The standard size assignment to an end user is /48 per IETF recommendation. That's 65,000 LANs, 2^80 IP addresses. Vanishingly few end-user organizations actually have a need for more LANs than that. However, since /48 is also the minimum Internet routable size, end-user organizations with multiple independently-connected sites may need several /48s. That's a minority of end-users but still a significant number. ISPs get a /32 so that, by default, they can assign 65,000 /48s to their customers and still keep a few for themselves. That's the reason they receive significantly more.
