    The problem is that A4 is *NOT* exactly 210mm*297mm.
    (Further more, the 2.835016835017 is incorrect. You convert from mm to pps by dividing by 25.4 and multiplying by 72. Hence the ratio is 2.83464566929133858267).
    The code that I posted in may produces correct sizes.
    (Except for the "m65" format, sorry. "m65" is the same as "dl", and should return the same values).

    Try this...

    <?

    function mm2pt($val){
        return     floatval($val * 2.835016835017);
        }

    $xpdf = pdf_new();
    pdf_open_file($xpdf);
    pdf_begin_page($xpdf, mm2pt(210), mm2pt(297));

    // ...

    ?>

    I spent a lot of hours tweaking numbers in my PDF source, trying to nudge things the right way, and, invariably, really messing up big-time...

    Then one day I realized that all these numbers were supposed to be (INCHES * 72).

    Now my PDF code looks more like:
    <?php
    .
    .
    .
          pdf_begin_page($pdf, 8.5 * 72, 11 * 72);
    .
    .      /* set up $helvetica as font */
    .
          pdf_set_font($pdf, $helvetica, 9);
          $leading = pdf_get_value($pdf, 'leading');
          pdf_show_boxed($pdf, 0.5 * 72, 0.5 * 72, 4.0 * 72, $leading, 'left', '');
    ?>

    0.0, 0.0 is at the bottom left.
    8.5 * 72, 11 * 72 is at the top right.
    Everything in between is in x.xx * 72 where x.xx is INCHES.

    Suddenly, I can visualize the PDF while I'm typing.

    Might work for you too.

    The DIN paper sizes below are rounded.
    Theese functions returns exact paper sizes:

    <?php
    function paperheight($papername) {
          $name=strtolower($papername);
      switch(    $name) {
      case     "dl": return 11/2.54*72;
      case     "m65": return paperheight("c6");
      case     "ledger": case "tabloid": return  17*72;
      case     "legal": return paperwidth("ledger");
      case     "letter": return 11*72;
      default: return     paperwidth($name)*sqrt(2);
      }
    }
    function     paperwidth($papername) {
          $name=strtolower($papername);
      switch(    $name) {
      case     "dl": return 22/2.54*72;
      case     "m65": return paperwidth("c5");
      case     "ledger": case "tabloid": return  14*72;
      case     "legal": case "letter": return paperheight("ledger")>>1;
      default:
            $i=strpos("ebca",$name{0});
            $j=substr($name,1);
        if(    $i!=false && ($j>0 || $j==="0"))
          return     100/(pow(2,($i+$j*4-1)/8))/2.54*72;
        else
          die(    "Unkown paper format: $papername");
      }
    }

    $paper = "A4";
    $w = paperwidth($paper);
    $h = paperheight($paper);
    echo     "$paper: $w ppt * $h ppt";
    ?>
