A typeface is a specific design of letters and numbers, either in print or on a computer. When you choose a typeface for your resume, you'll want something that's businesslike and easy to read.
You can think of typeface as another term for font (the two words are often used interchangeably), although it's more accurate to call a typeface a "font family," a group of fonts with similar designs. Typefaces have official names like Comic Sans, Garamond, and Helvetica. If you dream of inventing your own typefaces, you may want to become a type designer. You'll be adding to the thousands of typefaces in use today!
