Let's see if you are doing public construction or residential use first. Generally, companies looking for doors have many complete sets of things.

I don't know what you are talking about. The size of the door or the thickness of the door panel! The door opening is the same as the wall thickness. It is common to have a 5- 15 outer bread door frame on both sides, and the special decoration requirements are thicker. Door panels are generally 20, 25, 30 ... There should be many sizes, which are related to the materials you choose. The simplest, a layer of glass, may be less than 10 thick, of course, the door frame and grille are counted separately.
