Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. </p> <p  style="margin-top:20px">Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.</p></div>');
       
html2pdf($Obj[0], {
    margin: 0,
    filename: 'sample.pdf',

Check out the link given below and set height accordingly to A4 size

$html2pdf = new HTML2PDF('P', array($width_in_mm,$height_in_mm), 'en', true, 'UTF-8', array(0, 0, 0, 0));

Width and Height should be in MM.

$width_in_mm = $width_in_inches * 25.4; 
$height_in_mm = $height_in_inches * 25.4;

HTML2PDF page size
