Dynamic Scaling

Text Animator achieves uniform effects result on different screen resolutions by default, and it is recommended that you keep this feature enabled.

Explanation

Your players will most likely have different screen sizes (their devices, from mobile to monitors etc.) which means that moving a letter of "50 pixels" might seem too much or too low, while as a designer you'll want an uniform experience/result for everyone, exactly as you intended. This is why we strongly advise to keep "Use Dynamic Scaling" enabled, and edit values based on your current computer font size (so whatever changes later, it'll keep the same uniform ratio).

• Reference Font Size: represents the size where objects behave as expected. As a reference, you can pick the font size in your unity editor while you’re testing things.
