Here’s one more look at the question of the diameter of vinyl records. While 7 and 12 inches remain the most common sizes, labels and artists love to experiment with different diameters. The 10-inch 78 remained in production until sometime in the early 60s. With the advent of disco, the 12-inch single appeared in the 1970s, spinning at 33 1/3 or 45 RPM depending on the release. Japan fooled about with 8-inch records–mostly EPs–in the 80s and 90s–as well as 6, 7, 8 and 9-inch flexi discs.
Not to be outdone, the British tried with 5, 6, 9, 11 and 13-inch records. Individual bands (Squeeze, Alien Sex Fiend, Nine Inch Nails and a variety of punk groups) had fun with special odd-sized releases (I have some 9-inch Nine Inch Nails vinyl. Nine inches. Geddit?) One of my favourites was “The Occurrence” from techno artist Jeff Mills, which was a standard CD on one side and a playable grooved record on the other, so it was five inches in diameter. And let’s not even start with what Jack White is doing with Third Man Records. That’s a whole ‘nother story.
