does jam jar size matter?

I'm planning on canning some jam as fruits come into season this year. We eat loads of jam.

All of the jam canning recipes always call for 8 oz jelly jars. Is it OK to use bigger jars - say 16 oz pint jars?

The canning recipes always warn not to changing anything for food safety reasons. I'm wondering if the time in the steam bath has to change depending on jar size?

thanks!
