Pumice size for succulent, potting and perennial containers

I have been adding pumice to my succulent mix and also want to try it with a general potting mix and outdoor perennial containers.

I used to buy a "medium" sized pumice, but now can only get fine or coarse. Are either of these OK? The coin is a 10 cent piece.
