You might wanna consider the recommended guidelines for here too:
https://commons.wikimedia.org/wiki/Commons:Image_guidelines#Quality_and_featured_photographic_images

Although the guidelines apply to quality and featured images, I think the underlying reasons check.

At least, a 2MP resolution can be considered the minimum. I don't know if any image below that threshold will look good enough these days on screens.

Hello!

I am in touch with a museum that is thinking of uploading images to Commons. They are a bit uncertain about uploading high resolution, but I told them the resolution they need to upload just needs to be good enough for illustrating articles without being pixellated. The thing is, I am unsure about the minimum size of such an image. I tried poking around the instructions but didn't find a direct answer.

Do you know which size is "the minimum" that can be accepted on Commons?

Thanks a lot for your help!

Warm wishes,
