I have created a clone version of your form and added the CSS codes below to it.

.form-input-wide, .form-textbox, .form-address-table, .form-address-line, .form-checkbox-item, .form-radio-item, .form-textarea{

    max-width: 600px !important;

}

[id$="_phone"]{

max-width: 390px !important;

}

You can refer to this guide to learn how to inject custom CSS to your forms:

Here's the link to the clone version of your form that I have used for testing.
