I will throw my two cents in, but reiterate - what Berta said - tool height matters and I will add tool material and geometry matter. Finally what you are turning matters!
Large bowls? pens? spindle work? vessels?
Think of the carbide tools that like to be parallell to the centerline of the lathe - it can be uncomfortable if the lathe is too high... too low likely doesn't matter until you drop below the elbow, then you are reaching down or your arm and body posture is uncomfortable... exactly as
@bob vaughan points out...
At home, I use traditional tools and a HIGH rake angle so my lathe is slightly higher so my left hand is presented slightly above centerline and I can reach "Down" to the tool with my forearm parallell to the work. While my right hand is likely at 3/4 or at the end of a LONGER handle at or below my hip.
(ask anyone who has seen me struggle with the carbide tools and the lathes on the outreach trailer - I am simply not used to that kind of turning...)
So with all that said, as everyone else has pointed out - if you are comfortable - the height is likely right, if you are uncomfortable, pay attention to your body and what "hurts" or get stiff and it can give you a signal as to what you need to adjust.
I hope that helps and is not too much of a reiteration of the 10 people who have come before?!
