This system of paper sizes is built on the following basis: each normal series (regularly derived sizes) consistsof a range of sizes formed in such a manner that each size is achieved by dividing the size immediately aboveit into two equal parts, the division being parallel to the shorter side (the halving principle).Consequently, theareas of two successive sizes are in the ratio 2:1(see Figure 1).
