Why use CSS Border Radius Generator

About this tool
Per-corner control
Different corner values can create asymmetric cards, speech-bubble shapes, badges, and organic visual treatments. Preview the shape before copying CSS.
Keep radius values consistent
A design system should usually have a small radius scale for buttons, cards, inputs, and modals. Too many radius values make an interface feel inconsistent.
Example usage
Input
Top-left 24px, top-right 8px, bottom-right 24px, bottom-left 8px
Output
border-radius: 24px 8px 24px 8px;
Practical guide for CSS Border Radius Generator
Best practices
- Use a small radius scale across buttons, cards, inputs, and modals.
- Preview asymmetric values in the component size where they will be used.
- Use large pill radii intentionally for badges, chips, and capsule buttons.
Common mistakes
- Using many unrelated radius values across one interface.
- Applying a radius larger than the component size without checking the shape.
- Forgetting that overflow and child backgrounds can hide rounded corners.

FAQ
What does border-radius do in CSS?
It rounds the corners of an element. You can apply one value to all corners or separate values for each corner.
How do I make a pill shape?
Use a very large radius, often 9999px, on an element with enough horizontal width.
Can each corner have a different radius?
Yes. CSS supports separate values for top-left, top-right, bottom-right, and bottom-left corners.
Should every component use the same radius?
Not always, but a small shared radius scale usually creates a cleaner and more consistent UI.
