Paper Size Differences: A4 vs US Letter
https://wiki-dale.win/index.php/Paper_Size_Differences:_A4_vs_US_Letter
A4 and US Letter are the two most common paper sizes, but their differences can trip you up. A4 is taller and narrower, measuring 210 x 297 mm, while US Letter is shorter and wider at 8.5 x 11 inches. This means documents designed for one often get cut off or misaligned on the other, especially with margins or images. If you're printing from a European template in the US, you might end up with unexpected white space or cropped text. It's worth checking your print settings before hitting go.
