Creating Harmony When you design with type, the goal is to create harmonious relationships. For a subdued look, you might use typefaces of similar weight and style within the same family and not vary the sizes much. For a more dynamic but still harmonious look, you can combine typefaces that are clearly different and vary the weight and style. The size and location of the type impacts the relationship as well. Try mixing type from the same font family or by mixing type from two families such as a classic serif and a clean, bold sans serif.
