How do I get the width and height of a doc generated with FPDF

Question

How can I get height and width of a document in FPDF.

For example, I've next line:

$this->Cell(200,5,'ATHLETIC DE COLOMBIA S.A.',1,1,'C',1);

But, I want to do something like:

// $x = width of page
$this->Cell($x,5,'ATHLETIC DE COLOMBIA S.A.',1,1,'C',1);

Needed to do this myself so was just checking the most recent version of FPDF and it looks like the width & height are already available as public properties. So for anyone looking for the same info:

$pdf = new FPDF(); 
$pdf->addPage("P", "A4");

$pdf -> w; // Width of Current Page
$pdf -> h; // Height of Current Page

$pdf -> Line(0, 0, $pdf -> w, $pdf -> h);
$pdf -> Line($pdf -> w, 0, 0, $pdf -> h);

$pdf->Output('mypdf.pdf', 'I');

This is the correct answer, although this isn't on the documentation page. – Michael Greisman Jan 13 '14 at 16:43
You have to change publicity to public in current FPDF version. – Alexander G. Mar 08 '16 at 07:36

Nowadasy, you can simply call GetPageWidth and GetPageHeight methods.

$pdf = new FPDF(); 
$pdf->addPage("P", "A4");

$pdf->GetPageWidth();  // Width of Current Page
$pdf->GetPageHeight(); // Height of Current Page

What measurement is returned from `GetPageWidth`? pixels? mm? cm? – Broshi Jan 23 '18 at 20:08
mm, cm, pt or inches. By default it's mm. You can change it specifying another measurement at the creation of `FPDF`. – Ilario Pierbattista Jan 24 '18 at 07:49

Encase someone needs to get the width taking margins into consideration...

class FPDF_EXTEND extends FPDF
{

    public function pageWidth()
    {
        $width = $this->w;
        $leftMargin = $this->lMargin;
        $rightMargin = $this->rMargin;
        return $width-$rightMargin-$leftMargin;
    }

}

note: read Ross' McLellan's answer below

As far as I remember you can't do it with vanilla FPDF. You can either extend it to have a method that would return this value for you, or just store the width as a public property of fpdf object.
