A5 Paper Size

Sure! It’s not an option by default because the template is not optimized for A5.
Check the documentation here: Custom page size/orientation

Ewout

I tried to follow “To use A5 for packing slip” code section in my functions.php page and removed the if block, but it still didn’t show A5 in settings ??

The code applies directly to the PDF, you don’t get an extra setting!

Thanks. I will try and let you know ??
