How to get the camera's size in world units

Hello, I have a scripting problem I’m trying to get past. So, I want my camera in my 2D game to follow the player until he/she reaches the set right and left ends of the map, but I can’t figure out how to get the proper property to do this. Here’s the code I’m using:

// constant “RightWorldBoundary” = 35f;
if (transform.position.x - camera._______ / 2 > Level.RightWorldBoundary)
{
return Level.RightWorldBoundary - camera._______ / 2;
}
// constant “LeftWorldBoundary” = -35f;
else if (transform.position.x + camera._______ / 2 < Level.LeftWorldBoundary)
{
return Level.LeftWorldBoundary + camera._______ / 2;
}

As another potentially useful note, I’m using a 16:9 ratio currently and I have a camera size of 10. What should I use in the ______ space to get the width of the camera in world units and have the same type of measurement as my other factors like the transform.position?

Okay, I’ve got it now. So, the “Size” property of the camera represents half of the camera’s height in world units. this is accessed by using
camera.orthographicSize
the height is already halved for you, so that’s not something you need to do. to convert from half the height to half the width, you just need to multiply camera.orthographicSize by camera.aspect, as I’ve done here:

        camera = UnityEngine.Camera.main;
        halfViewport = (camera.orthographicSize * camera.aspect);

here are the following edits I’ve made to my code with this in mind:

    private float WorldBourdaryReached()
    {
        float playerXPosition = player.transform.position.x;
        Debug.Log(playerXPosition);
        if (playerXPosition + halfViewport >= Level.RightWorldBoundary)
        {
            return Level.RightWorldBoundary - halfViewport;
        }
        else if (playerXPosition - halfViewport <= Level.LeftWorldBoundary)
        {
            return Level.LeftWorldBoundary + halfViewport;
        }
        else
            return 0f;
    }

In my main update method, if the return of this is 0 (the last statement), I’ll just use the player’s x position as the camera’s x, but if the return is anything but 0 (which will be the maximum the camera can move in either direction), I set the camera’s x to the return value.

// constant “RightWorldBoundary” = 35f;
if (transform.position.x - camera._______ / 2 > Level.RightWorldBoundary)
{
return Level.RightWorldBoundary - camera._______ / 2;
}
// constant “LeftWorldBoundary” = -35f;
else if (transform.position.x + camera._______ / 2 < Level.LeftWorldBoundary)
{
return Level.LeftWorldBoundary + camera._______ / 2;
}

Here’s a clearer view of my code (hopfully! I’m kina new to this).
