Describe the bug
I'm using wkhtmltopdf and the output PDF is not 8.5x11. Any ideas how to change that now, or can it be something in the user-edited styles to be added? Before we switched to wkhtmltopdf the document size was 8.5x11.

Steps To Reproduce
Steps to reproduce the behavior:

Export document with wkhtmltopdf

Expected behavior
document size 8.5x11

Screenshots

Your Configuration (please complete the following information):

Exact BookStack Version (Found in settings): v0.22.0
PHP Version: 7
Hosting Method (Nginx/Apache/Docker): Nginx

Thanks to SwiftOtter we got it solved VIA the following:

"...we found that we can pass the page-size parameter to wkhtmltopdf through the config/snappy.php settings file"

Hope that helps others!

Hi @nvnvnvnvn,
I realise this is 3+ years late any may not even be relevant for you anymore, but I've wrapped this up into an .env option:

EXPORT_PAGE_SIZE=a4
# or
EXPORT_PAGE_SIZE=letter

Will be part of the next patch release.
