12-inch 78 rpm record (1903 – mid 1950s)

12-inch 78 rpm records were introduced slightly later than the 10-inch version, becoming widely available in 1903.

They increased the playing time to 4 or 5 minutes per side, over the 10-inch version’s 3 minutes and just 2 minutes for contemporary cylinders.

Despite their longer playing time, there were fewer releases on the 12-inch size, and they appear to have died out in the mid-1950s.
