Question

What is the difference between 1/8", 1/4", 3/8" and 1/2" rounded corners?

Answer

The numbers on rounded corners refer to the radius of the curve, or how much of each corner gets rounded off. A bigger number means a larger, softer curve, while a smaller number keeps the corner closer to a sharp 90-degree edge.

RadiusLook
1/8"The subtlest, closest to a standard sharp corner with a gentle round
1/4"A moderate, balanced curve and a popular middle ground
3/8"Noticeably, clearly curved
1/2"The softest, most pronounced curve
  • Choose 1/8" for barely-there softening, 1/4" for a clean, modern look, and 3/8" or 1/2" when you want clearly curved corners.
  • Keep important text and logos away from the corners so nothing is clipped by the rounding.
