Sans font to go with Bitstream Charter

Question

I've been using Bitstream Charter (\usepackage[charter]{mathdesign}) for a while now. For my German documents, I looked into KOMA today and found that the scrartcl document class would be a good replacement for article.

It uses sans fonts for the headings and serif font for the text. I got the following warning:

LaTeX Font Warning: Some font shapes were not available, defaults substituted.

As it seems, I got the Computer Modern Roman sans font for headings, but Charter for the text. I tried Bitstream Vera Sans (Bera Sans, \usepackage[scaled]{berasans}). It looks better than before, but I am not sure whether this is a good font to go with Charter:

Is that the matching font or is there a nicer one? It seems pretty thick, especially in the page title.

For comparison, here is plain Computer Modern Roman with article:

And just Charter with scrartcl:

Answer 1

I think it's not quite a LaTeX question, but Bera looks nice. Linux Biolinum would be a nice option. But you don't necessarily need to use a sans anyway. If you used xelatex you'd have plenty of options, though.

Answer 2

The most useful website ever, WolframAlpha, uses Bitstream Charter with Bitstream Vera in its results, which I feel looks nice. (Charter for all math and numbers and Vera for pretty much everything else) Vera is not supported by LaTeX, but luckily there is a clone—Arev—that is actually comes with most packages.
