Creative Dojo shows how to make responsive text in After Effects that can auto-resize and scale.

There are plenty of instances where you want typography and text in Adobe After Effects to behave dynamically, automatically resizing itself as you work.

There are a few tools that do this kind of thing, but you can also choose to make your own. In this new tutorial from VinhSon Nguyen (Creative Dojo), you can learn how to create dynamic, auto-resizing, or responsive text within After Effects. 

“By manipulating some of the expressions, you can really customize and position your text anywhere and can apply the same concepts to make video/graphics resize dynamically as well.”
