How's this for an ambiguous answer....yes, to some degree, but not always.
Some minute land snails (and marine, I'm sure) have proportionately (the
operative word) large radulae and some large snails have proportionately
small radulae, take the cones for instance.  It depends more on just what
the critters are doing with it.

Interesting. Does a snail's radula grow throughout a snail's life?
Within a genus, are the radulae of large species larger than the radulae of small species?
