Export a 72ppi Darktable 5.0

Software

Hello;

I am using Darktable 5.0, and I have a doubt that I do not just see, I need to export images to 72ppi and I can not do it, I always export them 300ppi or higher. How can I do it? Any suggestions?
Regards

You can change the “set size” option in the export module to “in inches” or “in cm” and that’ll let you set a ppi. However, PPI is just some metadata and what actually matters is the number of pixels you’re exporting.

simply multiply the expected size in inch with 72 to get the pixelcount you need for exporting.

Thank you all for commenting I am ok with the solution to print. But what if what I want to get for file in pixels is long side 1920px and 72ppi how could I configure the export module so that as a result it exports me a file of 1920px and 72ppi.
I am learning how to use the export module, sorry for these questions that may be a bit silly for those who already mastered it.

Regards

simply enter 1920 as export size for the long size (or both sizes if you mix portrait and landscape orientation) and then use an external exif editor to type a ppi value as you like it. darktable doesn’t bother about ppi. It exports pixels …
1920px at 72ppi and 1920px with 300ppi ist the same output size.
