The primary focus of our study is the characteristic distribution function of linear sizes [size distribution function (SDF)] of the GCs. We measure the effective radii for 652 clusters with point spread function-convolved King and Wilson dynamical model fits. The SDF is remarkably similar to those measured for other large galaxies of all types, adding strong support to the view that it is a 'universal' feature of GC systems. We use the Sombrero and Milky Way data and the formation models of Baumgardt & Kroupa (2007MNRAS.380.1589B) to develop a more general interpretation of the SDF for GCs. Description: Preprocessing of the raw image data is described in Paper I (Spitler et al., 2006AJ....132.1593S). The mosaics of six pointings in each filter were constructed at Space Telescope Science Institute and are publicly available. File Summary:
