I love type, but my education in the field is still poor.
I've been wondering, what features of fonts i should be looking at, when i want to find a good serif/sans-serif pair? Color? x-height? Basic shapes of the letters, or shapes of the details?
I was thinking about pairing ITC Caslon with Cisalpin (Caslon for display, Cisalpin for body text) for a project. I based my choices on the following criteria:
1) The color is rather even between the two.
2) The x-heights are close to each other.
3) The basic shapes of the letters are in the vicinity of each other - though not outright identical. Caslon, for example, has somewhat smaller aperture. If I'm not mistaken, Caslon is a transitional typeface while Cisalpin is humanist.
