Standard paper sizes and their U.S. and
ISO (International Organization for Standardization) conversions
Crafting has gone global. Great craft ideas and materials
come from all around the world now. Have you ever wondered
what A4 paper is? Fret no more. Here are some handy
conversion charts to help you figure out standard international paper
sizes.

In addition to the standard "A" sizes in ISO measurement, there are "B"
and "C" sizes as well. which were developed for different applications.
"C" sizes, for example, were developed for envelopes.
An unfolded A4 letter fits in a C4 envelope.
Folded once to an A5 size, it fits in a C5 envelope, and
folded twice, it fits in a C6 envelope. Don't you love
metrics?
Origami fans take note; the Japanese standards are slightly
different, so be aware when reading instructions.
