- A4 is 210 mm x 297 mm, making it longer and narrower.
- US Letter is 215.9 mm x 279.4 mm, making it wider and shorter.
- A4 is used internationally, while US Letter is standard in North and South America. Both work with most home and office printers.
- The difference may be minor, but it is important you set the paper size correctly in the printers settings and computers driver settings.
