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.

Design checklist#
All interactive states
Includes all interactive states that are applicable (hover, down, focus, keyboard focus, disabled).
All color themes
Works properly across all four color themes (lightest, light, dark, darkest).
All platform scales
Includes a desktop scale (UWP, macOS, web desktop) and a mobile scale (iOS, Android, web mobile).
Accessible use of color
Color is not used as the only visual means of conveying information (WCAG 2.0 1.4.1).
Accessible contrast for text
Text has a contrast ratio of at least 4.5:1 for small text and at least 3:1 for large text (WCAG 2.0 1.4.3).
Accessible contrast for UI components
Visual information required to identify components and states (except inactive components) has a contrast ratio of at least 3:1 (WCAG 2.1 1.4.11).
Content design
UI language and information design considerations have been incorporated into component design.
Defined options
Includes relevant options (variant, style, size, orientation, optional iconography, decorations, selection, error state, etc.)
Defined behaviors
Includes guidelines for keyboard focus, layout (wrapping, truncation, overflow), animation, interactions, etc.
Usage guidelines
Includes a list of dos and don'ts that highlight best practices and common mistakes.
Writing guidelines
Includes content standards or usage guidelines for how to write or format in-product content for the component.
Internationalization guidelines
Works properly across various locales and includes guidelines for bi-directionality (RTL).
Keyboard interactions
Follows WCAG 2.0 standards for keyboard accessibility guidelines and includes a description of the keyboard interactions.
Design tokens
All design attributes (color, typography, layout, animation, etc.) are available as design tokens.
UI kit
Includes a downloadable XD file that shows multiple options, states, color themes, and platform scales.
Generated UI kit
Includes a downloadable XD file, generated by code using design tokens defined in Spectrum DNA, and shows multiple options, states, color themes, and platform scales.
