Yes, good catch. This should be:
oe_photo_12r_12x15in [HP20210302]

Yes, the width is usually the number before the "R" (3R is the exception).

Both of the following sources list 24R as 24x31.5:
https://en.wikipedia.org/wiki/Photo_print_sizeshttps://mainthebest.com/sizes/24r-sizes/
which would be 7.5 inches larger than the width (just like 22R), so this entry should be:
oe_photo_24r_24x31.5in [HP20210302]
Unfortunately, I'm having a hard time finding a definitive source for the larger "standard" sizes... :/

Yes, several of these metric sizes are close to existing English sizes, but not exactly.

Let's see what Smith can find out from his end...
