When drunk, reading Korean characters on mobile becomes a herculean challenge.
That said, CJK characters tend to be printed a little larger. For example, if you look at this line (예를), many apps/browsers will have slightly larger vertical spacing for the line due to the CJK characters being 10-15% larger than Roman ones.
Edit: I just realized you might be blind, so you won’t be able to see the line has more vertical spacing. But trust me, it does!
