I can sing quite low and I can sing comfortably until about G3 which is kind of high to sing :/
It's more about the weight of your voice than the range. I can squeak out some pretty high notes, but that doesn't make me a soprano!
Where are you happiest? Where do you sound best? Are you more likely to pick "Nessun Dorma" or "Old Man River" as a party piece (not necessarily in the original keys)?
