When to Use


Use the busy indicator:

  • To indicate an unspecified amount of wait time that is longer than 1 second.
  • If progress isn’t detectable, or it’s not necessary to indicate how long an activity will take.
  • If only part of the application or a particular component is affected.

Don’t use the busy indicator:

  • If the operation takes less than 1 second.
  • If the progress can be measured. In this case, use the progress indicator instead.
  • To indicate that a larger part of the screen is loading (for example on page load). Use a placeholder loading animation instead.


The busy indicator component consists of two parts:

  1. Busy icon: Animated dots that indicate the ongoing operation.
  2. Text (optional): Provides additional information about the ongoing operation.


If the space where the busy indicator is to be placed is limited, avoid using a busy icon text. For example, don’t show a text if the busy indicator appears near a button in a small area. This can result in the busy indicator text appearing on top of the button text.

If you opt to display a text, place the busy indicator within a container, such as a toast or dialog, and allow it to wrap. This ensures that the text is always readable.

Size Variants

The busy indicator comes with three predefined sizes:

  • Small: Use inside areas smaller than 3×3 rem (for example, when reloading images or inside small components like compact table rows).
  • Medium: Use inside areas larger than 3×3 rem (for example, inside a list item, tile, dialog, or a block overlay within a component).
  • Large: Use inside a full screen block overlay.
