Actually, I was thinking of CSS  Pixel breakpoints as the intermediary for
developers. If we consider % of height and /or width as the factor, then
isn't CSS pixel the unit of measure?

Now consider users with low visual acuity (one big population of many). To
them, the screen would look best as a mobile phone in landscape (for L-R
and R-L languages). Now mobiles are built for closer viewing so that 16 px
matches 12pt approximately (true spacial  points 1/72 in). For the larger
screen low visual acuity view 16px will serve the same role. What multiples
of 16  will fit on the screen. What font size can be offered to create an
experience that is comparable to refreshable braille.  Can't we say for
pixel space x do y. I think we can, and give a very  meaningful
quantitative guidelines right now.

I never used a mobile with a cctv. I do put mine under my super magnifying
glass at a table. Interesting.
