Just curious what you all do when selling prints.

Most of my photos are un-cropped. So they are in the 2:3 ratio.

So how do you all sell these images? In what sizes?
Especially when the most common precut mattes are 8x10, 11x14, 16x20.

For example, if I want to maintain the 2:3 ratio and not add a border - then I was thinking about selling sizes 6x9, 8x12, 16x24. But then, it seems, the customer would have a harder time finding a precut matte.


What sizes are typically sold?

Thank you!
