Font size in word processing is measured in what unit?

Font size in word processing is measured in points. A point is a typographical unit of measurement that is equal to 1/72 of an inch. When you adjust the font size in a word processing application, you are typically selecting a specific number of points, which defines how large or small the characters will appear when printed or displayed on the screen.

This is a standard practice in typography and is utilized across various digital and print mediums. The other units mentioned in the choices, such as pixels, inches, and centimeters, are not typically used to measure font size. Pixels are often used for digital displays and screen resolutions, inches and centimeters may be used for physical measurements, but when it comes to specifying font sizes in documents, points is the universally accepted measurement.
