It isn't a MH doll. First off, the logo is wrong. Secondly, as you said, the doll is much too big, and it's normal for fake MH dolls to have the real pictures on the box.

To check if it's Mattel made,  check the bottom for the Mattel symbol. If there is no symbol ANYWHERE on the box, you've got yourself a knockoff doll.
