Font size or text size is a number that measures the size of characters (such as letters, numbers, and punctuation marks) on a screen or printed page.
How is the font size measured?
A font is often measured in pt (points). Points dictate the height of the lettering. There are approximately 72 (72.272) points in one inch, or in 2.54 cm. For example, the font size 72 would be about one inch tall, and 36 would be about half an inch. The image shows examples of font sizes ranging from 6 pt to 84 pt.
Another common unit for measuring font size is a pica, abbreviated as pc. One pica is approximately 1/6 of an inch, so a font size of 6 pc would create characters with a maximum height of approximately one inch.

How to change the font size for desktop icons
To change the size of text for desktop icons, you need to increase or decrease their image size. When you resize desktop icons, their font size follows suit.
Why are most of the fonts everywhere small?
If you have a high-resolution computer display, it can increase the quality of displayed images by increasing the number of pixels displayed (more DPI (dots per inch)). However, increasing the resolution may also decrease the size of some UI (user interface) elements including fonts, letters, numbers, and icons.
Most modern operating systems including macOS and Windows 10 and 11 automatically scales fonts to properly legible sizes at high display resolutions. If not, you may need to adjust the operating system display scaling settings.
To adjust OS (operating system) display scaling settings in Windows or macOS, go to:
Windows 11: Settings > System > Display > Scale & Layout > Scale.
Windows 10: Settings > System > Display > Change the size of text, apps, and other items.
macOS: Apple Menu > System Settings > Displays > Resolution.

Some of these dimensions include xx-small, x-small, small, medium, large, x-large, and xx-large. Font size may also be specified using Point, Pica, Inch, Centimeter, Millimeter, em, and percentage.
