Font Size Comparison Chart

View this page in different monitor resolutions.

Wondering how to correspond XHTML font sizes (1, 2, 3, 4, 5, 6, 7) to CSS pt and px configurations? Like so many areas in web technology, the answer is ... it depends!

Since the pt is browser dependent (for example, 12 pt looks different when various browsers are used to display web pages) and the px is monitor-resolution dependent, there is no hard and fast rule for correspondence.

CSS fonts can also be configured using "ems" (relative size -- the term is borrowed from the print industry)
