BASIC PRINCIPLES

1. FORMULA OF HALVING RANGES
   Each consecutive format evolves
   through doubling or halving the
   previous one.
   The areas of both formats relate as 1:2.
   �


2. FORMULA OF SIMILARITY IN RANGES
   The formats are similar to each other.
   Nos. 1 and 2 in the range give, for the two
   sides of x and y of one format. the propor­
   tions X:Y = 1 :-J2 �

Both sides are therefore in proportion to

each other as the sides of a square are to

its diagonal. �

3. FORMULA OF CONNECTED RANGES
   The formats are connected to the metric
   system: the area of the basic norm equals
   the area of a square metre, i.e. x X y = 1.
