What is the Border Radius Generator?

Set rounded corners visually — the same on every corner or different on each — and copy the shortest correct CSS.

How it works

How to use the Border Radius Generator

3 simple steps. No experience needed.

What can you use it for?

  • Round cards, buttons and images.
  • Create pill or leaf shapes with uneven corners.
  • Match the corner radius from a design.

Same or different corners

Link the corners to round them all equally, or unlink them to set each one between 0 and 200 px — useful for tabs, chat bubbles and cards attached to one edge.

Making circles and pills

On a square element, a radius of half its width makes a circle. On a wide element, a radius at least half its height gives pill-shaped ends.

FAQ

Frequently asked questions

What order are the four values in?

Top left, top right, bottom right, bottom left — clockwise from the top left.

Why is the output sometimes a single value?

When all four corners are equal, one value is the shortest correct CSS. Different corners need two to four values.
