Because of the wide range of settings and equipment that people might be using to access the World Wide Web, there is no “best font size“. Font sizes should be specified using relative units like percentage or EM, (in external CSS files) since these will allow the user to adjust font sizes up or down to suit their own requirements. Avoid using graphics of text, as this locks the text size, and makes it impossible for users to change it.
