Research methods of measuring and sizing type.

Research should include topics such as

• the origin of the point unit and how it is used to measure type
• comparison of point, em, and pixel as a means of sizing text
• rules for determining leading (and the relation of x-height to leading)
• concept of tracking (or kerning).

Process/Skill Questions:

• What is the relationship between x-height and leading?
• How was the point size of a letter originally determined?
• How is tracking used to improve legibility?
• What is the importance of the style and size of type in a logo?
