The USB-C specification[0] recommends a minimum 12.85mm heart-to-heart distance between ports. Fine for cables, probably not fine for dongles.

USB-A mandates[0] a maximum overmold size of the plug of 16mm, so the minimum heart-to-heart distance is going to be a hair above that, although I don't think anyone is placing them that tightly together in practice.
