How to size a Dynamic Text Box

How to size a Dynamic Text Box

Hello everyone,
I would like to know how it is possible to resize a Dynamic Text Box to be sure that my Limit text from my variable will be entered well inside ?
Is it possible to switch directly the variable in the Text Box to display the Limit Text ?
I don't know if it is clear ...
Thanks a lot !
