Are font sizes universal?

There is no universally valid basis for body height usage and/or the font size this ultimately delivers. Font sizes are relative and a trained eye and experience are the most helpful tools to select the right size in addition to some basic values.

What font size is used in apps?

Mobile apps for Android use a minimum font size of 12 pixels, while iOS uses a minimum font size of 11 points. These app design standards ensure readability and are the most recommended font size for the main body text on mobile apps.

Are all 12 point fonts the same size?

Many people believe that 12 point fonts are all the same "size", and they "sort-of" are. All 12pt fonts use similar character widths, but they often have different character heights. For example here is the same text in 12pt Arial and 12pt Times New Roman (zoomed in on a Word document).

Is there a standard font size?

There is not a preferred font style; however, you can only use one style type (i.e., Times New Roman, Arial, Calibri, etc.). The font size must be either 11 point or 12 point size. Similarly, one size must be used for your body text.
