Printing Lingo: What is -A-Series- Paper, such as A3, A4, A5, etc.?
In the United States, and other parts of North America,
standard paper sizes are based on inch measurements. For example, the three
most popular US paper sizes are 8.5" x 11" (Letter), 8.5" x 14" (Legal), and 11"
x 17" (Tabloid/Ledger).

A-Series refers to the most popular size category within the
International paper system. Paper sizes within the A-Series range from A0 (largest)
to A10 (smallest).
Looking at the size chart, you will notice that the A-Series follows a very logical sizing
system. It starts with the A0 sheet size, which has an area equal to one square
meter. Next is the A1 sheet size which is one-half the size of A0. The A2 size
is one-half the size of A1, the A3 size is one-half the size of A2 and so on.
Also, all A-Series sheets have a consistent size ratio, with
the longest side of a sheet being equal to the shortest side multiplied by the
square root of two (approximately 1.41).
In case you are wondering, the most common sheet size in the
world is A4, which measures 8.27" x 11.69" or 210mm x 297mm.
