Unusual size
* European shellac records — In the first three decades of the twentieth century European companies including Pathé, Odeon, and Fonotipia made recordings in a variety of sizes, including 21 cm, 25 cm, 27 cm, 29 cm, 35 cm, and 50 cm (roughly 8½", 10", 11¾", 12", 14", and 20").
* 16" and 20" discs — Broadcasting studios made use of 16" and 20" 78rpm acetate "transcriptions"; these were used for time-delay programs and for prerecorded broadcasts. These could provide up to 20 minutes of unbroken program material with very good fidelity (indistinguishable from live to casual, but not to critical listeners). Early classical LP recordings were in fact initially recorded on 20" 78-rpm acetates for later transfer to LP. 16" turntables are still seen in professional broadcast equipment, although it is probably very rare that any disk larger than 12" is ever played on them.
7" and 5" singles.
* 8" EPs. Mostly seen as Japanese pressed records in the 1980s and 1990s, and after 1992 in the US (one record plant started producing them after then).
* 7" 78-rpm children's records — The 78 rpm records of the 1920s, 1930s, and 1940s were breakable shellac (and broken records were a very common accident). In the 1950s, unbreakable records of various plastic compositions were introduced and coexisted with breakable shellac records. Unbreakable records were, of course, favored for children's records. A common format for children's records was the 7" 78-rpm unbreakable record, easily handled by small hands, and during the 1950s, 6" Little Golden Records made of bright yellow plastic were a common sight in children's playrooms in the United States. Earlier, non-children's 78s were 7 or 8 inches (from about 1900-1910s, Little Wonder Records being about 5 inches in diameter until 1923)
* 6", 7", 8", and 9" flexi discs were popular in Japan where they were known as sound-sheets and were often in traditional round format. In other areas, flexi disks were usually square and often included in a magazine. For example, the American magazine National Geographic's January 1979 issue included a flexi disk of whale sounds called "Songs of the Humpback Whale." With a production order of 10,500,000 copies, it became the largest single press run of any record at the time.
* 5", 6", 9", 11", and 13" records. In 1980, the British band Squeeze released a 5-inch 33⅓ RPM vinyl recording of "If I Didn't Love You", backed with "Another Nail In My Heart" (A&M Records AM-1616 / SP-4802). Due to space restrictions of the grooves, both songs were mixed as monaural. In the late `80's, Spirit released a 6-inch single, a re-recording of their late `60's hit, "Fresh Garbage", on Mercury Records. Underground hardcore punk bands in the 1990s started releasing EPs on all sizes of vinyl from 5" to 13" in size. UK Goth band Alien Sex Fiend were the first band to release an 11" record in October 1984. Popular industrial music group Nine Inch Nails has released a limited edition series of 9" discs, to aid in promoting the single March of the Pigs from their full length 1994 album The Downward Spiral. The record featured 2 songs on the first side, and an etching of the album's promotional logo (a coiled centipede) on the second side.
* 120 mm records. Techno artist Jeff Mills released the single for the Occurrence on a disc that is a gramophone record on one side, and a compact disc on the other. Although dubbed a 5" record, to be usable in most compact disc players, the record can be no bigger than 120 mm or about 4.7".[1]
* a 1" record was released by the hardcore band Spazz on Slap A Ham Records. It contains one track on each side : "Hemorrhoidal Dance of Death" (played at 78 RPM) and "Patches Are For Posers" (played at 33 RPM). The edition was limited to 14 copies. Similarly, Japanese grindcore band Slight Slappers released a 2" on the same label, limited to 666 copies.
* Oddly shaped discs were also produced (see shaped discs below).
