Abstract

We are all familiar with standard A4 and A3 sheets of paper. Most of us are also probably aware that an A3 sheet can be cut in half to form two A4 sheets. A standard A4 sheet of paper measures 210 mm by 297 mm while a standard A3 sheet of paper measures 297 mm by 420 mm. From these dimensions we can see that A4 and A3 sheets of paper are since the ratio of the longer side to the shorter side is the same in both cases, i.e. 1,414.
