I need to build a door frame for a 686mm door. The reason I’m doing it is because I want a transom window and I’ve made the wall thicker by adding tile backer boards.
I’ve measured the door and it’s actually 684mm wide instead of 686, the door is new.
Is 686mm the width of the frame or some kind of nominal measure? What should be the internal width of a frame? I want to be able to change the door in the future without trimming it
