The Buffalo Convention of December 10, 1908 established two future roll formats for the US-producers of piano rolls for self-playing pianos. The two formats had different punchings of 65 and 88 notes, but the same width (11 1/4 inches or 285 mm). This made it possible to play the piano rolls on any self-playing instrument built according to the convention, albeit sometimes with a loss of special functionality. This format became a loose world standard.
