How to fix sprite scaling in Unity?

Question

Unity

How to render sprites for different screens? With the button, I understand. There are anchors. How about a sprite? In the project, the picture is of normal size, and after assembly on Android, it goes beyond the screen.
And the buttons themselves on different screens are sometimes closer to oval, sometimes small.

Answer 1

It's not about sprites.
For the UI (if it is a standard unit one), the CanvasScaler component is hung up, which properly scales the UI.
For ingame, the main camera is resized. It is decided what is more important for the game - to align in height or in width. Initially - the alignment goes along the height.
