I want the address fields to take up less space?

I want my form to sit on a single A4 page - please can you tell me how i can compact the address fields as i sometimes have two addresses (invoice and delivery) and they are taking up over half the page.

thank you

Please add the CSS code below:

.form-address-table{

  width: 300px;

}

Feel free to change the width as per your wish.
