Where to use it
An indeterminate progress bar says “working on it” without promising a time. It fits the top edge of a web app while the next page loads, the header of a dashboard refreshing its charts or the space under the search box of a flight comparison site. It stays out of the way and still shows life.
Thin works best: three or four pixels pinned to the top of the screen are barely noticed, yet reassuring. As soon as you know the real percentage, switch to a determinate bar so people can see the end coming.
