About This Tool

The Border Radius Generator lets you set each corner of a CSS element independently — top-left, top-right, bottom-right, bottom-left — and previews the shape in real time. It handles both uniform and asymmetric border radii and generates the minimal CSS property needed. Free, no account, runs in browser.

How to Use

  1. 1

    Adjust each corner's radius using the individual sliders or input boxes.

  2. 2

    The preview shape updates live to show the exact rounded corners.

  3. 3

    Copy the generated border-radius CSS property for your stylesheet.

Frequently Asked Questions

Can I create an ellipse shape using border-radius?

Yes. Set all four corners to 50% to create a perfect ellipse or circle (on a square element).

What is the difference between border-radius: 10px and 50%?

px values create a fixed curve regardless of element size. % is relative to the element's dimensions — 50% creates a circle on a square element.

Is this border radius generator free?

Yes. Completely free with no account required.
