Aspose-PDF Java- HTML to PDF

Hi,
I am converting an HTML file to PDF using aspose PDF.
I want to increase the page size to A2 and the contents of the HTML should also scale up accordingly. But this is not happening right now.
Following is the current code. Can you tell me the appropriate code changes.

HtmlLoadOptions options = new HtmlLoadOptions();

    // Initialize document object
    Document document = new Document(filePath, options);
    // Save output PDF document
    document.save(this.destinationFilePath);
