What is front size means?

Font size refers to the height of characters in a typeface, typically measured in points (pt). A point is approximately 1/72 of an inch, so a 12-point font is about 1/6 of an inch tall. The font size affects readability and the overall visual impact of text in various media, such as print and digital formats. Larger font sizes are generally easier to read, while smaller sizes can fit more text in a given space.
