4A0 & 2A0 - The DIN 476 Oversize Formats

The paper sizes bigger than A0, 4A0 & 2A0, aren't formally divers past ISO 216 simply are commonly used for oversized paper.

A3+ (Super A3)

A3 Plus, or Super A3 as it is sometimes known, is not an ISO 216 paper size. It has dimensions of 330mm x 483mm (thirteen" x xix").

In actuality the A3+/Super A3 name is quite misleading every bit this paper size is known as B+ or Super B in the U.s. and is ANSI B with a 1" margin for impress drain.
