We discuss different criteria for the {open_quotes}classical size{close_quotes} of extremal Dirichlet p-branes in type-II supergravity. Using strong-weak coupling duality, we find that the size of the strong-coupling region at the core of the (p{lt}3)-branes is always given by the asymptotic string scale, if measured in the weakly coupled dual string metric. We also point out how the eleven-dimensional Planck scale arises in the classical 0-brane solution, and also the ten-dimensional Planck scale in the D-instanton solution. {copyright} {ital 1997} {ital The American Physical Society}
