Walter Porstmann started with the largest sizes instead, assigning one an area of 1 m 2 (11 sq ft) (A0) and the other a short edge of 1 m (3 ft 3 in) (B0). He thereby turned the forgotten French sizes (relatively few in number) into a logically-simple and comprehensive plan for a full range of paper sizes, while introducing systematic ...

A0 is defined so that it has an area of 1 m 2 (11 sq ft) before rounding to the nearest 1 millimetre (0.039 in). Successive paper sizes in the series (A1, A2, A3, etc.) are defined by halving the area of the preceding paper size and rounding down, so that the long side of A( n + 1) is the same length as the short side of A n .

The main figure shows 4:3 and 2.40:1 rectangles with the same area A, and 16:9 rectangles that covers (black) or is common to (grey) them.The calculation considers the extreme rectangles, where m and n are multipliers to maintain their respective aspect ratios and areas.
The canvas exhibits a 0.1 strain in the weft direction and 0.2 strain in the warp direction before failing (thread ripping apart). [15] Though, tensile testing provides an explicit measure of material strength, conservators are unable to tare a piece of painting to create the samples (required length of 250 mm), therefore the traditional ...
