            address_name: /^\w?\s?[a-zA-Z]+(,?\s([a-zA-Z])*)*$/,            /*allows numbers space capital letters and other word characters*/
            suburb: /^\w?\s?[a-zA-Z]+(,?\s([a-zA-Z])*)*$/,          /*allows numbers space capital letters and other word characters*/
            phone: /^\d{10}$/,                                                      /*8 number phone number*/
            length: /^\d[0-9]$/,
            height: /^\d[0-9]$/,
        }
        var length = form.length.value;
        var height = form.height.value;
        var area = length*height;

        var elCount = form.elements.length;
        for(var i = 0; i<elCount; i++)
        {
            var field = form.elements[i];
            if(field.type == 'text')
            {
                if(!formats[field.name].test(field.value))
                {
                    alert('invalid '+ field.name.replace('_',' ')+'.');             /*alerts the name of the area not filled right in a pop up box*/
                    field.focus();
                    return false;
                }
            }
        }
        alert('All fields correct, the form will now submit.')
}

Why bother with all that? Just let users put in what they want. Your regular expression for name fields only allows one hyphen or space, address_number doesn't allow things like 2/34. The address_name doesn't allow numbers (e.g. 23rd st) or commas if there is more than just a street name, same for suburb, and phone numbers can be fewer than 10 characters (even though the comment says 8), and so on. — RobG

\d+ should be any digit, at least once, but like, however many as you'd like.

And \d[0-9] is redundant, just \d will suffice.

@Lazerblade Yup. That's why I left it out.
