My door frame measures 3 cm in height and is 2 cm deep (up to the wall), which fits. In my opinion, frames that are too high are not possible with this product. But the depth is important, the 2 cm barely fit my frame.

the door frame should be a maximum of 5cm high to allow the door frame to be hung securely.

my frame is 4 cm in height and 1.5 in depth. i felt it worked okay
