User Guide: Text Font Size

In CKEditor the Size determines how big or small a font used in the document text will be. The system administrator may customize the set of available font sizes to the needs of a particular CKEditor installation, however, by default the following values are available: 8px, 9px, 10px, 11px, 12px, 14px, 16px, 18px, 20px, 22px, 24px, 26px, 28px, 36px, 48px, and 72px. Depending on the needs of the system, font sizes may also be defined in a descriptive manner, like Very small or Bigger.

To change a font size for a text fragment, open the Size menu by clicking the Size button on the toolbar. The font size drop-down list contains a number of sizes that you can use. To make the choice easier, the items of the list are displayed in a font size that they represent, giving you a preview of what the text will look like.

A font size can be applied to the whole document, a paragraph, or a text fragment of arbitrary length — even a single letter. Do note, however, that for aesthetic and readability reasons it is recommended not to combine too many different font sizes in one document.
