Hand span

[cabbynum]

I've recently started teaching, I've got a group of 10 students, ranging from 6 -15. 3 of them really seem to enjoy it. The rest are obviously forced by their parents. One little girl that I teach who really enjoys it is 8 years old. She is movig along very quickly in the lesson books and is very excited each lesson! That makes me happy. But, the thing that is amazing is the size of her hands. 8 year old girl, barely as tall as my chest and I'm about 6'. She can reach a 9th with a little bit of stretching and an octave with ease. Her mom who is not a tall woman can reach an 11th easily.
I'm 6ft I can reach a 10th with a little aggravation and an 11th if I try really hard and on a good day.

out of curiosity what can you all reach? What about in between individual fingers?
What are your thoughts on having big hands vs. small hands.
