Progress circle

Progress circles show the progression of a system operation such as downloading, uploading, processing, etc. in a visual way. They can represent determinate or indeterminate progress.

Example of an indeterminate progress circle in action, just spinning and spinning.

Options#

Key example showing both determinate and indeterminate progress circles in default variant.

Default variant#

Progress circles are used to visually show the progression of a system operation such as downloading, uploading, processing, etc. By default, progress circles have a blue fill that shows the progress.

Example of an 'over background' progress circle.

Over background variant#

When a progress circle needs to be placed on top of a colored background, use the over background variant. This progress circle uses a static white color regardless of the color theme. Make sure the background offers enough contrast for the progress circle to be legible.

Two key examples of progress circles, showing value, min value, and max value. First example, file upload. Value 15, min value 0, max value 18. Second example, filter processing. Value 0.92, min value 0, max value 1.

Value, min value, max value#

The value is the progress of a system operation (e.g., downloading, uploading, processing) within the progress circle’s range, from the min value to max value.

The min and max values can also be customized appropriately for whatever the progress circle is showing. By default, the min value starts at 0 and the max value is set to 100.

These values are not applicable when a progress circle is indeterminate.

Examples of the size variants of progress circle, showing small, medium, and large sizes.

Size#

Progress circles come in 3 sizes: small, medium (default), or large. These are available to fit various contexts. For example, the small progress circle can be used in place of an icon or in tight spaces, while the large one can be used for full-page loading.

Examples of both a determinate and indeterminate progress circle.

Indeterminate#

A progress circle can be either determinate or indeterminate. By default, progress circles are determinate. Use a determinate progress circle when progress can be calculated against a specific goal (e.g., downloading a file of a known size). Use an indeterminate progress circle when progress is happening but the time or effort to completion can’t be determined (e.g., attempting to reconnect to a server).

Table of options#

From the design point of view, each component has a number of options. These options and their names are platform agnostic, and each implementation should adapt these to fit into their framework.

Usage guidelines#

Use progress circles for loading views#

Medium and large progress circles are optimized for large areas with no space constraints. Use them for loading content into views (e.g., web pages, panels, etc.)

Use small progress circle when space is limited#

Small progress circles are well suited when space is limited both vertically and horizontally, such as in buttons, menu items, and input fields.

Internationalization#

Example of a determinate and indeterminate progress circle in RTL layout, where the fill continues to progress clockwise.

RTL#

For RTL (right-to-left) languages, the fill of both the determinate and indeterminate progress circle continues to spin clockwise.
