CSS Border Radius Generator

Generated CSS

  border-radius: 20px 20px 20px 20px;
}

Generate CSS Border Radius

The border-radius property rounds the corners of an element. This generator gives you independent control of all four corners with a live preview, then copies the exact CSS — from gentle rounding to pill shapes and organic blobs.

How it works

  • Each corner can have its own radius
  • The shorthand order is top-left, top-right, bottom-right, bottom-left
  • Equal values on all corners give a uniform radius
  • Large values create circles and pills

Pixels vs. percent

Pixel radii stay fixed; percentage radii scale with the element. A border-radius of 50% on a square makes a perfect circle.

Private & Processed Locally

The CSS is generated in your browser; nothing is uploaded.
