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.

Each pixel on the screen can be represented in the computer or interface hardware (eg. a graphics card) as values for red, green and blue. These values are converted into i
