It doesn't sound like a lot, but it adds up.
It actually gets worse than that. CSS is loaded synchronously, i.e., when the <link> tag is found. This means that those extra 20 kB will be tacked on before you even see the page content. On slower connections, this may become quite annoying. All asynchronous options seem to require some form of JavaScript hack (cf. https://www.filamentgroup.com/lab/async-css.html).
