It says max door size is 12x14. So would it be the same if my door is 14x12?

Doesn't LiftMaster have a "contact us" page on their web site? Ask them.
I installed one in the race shop and really love it. Everyone who sees it, watches it work, and tries to listen to it is really impressed. Good money spent.

It shouldn't matter provided the roll up rolls down easily.

I wanted to know if anyone had real world experience with them and my size door.

I put one on a 12h x 16w sectional door, and really like mine as well. With yours (OP) being 14h, I'm not sure if the opener can handle the extra 2' of height but I would think so.
I was concerned with my door being larger (square foot wise) than Liftmaster stated, but mine works great. One other thing you need to be aware of is that the opener relies on some weight of the door to start itself on the downward path when it is rolled all the way up. If it won't start coming down on its own, you can add "pusher springs" to the rails to "assist" the door on its downward travel.
Pusher Springs
(best photo I have of the door, the Mercedes is long gone...)
