[RMVX ACE] [SCRIPTING] BALLOON DIALOG SIZE ADJUSTMENT

I was looking for a balloon message script, and I found this one that looks great and exactly what I needed:

But when if I change font size or font name, the balloon size won't adjust correspondingly. The script is huge, I have no idea where to change. Can anyone help?
