``` 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.Sample linked from:http://l-i-e.com/resume.htm ```

``` 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:<?phpfunction 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";?> ```
