How can I check if there is no free space in the Text component?

In my canvas component I print text one symbol after another and I need to stop printing if text does not fit. After press next button other part of the text will be printed. But how can I check if there is no free space in the Text component? I don't need slider here. If all symbols are "i", then I can print 432 of it. And if "w" - then 126.

 private IEnumerator TextDelay()
 {
     isTextTyping = true;
     foreach (char i in
         contentToPrint.stringsToPrint[NumberOfStringToPrint])
     {
         if (i != ' ')
             audioTapText.Play();
         textComponent.text += i;
         yield return new WaitForSeconds(0.04f);
     }
     isTextTyping = false;
 }

And I don't want to print half of the word at the end. Then, after press next, print other half
