Dearest #GlobalTalk and #MARCHintosh folk. Is it only the King's English countries that use A4 paper, or Southern Hemisphere, or something? Just so I know what paper size to use when I spam print anyone something.

@nygl A4 when I'm printing on paper, but when I'm cardmaking I use letter size cardstock.

That's because some of US & Canadian cardmakers I follow on Patreon will share PDFs of printables that can be used in cardmaking (backgrounds, focal images, patterned paper, sentiments, etc), and the PDF files they produce are designed to be printed on letter size.
