A general correction term in the radius of gyration scaling law is discussed. The work incorporates the finite size effect considered by Ball and Jullien (J. Phys. Lett. France 45 (1984) L1031) and is a potentially useful extension of their analysis to polydisperse systems. Numerical simulations verify these results for one particular model, and demonstrate the remarkable accuracy of the scaling law, even for clusters of very few monomers, once this relatively trivial scaling correction has been made.
