Geometric sans-serif is a type of typeface characterized by clean, simple lines and shapes that are often based on geometric forms like circles and squares. This style emphasizes clarity and modernity, making it popular in various design applications, including branding and digital interfaces. Common examples of geometric sans-serif fonts include Futura, Avenir, and Montserrat. These typefaces are often used for their legibility and contemporary feel, making them suitable for both print and screen designs. Their uniform stroke widths contribute to a cohesive and balanced appearance in typography.
