That sounds like a good idea. I will figure out how to create such a 
style. I will make a 1734x1734 crop when I am on a 100% picture for this 
style. In the mean time I can use the copy/paste of the 'crop portion' 
of an image with the correct size. How can I enter an RFC to have this 
option in darktable?

Yes, the information you can enter manually in the cropping module is an aspect 
ratio, not an actual dimension. You can enter dimensions in the export module, 
which is a bounding box that the image will be scaled to fit within. Neither of 
these do what you seem to want to do, which is take an exact sized crop from 
your image.

This can be difficult with larger-than-screen images in darktable... you need 
to view the image at 100% for the cropping guide movement to be pixel-precise, 
which is very awkward, but that's the only method I've found for the times when 
I've wanted to do this. The alternative is allowing a margin, then final 
cropping with an external application, which isn't terribly convenient.
That might explain why there is a difference between the crop size that 
you select and what you get.

fwiw, I cannot either.  I believe the  is only for angular
positioning.  but it is possible to crop one image, go to lighttable, copy
crop portion of history stack and paste it to other images.  then edit the
other images to reposition the crop to desired location and you will have
the same crop parameters.  one could craft a style of only crop at
particular parameters and use that to make a group of photos have
"exactly" the same crop.

just successfully test the copy, paste.  did not bother to make a style.

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.

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:
 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.

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.
