Resolution Manager Script Unity3d

Hello developers,
As a mobile app/game developers it is not quite easy to make app/game UI same on different resolution devices,
In previous post you can see common resolutions with aspect ratios, also most used resolution devices among with that,
Below is the Unity3d Monobehaviour version of that discussion which is quite easy to get and use,

using UnityEngine;
using System.Collections;

public class ResolutionManager : MonoBehaviour 
{
public int bgWidthToLaod = 800;

float xWidth;
float yHeight;

void Awake()
{
xWidth = Screen.width;
yHeight = Screen.height;

float aspectRatio = xWidth / yHeight;

if(aspectRatio >= 1.30f && aspectRatio <= 1.35f)
{
// 2048 * 1536
aspectRatio = 1.33f;
bgWidthToLaod = 2048;
}
else if(aspectRatio >= 1.45f && aspectRatio <= 1.55f)
{
// 960 * 640
aspectRatio = 1.5f;
bgWidthToLaod = 960;
}
else if(aspectRatio >= 1.58f && aspectRatio <= 1.70f)
{
// 1280 * 768
aspectRatio = 1.67f;
bgWidthToLaod = 1280;
}
else if(aspectRatio >= 1.75f && aspectRatio <= 1.80f)
{
// 1136 * 640
aspectRatio = 1.78f;
bgWidthToLaod = 1136;
}
else
{
aspectRatio = 1.67f;
bgWidthToLaod = 1280;
}
}
}
