Definition of Baseline in Graphic Design

In graphic design and typography, the “baseline” is an imaginary line upon which most letters in a typeface sit. It provides a consistent reference point for aligning and spacing characters within a line of text.


The baseline serves as the foundation for establishing vertical alignment and maintaining visual consistency in typography. It is essential for creating readable and well-organized text layouts in various design projects, from print materials to digital interfaces.
