I thought I’d pull this out for reference/expansion. Original data courtesy of Fishbreath’s great post on his P-09 Carry Optics Build. It’s still sorted by mm height/$100, but it’s also a handy reference of window sizes.
For the area column, the sights are assumed to be rectangular (except for the C-More SlideRide, which is circular), which is an invalid assumption, but you get what you pay for.
