I've tried to push designers into using the browser default font-size,
which is roughly 16px (for some reason all the browsers use that). It's a
nicely legible size in almost all the fonts I've seen use it, while 12 is
very small in some fonts. The only time I deviate from this is for mobile
devices which are generally held closer to the face than a desktop screen,
so the font will "appear" to be bigger.

I also suggest designers use the rem, em and percentage units when doing
everything that needs explicit sizes (borders, padding, margin, height,
width, etc.) so when a user scales the text, the design stays consistent
and text doesn't start spilling from one component to another.
