Please do yourself a favor and read the documentation!

As explained in the Getting started section, measurements are expressed in user units, and there are 72 user units in an inch, so:

8.5 inch x 72 points = 612 user units
12 inch x 72 points = 861 user units

So you need to create a rectangle like this:

Rectangle pagesize = new Rectangle(612, 861);

and a document like this:

Document document = new Document(pagesize);
