How should animation speed be chosen for different amounts of content?

Animation speed should match the amount of information shown. When there is little information, animations should be fast. When there is a lot of information, animations should be slow.

The rule

Animation speed should match the amount of information shown.

When there is little information, animations should be fast. When there is a lot of information, animations should be slow.

Animation speed should match the content density. Content density means how much information is on the screen. If there is little content, animations should be quick. This helps the user move through the interface faster. If there is a lot of content, animations should be slower. This gives the user time to understand the new information.

A developer creates an app. One screen shows only a title and a button. The animation to this screen is fast. Another screen shows a long list of items and many details. The animation to this screen is slow. This allows the user to prepare for the new information.
