Border Radius

Last updated Feb 13, 2026

Border radius tokens define the level of rounding applied to corners across components in the Persona Design System (PDS). Instead of manually setting pixel values, tokens provide reusable references that keep corner styles consistent and predictable across the product.

PDS defines four types of border radius tokens, each representing a different level of rounding or shape:

TokenValueDescription
sm3pxsubtle rounding, used in small interactive elements like Checkboxes.
md4pxmoderate rounding, applied broadly across inputs, Menus, Banners, and Buttons.
lg8pxlarger rounding, used for bigger surfaces like Cards and Modals.
circle50%fully rounded, used for circular components such as Radio Buttons.

Using these tokens instead of hard-coded values ensures visual cohesion and makes it easy to update rounding consistently across the system.

Use the alias token that matches the component’s design guidelines rather than assigning a pixel value directly. For example, when styling a button, apply borderRadius.md rather than 4px. This ensures components remain consistent and easy to update if design values change in the future.
