How to change the width of the form

Hello @ddangerfield

The form’s width is expanded to its container. If you insert a the form into a DIV tag with 500px of width, the form’s width would be 500px. If it is inserted into a DIV with 700px of width, the form’s width would be 700px too, and so on.

Another alternative, would be adjust the form’s width by itself. Through the shortcode it is possible assign a class name to the form, using the class attribute. For example:
[CP_CALCULATED_FIELDS id="1" class="my-class-name"]

and then, you can define the new class name, similar to:

.my-class-name{max-width:500px;}

Best regards.
