The Baritone has a scale length of between 46 and 54 cm (18 - 21 inches) generally 50cm (20in). The Baritone was developed in the late 1920's or 1930's on the back of the fashion for multi-instruments, (like the Octaphone), however it wasn't called a Baritone until 1947 when both Vega and Favilla claimed to invent it. The Baritones usual tuning is not reentrant and is DGBE like a Guitars rather than the gCEA Ukulele standard, (Of course you can change this if you want but then its really a Jumbo Tenor). Anything bigger than a Baritone is not usually a Ukulele, more often than not its a Tenor Guitar, however there is a 21st century push on making Ukulele style instruments up to 66 cm (26in) scale with the wider Ukulele like neck, (at the moment this is more often referred to as "Long Scale" rather than "Bass Scale" but I have heard that too).
