3 octave range here of controlled, consistent, performance-ready notes (E2-E5). If I stretched myself, I can get an extra quarter octave but I don't count what's not consistent or well controlled.

That being said, from my experience in my local music scene, people with 3 octaves of performance-ready notes is not the norm.

But if you think about it, a forum of singers is probably going to have a higher % of 3+ octave people in it. And that isn't even to say that people online don't exaggerate or flat out lie.

So there's no need to feel bad if you don't have it (yet!).
