Border principles

In SGDS, almost all components are rounded. Only specific components are exceptions to this rule.

Principles

Clarity

Borders should provide clear structure, aiding readability and navigation.

Subtlety

Borders should be minimal and unobtrusive, letting content take priority.

Border

SGDS border width is used to define structure and separation.

Default - 1 px

The default border width is used to illustrate the boundary of components and divide content.

Medium - 2 px

Medium borders are used to emphasise elements that primarily use borders for hover interaction, like input field.

Strong - 4 px

Strong borders are used to emphasise elements that primarily use borders for their structure, like tabs.

Radius

SGDS radius is used widely throughout our system. Each radius size is intentionally applied to select elements.

None and minimal (0 px, 2 px)

Used for sharp, structured designs with little to no rounding. Suitable for strict, grid-based layouts where clarity and precision are key.

  • Data tables (0 px for a rigid, structured look)
  • Dividers or separators (2 px for subtle softness)

Compact (4 px)

Provides slight rounding for a modern but understated look. Enhances usability while keeping a clean and structured appearance.

  • Icon button 24 px and 32 px
  • Tags, pills, or badges
Badge label

Standard (8 px)

The default radius for most components, balancing smoothness and sharpness. Works well across both functional and decorative elements.

  • Cards and modals
  • Tooltips and dropdowns
  • Inputs

Expressive (12 px, 16 px, 24 px)

Larger radius sizes that create a more distinct and friendly visual style. Used to emphasise key components and create a softer, more inviting look.

  • Modal and large callout banners (12 px, 16 px)
  • Feature cards or promotional sections (24 px)

Fully rounded (full)

Used for completely rounded shapes, ensuring a pill-like or circular appearance. Best for elements that need to stand out or convey a tactile feel.

  • Avatars and profile images
  • Floating action buttons (FABs)
