The secret formula for Apple's rounded corners (2023)
2 days ago
- Apple's products use rounded corners and squircle shapes for durability and safety, avoiding sharp edges.
- Rounded corners trigger a positive neural response due to the Contour Bias, reducing amygdala activation.
- Apple follows a design principle that objects closer to the human body are rounder, like AirPods and Apple Watch.
- Roundness scores were measured by dividing the curve diameter by the side length, revealing a consistent pattern across product lines.
- Desktop devices have 0% roundness, while personal items like AirPods Pro and Apple Watch approach 50-100% roundness.
- The pattern suggests Apple intentionally applies this formula to all products, as seen with the highly curved Vision Pro.
