So I was wondering, how big are your hands? I know some people use regular units, but being musicians, we usually measure using intervals on a piano. Also, if you think age might be a factor, go ahead and say that too. I'll go first: I can stretch a P11 on a keyboard, but it's only practical for me to stretch for a Maj. 10th. Edit: I'm 16, so my hands might not be at full size yet.
