Calibri, we hardly knew ye. Microsoft’s default font for all its Office products (and built-in apps like Wordpad) is on its way out and the company now needs your help picking a new one. Let’s judge the options!

You probably don’t think much about Calibri, if you think about fonts at all, but that’s a good thing in this context. A default font should be something you don’t notice and don’t feel the need to change unless you want something specific. Of course the switch from Times New Roman back in 2007 was controversial — going from a serif default to a sans serif default ruffled a lot of feathers. Ultimately it proved to be a good decision, and anyway TNR is still usually the default for serif-specified text.
