    Person._meta.get_field('name').max_length will give you this value. But having to use _meta suggests this is something you shouldn’t do in normal usage.

    Edit: as Carl pointed out, this naming is misleading and it does seem quite acceptable to use it: http://www.b-list.org/weblog/2007/nov/04/working-models/
