Shoulder Bell size?

Anyone have a rough dimension on the correct measurement for shoulder bells? Maybe their widest and longest point? I have a pair, but they look big to me. I've never actually seen a pair in person, so maybe they're perfect. Mine are 6.5" top to bottom x 6" at their widest point through the middle. That sound about right?

Thanks!

Take a look at the Wizard of Flight templates available here. That should give you a good idea of scale. That doesn't sound too huge, but I've never really measured mine.

I also used the WOF templates for my shoulders and they look fine to me.
