Responsive text size within fixed text box?

Hello all!

I am currently building a template with fixed frame size and text box size.
The question is, would it be possible to build a text box that will have the size of the text changes automatically depending on the amount of the text being input?

The goal is to keep the layout intact and let users to input variable length of text. (not without limit of course)

Thank you all for the advice and tips! :smiling_face:
