Sans-serif fonts "read" bigger than serif because they tend to have proportionally larger x-heights. Unfortunately the "font-size-adjust" property isn't very well supported yet :(

Here I've deliberately quoted the CSS 2.0 version, as it's less subject to change than the CSS 3.0 equivalent. (It isn't in 2.1.) Intentionally de-linked because the necessary fragment # breaks under auto-linking.
There's a Firefox add-on that identifies fonts used on a site. It only works with named fonts; if the code simply says "sans-serif" the add-on won't tell you what specific font your browser is using. Presumably if you know enough to add a plugin you also know enough to find your browser prefs, where you yourself can tell the browser what to use.
