I have already tried many scripts that looked the way I need it. However, none of them worked the way I needed it.

I have put together an inventory scene.
I started to create a 1920 x 1080 pixel image as the background.
I have created a scaling level x = 1.92, y = 1.08 and placed the background image on it.

It looks like this:

Then I applied the following script to the main camera to keep the aspect ratio at different screen sizes (seen from here) and make the background image completely visible:

using UnityEngine;

(RequireComponent(typeof(Camera)))
public class CameraCrop : MonoBehaviour {

    // Set this to your target aspect ratio, eg. (16, 9) or (4, 3).
    public Vector2 targetAspect = new Vector2(16, 9);
    Camera _camera;

    void Start () {
        _camera = GetComponent();
        UpdateCrop();
    }

    // Call this method if your window size or target aspect change.
    public void UpdateCrop() {
        // Determine ratios of screen/window & target, respectively.
        float screenRatio = Screen.width / (float)Screen.height;
        float targetRatio = targetAspect.x / targetAspect.y;

        if(Mathf.Approximately(screenRatio, targetRatio)) {
            // Screen or window is the target aspect ratio: use the whole area.
            _camera.rect = new Rect(0, 0, 1, 1);
        }
        else if(screenRatio > targetRatio) {
            // Screen or window is wider than the target: pillarbox.
            float normalizedWidth = targetRatio / screenRatio;
            float barThickness = (1f - normalizedWidth)/2f;
            _camera.rect = new Rect(barThickness, 0, normalizedWidth, 1);
        }
        else {
            // Screen or window is narrower than the target: letterbox.
            float normalizedHeight = screenRatio / targetRatio;
            float barThickness = (1f - normalizedHeight) / 2f;
            _camera.rect = new Rect(0, barThickness, 1, normalizedHeight);
        }
    }
}

However, this leads to the following gameplay:

Why is the script adding extra space at the top and bottom? That's a waste of space.

Many thanks.
