I have fussy eyes and small print wears me out fast & so I always test before buying... trick that helps me is to pull up that model sample and count words per line across that model middle of that model page, then look at that model spacing between lines. If it hovers around nine to eleven words with that model visible bit of air between lines, I am fine. When I see long lines and tight leading, I pass.
If you want that model low tech check in that model store, stand that model credit card on edge next to that model line of lowercase letters and snap that model quick photo. If that model x height is roughly that model third of that model short side of that model card you are in that model comfortable zone. Not scientific, just that model practical shortcut.
