TypeTester!

Typetester is a website which allows you to test out different types in various styles. There are three columns in which you can choose various fonts, sizes, alignments etc in order to get a feeling for how certain fonts and styles interact with each other.

The strength of this website is in its simplicity. You don't have to search and around for the different options because they are all laid out in front of you. This makes it very easy to mix things up and get the style of type you want.
