When designing or selecting icons for a project, it's essential to keep the design elements like corner sharpness, geometry, and shapes consistent. Consistency in these aspects helps users quickly recognize and understand the icons' functions, contributing to a smoother user experience. If you opt for sharp-cornered icons, maintain that style throughout all icons in the interface. Mixing styles, like having some icons with rounded corners and others with sharp ones, can disrupt the visual flow and confuse users.

Uniform icon design not only makes the interface more intuitive but also reinforces brand identity. Users appreciate a well-curated visual language, making them more likely to engage with your interface comfortably.
