for orthographic camera, put this on your camera:

private float orthoSize, aspect;

void Start()
{
orthoSize = 5;// size of your camera in inspector
aspect =16/9; //your scene aspect ratio or target screen resolution = 1920/1080 , 1280/720, 4/3…

Camera.main.projectionMatrix = Matrix4x4.Ortho(-orthoSize * aspect, orthoSize * aspect, -orthoSize, orthoSize, Camera.main.nearClipPlane, Camera.main.farClipPlane);
}
