Microsoft Teams app design system

Quickly learn about the fundamentals of Teams app design. You can find comprehensive guidance and examples in the Microsoft Teams UI Kit (Figma).

Layout

Teams relies on a grid layout to ensure consistent and elegant relationships between design components. The grid’s 4-pixel base unit allows components to scale consistently across all display sizes in Teams.

Icons

Your app's primary icon can go a long way in conveying your brand to Teams users. Getting your icon design right is also important for publishing your app to the Microsoft Teams Store.

You also can use Fluent UI icons throughout your app:

Type

Teams uses Segoe UI for its type ramp and different font sizes and weights to help create hierarchy and ensure readability.
