Why Does Unity Resolution Not Change Anythings Size?

Notice how the Gengar does not change size at all, Nor does the UI size. The only thing that changes is the window size in windowed mode and the pixel resolution rendering size of UI elements such as text in fullscreen mode.

I have two questions.

  1. Why does it not change the size of any element in-game to help suit the size of the window?
  2. Why is it unaffected to change in fullscreen?

I tried doing research on Resolution which all I could find was SetResolution which does nothing but change the window size in windowed mode.

It’s likely due to your CanvasScaler settings (Redirect to... title of new-page). Try changing the UI Scale Mode to “Scale with Screen Size”.
