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

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. Radius Look 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.

The number is the corner radius: 1/8" is a subtle round, 1/4" a balanced curve, 3/8" clearly curved and 1/2" the softest, most pronounced.

| Radius | Look |
| --- | --- |
| 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.
