When combining fonts, choose fonts that contrast each other or come from the same historic period. When mixing fonts in the same paragraph, select fonts with similar characteristics like x-height and cap height. If mixing two fonts in the same paragraph, make sure they have the same x-height so it does not appear jarring to readers. Bodoni and Futura seem like unlikely pairings but can work together due to their vertical strokes. Lucida Sans, Lucida Bright, and fonts designed to go together are good pairing options.
