How to limit the character count of a variable of a Catalog Item?

[Navya43]

I have a variable 'Comments' in a catalog item. But I want to limit the characters a user can input.

How can I achieve it? 'Comments' is already a Single Text Line type, but I need to limit the characters further more.

Please help!
