Digital Print Sizes

The paper sizes I use for black and white prints done in the darkroom is 8x10, 11x14, and 16x20 inch and printed with a half inch border . The darkroom papers come in these sizes and its what I have used for many years. Now all of the sudden the paper manufactures, some who make standard size darkroom papers, make their digital ink jet papers in different sizes.
The lower photo shows my small and medium size prints. The small have a 7x10 inch image on 8.5x11 inch paper. The larger print, what would be the medium size, is a 9x13 inch image on 11x17 inch paper which is the 17x22 inch sheet cut in half. The largest size will be on the full sheet 17x22 inch paper.
The upper photo shows the two smaller sizes matted. The small print is matted with a 14x18 inch mat and the medium size is matted with a 16x20 inch mat. That means these two sizes can be framed with the same size frames as the black and white darkroom prints are.
