Circle loaders show the progression of a system operation such as downloading, uploading, processing, etc. in a visual way. They can represent determinate or indeterminate progress.
Circle loaders are used to visually show the progression of a system operation such as downloading, uploading, processing, etc.
When a loader needs to be placed on top of a colored background, use the over background loader. This loader uses a white opaque color no matter the background. Make sure the background offers enough contrast for the loader to be legible.
Circle loaders come in 3 sizes: small, medium (default), or large. These are available to fit various contexts. For example, the small loader can be used in place of an icon or in tight spaces, while the large one can be used for full-page loading.
This shows the percentage of a system operation’s progression, such as downloading, uploading, processing, etc. This is not applicable when a circle loader is indeterminate.
A circle loader can be either determinate or indeterminate. By default, loaders are determinate. Use a determinate loader when progress can be calculated against a specific goal (e.g., downloading a file of a known size). Use an indeterminate loader when progress is happening but the time or effort to completion can’t be determined (e.g., attempting to reconnect to a server).
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.
default / over background
small / medium / large
Not applicable when loader is indeterminate.
yes / no
Medium and large circle loaders are optimized for large areas with no space constraints. Use them for loading content into views (e.g., web pages, panels, etc.)
Small circle loaders are well suited when space is limited both vertically and horizontally, such as in buttons, menu items, and input fields.
For RTL (right-to-left) languages, the fill of an indeterminate circle loader continues to spin clockwise.
For RTL (right-to-left) languages, the fill of a determinate circle loader continues to fill in clockwise.
