The level of coolant should be maintained at the “FULL COLD” level or within the “COLD FILL RANGE” in the coolant reservoir.

The reservoir usually has fill line marks. If all else fails, read your owners manual.
Having the coolant system pressure tested is the easiest and best way to find leaks. GL

Mine is at the "Hot" mark when hot, and half way between hot and cold when cold. You should not have any puddles under the car.

Does you coolant level fall over time. Mine constantly fall but there are no leaks under my car... have no idea where the coolant is going...

No, the coolant level should not be dropping, even over time. At least not at the rate that you would notice over few days. Yes, the coolant evaporates slightly over time, but that loss is not significant, and maybe every few months you may need to add some.
When I was loosing coolant, it was from a cracked radiator and I saw it under the car, and then when a heater hose Y junction cracked, I was loosing it very slowly but noticeably, but I did not see anything under the car. I thought my head gasket was out, but then I found it on the right hand side of the engine compartment the line going to the rear heat was leaking.
