Short version: for an existing PDF use a PdfReader and read the page box (MediaBox/CropBox) — that gives a Rectangle you can query for width/height. ’s pointer to standard PageSize constants is useful when creating new pages, but to get the actual size of an existing file you must read the page dictionary at runtime (MediaBox/CropBox and rotation). (javadoc.io)

Example (iText 5, Java):

PdfReader reader = new PdfReader("input.pdf");
Rectangle r = reader.getPageSizeWithRotation(1); // takes rotation into account
float widthPts  = r.getWidth();
float heightPts = r.getHeight();
reader.close();

Those values are in PDF user units (points): 72 points = 1 inch, convert as mm = pts * 25.4f / 72f. The Rectangle class exposes getWidth()/getHeight(), getLeft()/getRight()/getTop()/getBottom() if you need coordinates. (api.itextpdf.com)

Notes/troubleshooting: getPageSize(int) returns the MediaBox without rotation; use getPageSizeWithRotation() or check getPageRotation() for orientation. If the visible page differs from MediaBox check getCropBox() or getBoxSize(...) (crop/trim/art/bleed/media). These differences are the common cause of “wrong” dimensions. (javadoc.io)

Placing a table at the bottom: build and lock the table width, compute table.getTotalHeight(), then write it absolutely with writeSelectedRows(...) onto the writer’s direct content. Y coordinate math matters — to place inside the bottom margin use document.bottom() + table.getTotalHeight(); to place exactly in the margin use document.bottom() (or adjust as needed). (api.itextpdf.com)

Tying back: ’s advice to read the docs is right — the javadocs/Kb pages above show the exact methods to use.
