How to get exact text width from horizontal overflow: wrap?

In Unity, I tried to get a size of text component, not TMP, which has horizontal overflow: wrap and vertical overflow: overflow.

When the text amount was out off the rect width and a new line is added, text.preferredHeight works properly. It returns the lined height.

But text.preferredWidth returns a wrong value. It wroks like the horizontal overflow is just overflow, no matter what it is indeed.

I want to get a value that the wrapped lines are applied.

chat.text = 'looooooooooooooooooooooong word'; //text is wrapped. Extra line is created
Debug.Log(chat.perferredWidth); // returns wrong value. Extra line is not applied
Debug.Log(chat.perferredHeight); // returns correct value.

Actually text.preferredHeight will also give you a bigger value when some lines are truncated, you need to perform a simple comparison with the size of the rect transform:

public static class UGUIExtension
{
    public static float GetRenderWidth(this Text text)
        => text.horizontalOverflow == HorizontalWrapMode.Wrap ? 
           Mathf.Min(text.rectTransform.sizeDelta.x, text.preferredWidth) :
           text.preferredWidth;

    public static float GetRenderHeight(this Text text)
        => text.verticalOverflow == VerticalWrapMode.Truncate ?
           Mathf.Min(text.rectTransform.sizeDelta.y, text.preferredHeight) :
           text.preferredHeight;
}
