There are a few measurements that can be used when setting up your document. • The Point - There are 72 points to an inch. All type is designated in points. Typefaces may be different sizes from 4pts to 144pts. Line spacing is also measured in points (eg. 2 points of leading, kerning, etc...) •The Pica- There are 12 points to 1 pica, and approximately 6 picas to 1 inch. The length of the line (linear measurement) is specified in picas, as well as the depth of the area. eg. a block of copy is to be set 10 picas wide by 20 picas deep. Inches are never used in type measurement. •The em- It is the square of the type size. It is not part of the point system. •The Agate line-line measurement used by newspapers to sell advertising space. There are 14 agate lines to an inch. The width of the column can vary from paper to paper.
