# What is a Resize Trigger?

A Resize Trigger is a feature that ensures dynamic text elements in your video automatically scale to fit their designated area—no matter how short or long the content is.

This is especially useful in personalized videos where text length can vary depending on the viewer’s data (like names, cities, or product names). Instead of manually adjusting each design or risking awkward overflows, Resize Triggers allow you to maintain a clean, consistent layout across all variations.

### How It Works

When you apply a Resize Trigger to a text layer:

* The system monitors the text length and resizes the font or adjusts spacing accordingly.
* It ensures the text never spills out of its container, and maintains design integrity.

This is particularly important when using:

* Names of different lengths (e.g., “Jo” vs. “Alexandrianna”)
* Dynamic tokens from CRM data
* Multilingual content with varied word lengths

### When to Use Resize Triggers

* In templates designed for mass personalization
* When working with dynamic tokens or data-bound text
* When using scalable design systems that need to maintain alignment and spacing rules

### Best Practices

* Test your design using sample data sets with short, average, and long inputs.
