As I understand from the answer to this questions, plug doors are larger than the hole they mus fit in so that they are plugged thanks to air pressure, leading to several advantages. Then, I found this video of a type-C door operating. This door does not seems larger then the hole it must fit in and that confuses me.

  • Is this a plug-door?
  • Is there something I miss?
  • Is there other types of door that are not plug-door, or that are plug-door but don't look like plug-door?

No, they are not. Most (not sure if all) Airbus door are not plug-type. And neither are cargo door on most Boeing types.
