A custom pagesize

import java.io.FileOutputStream;
import com.lowagie.text.Document;
import com.lowagie.text.Paragraph;
import com.lowagie.text.Rectangle;
import com.lowagie.text.pdf.PdfWriter;
public class MainClass {
  public static void main(String[] args) throws Exception {
    Rectangle pageSize = new Rectangle(216f, 720f);
    Document document = new Document(pageSize);
    PdfWriter.getInstance(document,
        new FileOutputStream("HelloWorldNarrow.pdf"));
    document.open();
    document.add(new Paragraph("Hello World"));
    document.close();
  }
}

PageSize.LETTER

import java.io.FileOutputStream;
import com.lowagie.text.Document;
import com.lowagie.text.PageSize;
import com.lowagie.text.Paragraph;
import com.lowagie.text.pdf.PdfWriter;
public class MainClass {
  public static void main(String[] args) throws Exception {
    Document document = new Document(PageSize.LETTER);
    PdfWriter.getInstance(document,
        new FileOutputStream("HelloWorldLetter.pdf"));
    document.open();
    document.add(new Paragraph("Hello World"));
    document.close();
  }
}

PageSize.LETTER.rotate()

import java.io.FileOutputStream;
import com.lowagie.text.Document;
import com.lowagie.text.PageSize;
import com.lowagie.text.Paragraph;
import com.lowagie.text.pdf.PdfWriter;
public class MainClass {
  public static void main(String[] args) throws Exception {
    Document document = new Document(PageSize.LETTER.rotate());
    PdfWriter.getInstance(document, new FileOutputStream("1.pdf"));
    document.open();
    document.add(new Paragraph("Hello World"));
    document.close();
  }
}

Set page size to LETTER, the orientation to Landscape

import java.io.FileOutputStream;
import com.lowagie.text.Document;
import com.lowagie.text.Paragraph;
import com.lowagie.text.Rectangle;
import com.lowagie.text.pdf.PdfWriter;
public class MainClass {
  public static void main(String[] args) throws Exception {
    Document document = new Document(new Rectangle(792, 612));
    PdfWriter.getInstance(document, new FileOutputStream("1.pdf"));
    document.open();
    document.add(new Paragraph("Hello World"));
    document.close();
  }
}

Some information on the page size

import com.lowagie.text.pdf.PdfReader;
public class MainClass {
  public static void main(String[] args) throws Exception {
    PdfReader reader = new PdfReader("HelloWorldToRead.pdf");
    System.out.println("Page size p1: " + reader.getPageSize(1));
    System.out.println("Rotation p1: " + reader.getPageRotation(1));
    System.out.println("Page size p3: " + reader.getPageSize(3));
    System.out.println("Rotation p3: " + reader.getPageRotation(3));
    System.out.println("Size with rotation p3: " + reader.getPageSizeWithRotation(3));
  }
}
