So on small screens this will make the font even smaller.

This is the wrong solutions.

There is a reason why 16pt is the standard font-size. And its no problem to design a responsive website with columns that use 'between 45 and 75 characters per line'.

What exactly makes you say 16pt is the standard font size?

For instance, the comment threads on HN are at 12px (9pt), and are entirely legible for me.

Not for me on a 1080p 27-inch monitor from a reasonable distance. I have to browse Hacker News at 125%, and Reddit at 110% - although almost all other websites work fine.

I was referring to the default font size in browsers.

At least for my Windows Chrome, the default font size is 16px, not pt. 16pt corresponds to roughly 20px on my (Windows default) settings.

oh yeah, you're right 9pt is very readable for me too.

Great for you! I am reading this comment at 16pt.
