It takes an hour to export them all, so I didn't want to confirm the actual results. I'm not sure the JPEG files are linear in there diskspace needs. Flickr is telling me that 13,382 images on their site, all at 2048px wide, are using 25.9GB this morning. So, maybe it is a factor of 4x?
If you double the width the photo will look strange unless you double the height at the same time.
And you’re right that the jpg compression will not respond linearly but I don’t think it will make a large difference.
