I usually seek to do art above 2000x2000, and scan traditional stuff with more than 600dpi in order to "guarantee it looks crisp", but been pondering lately that I waste quite an unnecessary amount of space, which will likely add up considerably if I continue to do it that way, for drawings that more often than not will look 90% the same if they were drawn/scanned with less resolution. Not to mention I feel kinda bad wasting free space on sites I post in as well.
That being said, it makes me wonder how large other artists prefeer to make their art, and if it's a thing they think about or if it's just a random choice.
