How to get height and width of a pdf while using PDF BOX

Question

Here is a question: When I use PDF Box, I have no idea how to get height and width of a PDF file. I cannot see any method for get.

PDDocument pdDocument = getPDDocument(fis);
PDPage doc = pdDocument.getPage(0);

What is the "height" of a PDF file? Maybe you mean the height of a page in the PDF document? — Abra, Apr 18 '20 at 08:22
Unrelated - assuming that "fis" is a FileInputStream, you can get better performance by using a File directly. — Tilman Hausherr, Apr 18 '20 at 09:08

Inside of each PDPage you have a method called getMediaBox() that returns a PDRectangle. You can obtain the height and the width.

Be careful with the UOM that represent the width and height.

If you want the *visible* page size, you should use the **CropBox** instead. Read [this answer](https://stackoverflow.com/a/13240546/1729265) for an overview of the boxes defined for a page. And check the page **Rotate** value, if it's 90 or 270, you have to switch width and height. – mkl Apr 18 '20 at 10:43
