We are going thru a similar process.. from all of my reading, best practice discussions etc..

Here is what i have understood so far:-

Residential Customers:   /64

Small & Medium size Business Customers: /56

Large Business size or a multi-location Business Customer: /48

Don't skimp on allocating the subnets like we do on IPv4
Better to be 'wasteful' than have to come back to re-number or re-allocate .

Subject: IPv6 Default Allocation - What size allocation are you giving out

I am planning out our IPv6 deployment right now and I am trying to figure out
our default allocation for customer LAN blocks. So what is everyone giving
for a default LAN allocation for IPv6 Customers.  I guess the idea of
handing a customer /56 (256 /64s) or  a /48 (65,536 /64s) just makes me
cringe at the waste. Especially when you know 90% of customers will never
have more than 2 or 3 subnets. As I see it the customer can always ask for
more IPv6 Space.

/64
/60
/56
/48

Small Customer?
Medium Customer?
Large Customer?

Thanks

Erik
