The minimum (and maximum) subnet mask for a LAN in which -all- of IPv6's technologies work right is /64. If you don't require stateless autoconfiguration or automatic link-local addresses, you can pick any subnet mask you want. In most cases it's desirable to have a size of /64. In a few cases it's not. Short version: use /64 as your IPv6 LAN subnet mask unless you clearly understand the consequences of not doing so and intentionally want them.
