Resize font of all texts to the same value

Question

I have some Text objects in UI. And I set Best Fit to true for all of them.the problem that I face,is that the length of their texts are variable,therefore their responsive font sizes are different from each other. I tried to write this script to change the font size of all texts to the smallest one but it wont work. How can I overcome this problem?

 public class FontResizer : MonoBehaviour {
 
     public Text[] txtBoxes;
     public float[] fontSizes;
     float min;
 
     void Start () {
         fontSizes = new float[txtBoxes.Length];
 
         for (int i = 0; i < fontSizes.Length; i++)
         {
             fontSizes[i] = txtBoxes[i].cachedTextGenerator.fontSizeUsedForBestFit;
         }
 
         min = 100000;
         for (int i = 0; i < fontSizes.Length; i++)
         {
             if (min > fontSizes[i])
             {
                 min = fontSizes[i];
             }
         }
 
         for (int i = 0; i < fontSizes.Length; i++)
         {
             txtBoxes[i].resizeTextForBestFit = false;
         }
 
         for (int i = 0; i < fontSizes.Length; i++)
         {
             txtBoxes[i].fontSize = Mathf.FloorToInt(min);
         }
 
 
     }
 }

You need to delay a single frame size the "best fit" size is still being determined in Frame 1. Therefore, putting the code in a coroutine will help. I also cleaned it up a little

     public Text[] txtBoxes;
 
     void Start () 
     {
         StartCoroutine (SetTextSize ());    
     }
         
     IEnumerator SetTextSize ()
     {
         //Need to delay a frame
         yield return null;
 
         int minSize = 1000;
 
         //Find smallest
         for (int i = 0; i < txtBoxes.Length; i++)
         {
             if (minSize > txtBoxes [i].cachedTextGenerator.fontSizeUsedForBestFit)
                 minSize = txtBoxes [i].cachedTextGenerator.fontSizeUsedForBestFit;
         }
 
         //Set smallest
         for (int i = 0; i < txtBoxes.Length; i++)
         {
             txtBoxes[i].resizeTextMaxSize = minSize;
         }
     }
