fonts and faces


. About Fonts and Faces

1.     A font is a collection of characters of a particular font size, font style of a typeface. For example, within Times New Roman, however, there are many fonts to choose from -- different sizes, italic, bold, and so on.

2.     The term font is often used incorrectly as a synonym for typeface. For example, Arial is a typeface and Arial 12 point Bold is a font.

3.     Typefaces are the graphic representation or the shape of the alphabet, numbers, and special characters and usually vary by type sizes and styles. For example, Times New Roman, Arial, and Century Gothic are few examples of typefaces.

4.     Typical font styles are bold, italic and underline.

5.     Font sizes are usually measured in points where one point is equal to 0.138 inches or 1/72 of an inch. The font size is determined by measuring between the top of a capital letter to the bottom of descenders in letters such as g and y.
