In general, large crabs are older than small crabs. The only way you can accurately estimate your crab's age is if it dies. Then the otoliths, small concretions of mineral deposits, which sit atop the crab's balance organ (located at the base of each antennule), need to be removed. The otoliths can be sectioned and the number of growth rings counted.
