MemoryStream asposePdfXmlStream = null;
byte[] pdfBytes = null;
// First we need to convert word processing data into PDF xml format
convertFromDataStream = new MemoryStream(convertFromData);
asposePdfXmlStream = new MemoryStream();
wordDocument = new Document(convertFromDataStream);
wordDocument.Save(asposePdfXmlStream, saveFormat: SaveFormat.Pdf);
asposePdfXmlStream.Seek(0, SeekOrigin.Begin);
pdfBytes = asposePdfXmlStream.ToArray();

Hi Siva,
Aspose.Words for .NET renders the same page size as in the input document; if source document has ‘legal’ page size then output PDF will have the same size. I tested your code and it produces the same result.
If you want to change the page size or other properties, you can use PageSetup class for that purpose as you can see in the following code.

wordDocument = new Document(convertFromDataStream);
DocumentBuilder wordDocumentBuilder = new DocumentBuilder(wordDocument);
PageSetup pageSetup = wordDocumentBuilder.PageSetup;
pageSetup.PaperSize = PaperSize.Legal;
