How Large Of A Pot Should I Use When Re-potting My Orchid?

I recently got an orchid as a gift. I'm waiting for it's second bloom and then I think I need to re-pot it.

The roots look root bound (it has a clear inner pot so I can see the roots) and there seems to be little media left in the pot. The roots seem to be as big as the pot is.

The pot is 5" dia. and 6.5" tall. What size pot should I move up to?
