You re not going to be able to calculate a minimum gap very easily.
Gap between shower door and ceiling.
Place a strip of fiberglass mesh drywall tape over the gap so that it butts up against the ceiling line.
Having said that my shower has just over a foot between the top of the glass and the ceiling and that seems to allow plenty of convection.
The distance between the tray and the ceiling is 1 96m.
There s so many factors involved temperature of the room air humidity where you live fan throughput temperature and materials of walls and ceiling typical duration and frequency of shower water temperature room size.
I have about 2 foot from the top of the shower door to the ceiling i am thinking of building the 2 foot section.

Leaving about 5 inches between the shower door and shower assembly but want to make sure i have enough room to let the moisture to vent.
Sorry to hear about the issues you are having with your recent shower enclosure installation.
A transome and a well place fan will draw air out the top of a shower and allow air to enter around the door.
Shower doors should be installed in such a way that nothing interferes with their movement and there are no gaps between the door and the wall.
Cut the tape with a utility knife as needed to fit the gap.
The industry standard is 1 16 but i think even that is pushing it.
About 5 inches from the top of the shower door to the top of the shower assembly.
Shower enclosure seem to come in 1 85m 1 9m and 1 95m.
I have about 2 foot from the top of the shower door.
The less you have the more concentrated the steam at the top and the more damage the steam will cause.
So get as much space as possible while getting a shower door that you can get.
To the ceiling i am thinking of building the 2 foot section in and.
The one i like twyford t4 or geo6 is 1 9m.
