Weight

Weight refers to the blackness or heaviness of a character, and generally ranges in scale from light to bold. Weights from one typeface to another can vary considerably, but they have relative meaning within a typeface family. Some typeface families have only a few weights. Bernhard Modern, for example, has only Roman and Bold, and Clarendon has three weights—Light, Roman and Bold. Other typeface families, such as Helvetica Neue and Interstate, have a huge range. Helvetica Neue has eight weights, from Ultra Light to Black.
