Wikipedia: Paper size
Many paper size standards conventions have existed at different times and in different countries. Today, the A and B series of ISO 216, which includes the commonly used A4 size, are the international standard used by almost every country. In many American countries as well as in the Philippines, ‘Letter’ is more prevalent. Paper sizes affect writing paper, stationery, cards, and some printed documents. The international standard for envelopes is the C series of ISO 269.

wonders - if you ask somebody to spend a lot of time looking for European-sized paper on your behalf, do you call that getting A4 effort?
