A non-standard F4 paper size is common in Southeast Asia. It is a transitional size with the shorter side of ISO A4 (210 mm, 8 + 1 ⁄ 4 inch) and the longer side of British Foolscap (13-inch (330 mm). ISO A4 is exactly 90% the height of F4. This size is sometimes also known as (metric) 'foolscap' or 'folio'.
At the time, the F-4 Phantom was just beginning to be exploited to its full potential as a fighter and had not performed as well as expected against the smaller North Vietnamese MiG-17 and MiG-21 opponents.

F4 [15] is a paper size 210 mm × 330 mm (8.27 in × 13.0 in). [16] Although metric, based on the A4 paper size, and named to suggest that it is part of the official ISO 216 paper sizes, it is only a de facto standard.
The last U.S.-built F-4 went to South Korea, while the last F-4 built was an F-4EJ built by Mitsubishi Heavy Industries in Japan and delivered on 20 May 1981.

Among fixed-wing aircraft, more F-4 Phantoms were lost than any other type in service with any nation. The United States lost 578 Ryan Model 147 Unmanned aerial vehicles (UAVs) (554 over Vietnam and 24 over China). [1] More than 400 QH-50C/D UAVs were also lost. [2] There were about 11,846 U.S helicopters that served in the Vietnam War.
The standard defines the "A", "B" and "C" series of paper sizes, which includes the A4, the most commonly available paper size worldwide. Two supplementary standards, ISO 217 and ISO 269 , define related paper sizes; the ISO 269 " C " series is commonly listed alongside the A and B sizes.
