every place where you can print digital photos all the dimension options are dimensions of traditional 35mm proportions (4x6, 5x7, 8x10, etc)

is it possible anywhere to print a photo without having to crop for 35mm proportions? does paper in digital-photo proportions exist at all?

I find this very frustrating.....

(and: do frames exist in digital-photo proportions? when will the "print" part of digital photography catch up to the new photo dimension-proportions?? I don't get this......)
