How to Avoid Type Casting?

Hi,
      I feel as if I'm always type-casted in shorter roles... It's understandable in shows where other actors are over 18, but in high school productions it's like I don't have a shot at larger roles because of my height. My singing voice isn't one you'd expect a kid to have, since I'm a coloratura soprano on the classical/opera side (although I use this little kid singing voice after being casted).

Any tips to avoid this?


Please help.

Thanks!

I didn't find the right solution from the Internet.
