Reply To: font-family: Arial, Helvetica, sans-serif; is enough?

What about mobile? Do you still set it at 20px? Open Sans is very legible and readable at small sizes.

Yeah, maybe. I was just tinkering with it on https://www.google.com/fonts/specimen/Open+Sans and setting a font to 16 made it look very tiny. But testing it in Codepen seems fine: http://codepen.io/senff/pen/CfGut

I should stop talking about fonts and typography, I obviously don’t know anything about it ;)
