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));

// ...

?>

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";
?>

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.

Points for CD covers (approximate values)

Front cover           (119x119mm)   => 337.33x337.33 points
Inlay including sides (150x117mm)   => 425.21x331.66 points
Inlay excluding sides (137.4x117mm) => 389.49x331.66 points

When you use the mentioned size of an a4 pdf file it will make a pdf file in the this size: 209.9 x 297 mm. If you want to create a real a4 sized pdf you can use the following:

PDF_begin_page($pdf, 595.3, 842);

Its a small step i know... but its just the last mm.
