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.
Anatomy#
Options#
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.
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.
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.
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).
Value#
The value shows the progress of a system operation, from 0 to 1, such as downloading, uploading, processing, etc. This is not applicable when a progress bar is indeterminate.
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.
| Property | Values | Default Value |
|---|---|---|
| variant | default / over background | default |
| size | small / medium / large | medium |
| is indeterminate | yes / no | no |
| value | number (0 to 1) Not applicable when indeterminate. | 0 |
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#
RTL#
For RTL (right-to-left) languages, the fill of both the determinate and indeterminate progress circle continues to spin clockwise.
