Old door demolished, passage to living room different width, what can be done?

[Micke1994]

As the title states, I realized after installing plasterboards and applying filler, etc., that the width of the passage into the living room was different, resembling a V 😮‍💨; at the bottom, it's 86.5 cm, and at the top, it's 90.5 cm. It just looks so bad; what can be done to make it even and nice? I was a bit quick there and forgot to check the measurements, an old condo from 1969. All help is appreciated, thanks in advance 😀

You can hide it with lining, there will be air behind it but it won't be noticeable. Buy an MDF board and cut to size, mill a profile or add moldings depending on the desired appearance.

It looks like a concrete wall?

You should widen it if you want to fit in a 90 door.
