Squircles vs. round squares: everything designers need to know

Squircles and rounded squares are two similar yet distinct shapes that play an important role in design, with subtle differences in their curvature that can influence aesthetic choices. While a rounded square features 90-degree corners with rounded edges, a squircle combines elements of both a circle and a square, with continuous curvature, making it appear more circular and cohesive. Squircles are commonly used in various applications, from Apple iOS icons to traffic circles, due to their visually appealing and friendly appearance, as humans tend to prefer curves over sharp edges. The choice between using a squircle or a rounded square in design largely depends on personal preference and the specific needs of the project, as both shapes offer inviting and approachable qualities. Despite their differences, both shapes can be effectively incorporated into designs, and resources are available for designers interested in exploring squircles further.
