Typically a /48 is suppose to be the smallest block advertised out as ARIN and I believe all other registrars recommend a /48 per site. However looking at my tables I am seeing /64's from multiple upstream AS'. 
Im sure it will eventually fall on a /48 with certain providers filtering anything other then a /32 or less out.
