PDF_begin_page_ext
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);
It´s a small step i know... but it´s just the last mm.
