What is the maximum length of a facebook name?
What is the maximum length of a facebook name, the one you get in the parameter "name" from the graph API.
Maximum length of a Facebook username is currently 50 characters.
While trying to create a "really long name" as @BK suggested, the Facebook user account view complains with anything of 51 characters or greater:
I'm pretty sure that its not documented anywhere, but my guess would be 50 as the longest one I've seen after looking over several hundred thousand users is 49.
I recently encountered a unicode name (first & last name combined) that exceeded 255 bytes, unfortunately I don't recall how many characters specifically, but it broke our varchar(255) database field.
