The 12-inch single is a type of gramophone record

 that has wider groove spacing compared to other types of records. This allows for louder levels to be cut on the disc by the cutting engineer, which in turn gives a wider dynamic range, and thus better sound quality. This record type is commonly used in disco and dance music genres, where DJs use them to play in discos or clubs. They are generally intended to be played at 45 rpm.

History

The 12-inch single gramophone record came into existence with the advent of disco music in the 1970s. The first 12" (30 cm) single was actually a 10" (25 cm) acetate used by a mix engineer

. As no 7" (18 cm) acetates could be found, a 10" (25 cm) blank was used. Moulton, feeling silly with a large disc which only had a couple of inches of groove on it, asked Rodriguez to re-cut it so that the grooves looked more spread out. Because of the wider spacing of the grooves, a broader overall dynamic range
Dynamic range

 (distinction between loud and soft) was made possible. This was immediately noticed to give a more favorable sound for discothèque play.

Moulton's position as the premiere mixer and "fix it man" for pop singles ensured that this fortunate accident would instantly become industry practice. This would perhaps have been a natural evolution: As songs became much longer than had been the average for a pop song

 wanted sufficient dynamic range, the format would have surely had to be changed from the 7 inch (18 cm) single eventually.

Also worth noting is that the visual spacing of the grooves on the 12" assisted the DJ in locating the approximate area of the "breaks" on the disc's surface (without having to listen as he dropped and re-dropped the stylus to find the right point). A quick study of any DJ's favorite discs will reveal mild wear in the "break points" on the discs surface that can clearly be seen by the naked eye, which further eases the "cueing" task (a club DJ's tone-arm cartridge will be heavily weighted and mild wear will seldom spoil the sound quality

). Many DJ-only remix services, such as Ultimix and Hot Tracks, issued sets with deliberately visualised groove separations (i.e., the record was cut with narrow and wider spacings that could be seen on the surface, marking the mix points on the often multi-song discs).

A broader dynamic range or louder recording level requires more space as the grooves' excursions (i.e., the width of the groove waves and distance traveled from side to side by the turntable stylus) become much greater in amplitude

The first very first 12" single was released in 1973 by soul/R&B musician/songwriter/producer Jerry Williams, Jr. aka Swamp Dogg. 12" promotional copies of "Straight From My Heart" were released on his own Swamp Dogg Presents label (Swamp Dogg Presents #501/SDP-SD01, 33⅓ r.p.m.) with distribution by Jamie/Guyden Distribution Corporation.

Increasingly in the 1980s, many pop and even rock artists released 12-inch singles that included longer, extended, or remixed versions of the actual track being promoted by the single. These versions were frequently labeled with the parenthetical designation "12-inch version", "12-inch mix", "extended remix", "dance mix", or "club mix".
