Paper Size | WordPress.org

There’s a general guide here that you can use.

If this doesn’t work for you, could you share the error you’re receiving?

Excellent!, thank you very much, the snippet to convert to millimeters worked for me.

Now I just need to modify the margins, I found the “page class” in the CSS, but even though I modified it, it doesn’t seem to have an effect on the template

@page {
margin-top: 1cm;
margin-bottom: 3cm;
margin-left: 2cm;
margin-right: 2cm;
}

How should I modify them, is there a snippet for this as well?

You can try this snippet:

/**
 * Adjust margins
 */
/*add_action( 'wpo_wcpdf_custom_styles', function( $document_type, $document ) {
	?>
		@page {
			margin-top: 1cm;
			margin-bottom: 3cm;
			margin-left: 2cm;
			margin-right: 2cm;
		}
	<?php	
}, 10 , 2 );

Thanks, if it works, everything is fine now.
