Corner Radius: Live Preview

Dial in the perfect corner radius and preview it live on real UI shapes — pixel-precise, every time. Drag a single slider and watch the corner radius update instantly on a real, scalable UI shape. Stack two shapes and judge subtle radius differences the way your eyes actually will. Read exact pt, px, and continuous-curvature numbers — copy them straight into your design tool. Tune fill, stroke, and shadow so the preview mirrors the surface your component will live on. Everything stays on your device.
