The line thickness of felt-tip pens depends on the design of the tip. As a result, there are types of markers, such as those with a triangular-cut tip, where the line thickness falls within a range rather than being a fixed value. On the other hand, cone-tipped and fine-tipped felt-tip pens have a fixed line thickness. However, thicker cone-tipped markers can vary in line thickness depending on how the pen is angled and the pressure exerted while writing
