A font line is a term used to describe the thickness of a character in a font. In typography, there are several different terms used to describe the thickness of font lines:
- Hairline: A hairline font is very thin, with strokes that are barely visible.
- Thin: A thin font is slightly thicker than a hairline font, but still fairly light in weight.
- Light: A light font is slightly thicker than a thin font, but still not as heavy as a normal font.
- Normal: A normal font is the default thickness for a font. It is neither thin nor thick.
- Medium: A medium font is slightly thicker than a normal font, but not as heavy as a bold font.
- Bold: A bold font is much thicker than a normal font, and is often used to make text stand out.
- Heavy: A heavy font is even thicker than a bold font, and is often used for emphasis.
There are also many other terms used to describe font lines, such as ultra-light, semi-bold, and extra-bold. The specific terms used can vary depending on the font family and the design of the font.
