Border Radius Architect

Create perfect rounded corners for your UI components with professional-grade precision and real-time visualization.

Corner Matrix
20px
CSS Property
border-radius: 20px;

Individual Logic

Toggle between uniform radius for all corners or fine-tune each specific corner for asymmetric, organic shapes.

Real-time Synthesis

See your architectural changes instantly in the high-contrast preview window as you manipulate the geometric sliders.

Clean Deployment

Instantly export production-ready CSS properties that follow modern web development standards and shorthand conventions.

Built With Care

“The generator outputs the standard CSS shorthand: one value for uniform corners or four values in top-left, top-right, bottom-right, bottom-left order. The live preview applies the property to a real element, so you see exactly how the radius renders before copying it to your stylesheet.”

Corner Radius Design Guide

Generate CSS border-radius values with a live preview, from perfectly uniform corners to fully asymmetric shapes. Adjust four corners independently with sliders from 0 to 200px and copy the finished declaration. Runs in your browser for instant visual feedback.

Real Ways People Use This

Button Styling

Create pill-shaped buttons with a fully rounded radius or softly rounded buttons that match a design system.

Card Components

Give containers gentle rounding that softens the UI without looking toy-like.

Avatar Images

Set a 50% radius on square profile photos to turn them into perfect circles.

Input Fields

Match form inputs to button corners for a cohesive design language.

Organic Shapes

Combine different per-corner values for asymmetric panel shapes and visual interest.

Important Notes
  • Values above 50% on non-square elements produce elliptical corners, not circles.
  • Border radius does not clip a border-image; you may need overflow hidden on the container.
  • Very large radius values are visually clamped to the element's dimensions.
Quick Checklist
  • 1Test the generated radius on the actual component size, not just the preview.
  • 2Verify the shorthand renders correctly in your target browsers.
  • 3For circles, confirm the element has equal width and height before copying.
