Inside of Form Builder for each text box field you can set Max Size of characters for that field.
I have made demo form with two fields. First field has Max Size of characters set to 5 and second field to 20 characters. Here is my demo form: http://form.jotformpro.com/form/52605695756972?
Hope this will help. Let us know if you need further assistance.
