I'm not going to tell what you size you should give your customers, you should determine that for yourself.  But others on this thread have suggested /48, /56, and /60, those all seem reasonable to me depending on the situation.  What I will beg you, do not limit your customers to a single /64 subnet in there homes.  There are many valid reason to have more than one subnet in a home, easiest example is a separate Guest WiFi subnet.

See the following for way more details;

Hope that helps.
