Border Radius Generator
Set each corner radius with live preview. Link corners, px or % units, presets, copy or download CSS.
Values follow top-left → top-right → bottom-right → bottom-left. Equal corners collapse to a single value.
How it works
Choose a preset or unit
Click a preset for common shapes: rounded card, pill button, circle, or asymmetric corners. Switch between px and %.
Adjust corners
Use linked mode to set all corners at once, or unlink to edit each corner independently.
Copy or download CSS
Preview updates live. Copy border-radius: …; or download border-radius.css.

Questions
What does Border Radius Generator do?
It builds CSS border-radius values for all four corners with sliders and a live preview.
What order are the corners in?
CSS shorthand goes clockwise from top-left: top-left, top-right, bottom-right, bottom-left.
When should I use percent?
Percentages are relative to the element size: 50% on a square makes a circle. Pixels give fixed corner sizes.
What does Linked mode do?
When linked, moving one slider updates all four corners to the same value.
