A US Letter PDF printed on A4 paper gets cut off at the bottom; an A4 document printed in the US gets cut at the sides. Resizing the pages to the paper the reader uses – or to one size for a mixed bundle of scans – fixes printing and makes a merged document look consistent.
A4 (210 × 297 mm) is the standard almost everywhere; US Letter (8.5 × 11 in, 216 × 279 mm) in the USA, Canada and parts of Latin America. Letter is wider and shorter, so a Letter page printed on A4 loses its bottom lines, and an A4 page printed on Letter loses its edges. Resizing scales the content so the whole page prints.
A contract drafted in the US arrives on Letter paper and must be printed and signed in Europe. Drop it and click A4: every page is scaled to fit A4 without cutting off the signature block at the bottom.
