I want to print to A4 using css.
A4 is 297mm high - 6 mm margin top - 6 mm margin bottom = 285 mm should be left for content.
In IE 11 :
I have to set page borders to 6 mm and disable header/footer
--> Text appears where it should when I set content height to 284 mm (1 mm diff is close enough for me)

In Chrome 33:
I don't have to change any settings
--> Text is located far below from where it should be. It only works when I set content height to 267 mm (where did 18 mm diff go?)

<!DOCTYPE html>
<html>
   <head>
      <style type="text/css">
         @page {
            margin: 6mm;
            size: A4 portrait;
         }
         body {
            margin: 0mm;
         }
         table {
            page-break-after: always;
            border-spacing:0mm;
         }
         tr {
            vertical-align: bottom;
            height:284mm;
         }
      </style>
   </head>
   <body>
      <table>
         <tr>
            <td>Page 1</td>
         </tr>
      </table>
      <table>
         <tr>
            <td>Page 2</td>
         </tr>
     </table>
   </body>
</html>
Is there something wrong with my css or does Chrome not know the size of 1 mm?
