Thanks guys for your remarks.
I cannot get the window to add the size(s) like Patrick. I tried his
proposal to enter the sizes in the config file. Darktable reduces my
1734x1734 into aspect ratio 1 (square). To bypass the 'wrong' export
size I also crop my pictures 1 or 2px bigger.
About the solution from Willy. I know this but I do not want to scale my
pictures. I opted to crop them slightly bigger.

You might want to look in the Export selected module (2.3.12, p. 36 in
the Fine Manual). You can set the max size easily and darktable will
scale the image down appropriately.

I've had a similar problem before and solved it by exporting the
picture slightly larger (1 or 2px) and then cropping it with
ImageMagick (convert -crop or -geom or so..).

iirc:
<right><click> in the crop module and type your parameters
whereever I click on the crop module, I either get the drop down menu
for the various options or the slider for the rotation angle.
and I believe it is in the fine manual
It's not from what I can see:
https://www.darktable.org/usermanual/en/modules.html
But you can define your own aspect ratios in the config fwiw.
Cheers!
