What is font?


Let’s notify the terms used in this article.

And the first and the main question is, what is font?

Font is the set of graphical representations of symbols. The way a font looks depends on the font’s parameters such as type family, typeface, font proportions, etc.

Glyph - is a graphical representation of a symbol. It is aimed to depict a distinguished character. The glyph is a unique shape, design, or way it looks. It is how the character is rendered in a particular font.

In the image below, you see the glyph @ rendered in different fonts.

Typeface - is a specific design of a font. It has size, weight, width, slope, and other variations. It is often confused with the term font. The point is that fonts have particular (fixed) parameters. So the difference is in having variations. Therefore every variation in a typeface is an individual font. The term typeface is also often mixed up with the type/font family.

So, what is font family? Font family is a group of related, similar in design typefaces. The members of a family have a common name.

The image below will clarify to you the difference between font, typeface and font family.
