I've always liked ExoticSilicon's design, but not until this post did I realize their smart bit of CSS for default font size:

  font-size: min(max(1em, 1.3vw), 1.3em);

Which explains why it looks just right on my high-DPI Chromebook even though I haven't configured a big enough default font size for the browser.

This is going to be the default font-size for all of my websites now (preceded by a fallback for maximum compatibility of course).
