About Border Radius Generator

Generate border-radius values visually and copy them straight into your CSS. Use it for buttons, cards, images, avatars, and playful “blob” UI shapes.

How to use

Pick a preset or adjust the corner sliders.
Enable Elliptical to control X/Y radii separately.
Copy the generated value (or a full CSS snippet).

CSS syntax tips

4 values: border-radius: TL TR BR BL;
Elliptical: border-radius: TLx TRx BRx BLx / TLy TRy BRy BLy;
Percent units scale with the element size and are great for fluid rounding.

Good use cases

Designing buttons and cards that match a brand style.
Creating avatar crops (try 50%).
Making organic shapes for hero sections and backgrounds.
