297 mm
(11.69 inches)


ISO papers such as A3 paper, A4 paper, and A5

210 mm (8.27 inches)

paper are readily available internationally, however,
they are less easily found in the United States, Canada, Mexico, and the Philippines.  This situation may continue until business globalization in these areas reaches critical mass and demand for A4 paper and other ISO sizes is much greater.

Availability in the United States

Name-brand manufacturers such as Hewlett Packard provide the A4 paper size across a selection of inkjet paper, laser paper, and color laser paper products, but these are primarily marketed overseas, which makes it difficult to procure these name-brand products in the U.S. without additional shipping expense.

The A4 paper size and other general-purpose ISO paper sizes, such as A3 and A5, are hard-to-find sizes in the United States (i.e. not typically available in local office supply stores).  These paper sizes are included in the papers we specialize in for the U.S. market.
