This article focusses mainly on pairing by classification. Here are a few other things to consider when pairing fonts: X-height: This is the height of the lowercase "x" glyph. You will notice that there is an imaginary line around where many lowercase letters line up at. This usually falls around the crossbar of an uppercase "A" and "H". Finding fonts with similar x-heights helps make a nice match. Glyph width: Finding fonts with very similar widths or very contrasting widths is also something to consider. If they are somewhere in between, it sometimes feels weird. Taking these attributes into consideration, in addition to their Era/Classification/Style really help in pairing fonts.
