Canvas Scaler, Explained | Unity Tutorial

Learn all about the Canvas Scaler! The Canvas Scaler comes by default whenever you make a Canvas in Unity, but many of us don't fully understand how it works or what it does. When making a game, ensuring your UI scales reasonably across multiple different aspect ratios and screen resolutions is critical.

In this video we'll dive deep into each scale mode available in the Canvas Scaler:
⚫ Constant Pixel Size
⚫ Scale With Screen Size
⚫ Constant Physical Size
and talk about the strengths, weaknesses, and how to use each one.
