Many websites and other online applications are making a mistake by using body text that is simply too small.
What’s too small? And what’s too large? Well, Christian Miller of Medium has a rather complex answer for that question.
More importantly, why should your text be larger? Perhaps the most obvious reason: It makes your text easier to read from any distance. And if your text is easier to read, your web application will also be easier to use.
A slightly less obvious reason that Miller discusses is that “Larger font sizes on headlines can elicit a much stronger emotional connection, and the same applies to body text.”
