Hmm I tried to reproduce this and on my machine (12.1 on Mac OS X ventura), it works correctly. landscape is 20 cm wide and (depending on ratio much smaller in height) and portrait images come out 25 cm high and some other width as long as it is less than 20 so exactly as the documentation says. Not sure why this wouldn't work as described. The width and height settings define a box that your image needs to fit in. There used to be a bug many many versions ago that did what you described where it would not accurately take image rotation set in camera into account and you ended up with reversed image sizes as you describe but that bug is long squashed.

Export sizing defines a "to fit within" containing box, rather than a "to entirely fill" outcome.

It is only when the image aspect ratio (as cropped) exactly hits the same proportions as the export width and height, that an image can be produced which meets both those numbers, and thereby "fills" this bounding rectangle.

If you don't want to alter the crop of your image just for this purpose, you can make a temporary virtual copy and change the aspect ratio of that. Or you can subsequently step back in History panel, and reverse this change.

If you want to export to a specific height AND a specific width, then the current crop must be to the same ratio. Otherwise odd things will happen.

For landscape i want to export, e.g. with 20 cm and for portrait i want to export high 25 cm. This will fill a bookside which is 22 by 28 cm in portrait.
