the watts-amps of a motor to diameter of the connectors or what?
i don't want to use something that is too small and can't take the load,but neither overdo it.
or there are charts or formulas? link?
thanks

Electrically, it's probably not too critical. A 2, 3 or 4-mm bullet will probably cover most of the needs encountered by modelers. Even a 2-mm bullet can handle many amperes of current. Mechanically, it is probably more important (or necessary) to choose a bullet size that is compatible with the wire gauge used on the motor. This will ensure a good fit in the bullet connector and a strong soldered connection in addition to somewhat better current-carrying capacity.

thank you very much. i had the feeling that 2mm bullets can handle a lot, but needed some expert's confirmation. i have standardized my stuff to 2mm from the beginning and am trying to stay with that. as you say, as long as the wiring used fits.
regards

Here is a google translation of a German page that has a very useful comparison on a lot of the common connectors used in RC:
