What should be the logo size for a Unity3D project?

Question

Unity

The question must seem silly, but still.
When you add your logo for a project in Unity3D, the logo is distorted, that is, it is either stretched, and so on.
Q: What should be the optimal image size?

Answer 1

Logo? are you talking about the SplashScreen field?
If about him, then there is a setting. stretch it. put in the center, etc.
The optimal size, but you are talking about the aspect ratio? there is no such thing as everyone has different screens. Choose the option that suits you to fill the splash screen with a texture and the resolution is not low)).
