What is the size of the interior doors? 90 or 100 cm / 211 cm?

Exaggeration usually looks less.

Is that really already exaggerated (223.5 high door with 263 high ceiling), what do the experts say?

The answers have already flowed - not from the expert, but from the consumer. If you want answers from the expert, then ask your carpenter.

I am also very grateful for the answers. However, I would still appreciate opinions from those who know the comparison from various personal experiences. For example, planners, professionals, etc. represented here.

Flat people follow DIN and not opinions. By the way, the former does not exist here.

Now it's getting absurd.

Experts with corresponding experience will very well be able to say from their own feeling whether they believe it could look good.

Therefore, once again the question to professionals with corresponding experience:

Do you also think that 223.5 doors are too big for rooms 263 high and no longer look good?

Hello

That looks perfect.
If the rooms/the house allow it, gladly also 1m wide
