Ukuleles come in four different sizes, and the tenor ukulele is the third largest. For the most part, tenor ukuleles are very suitable for beginners. This is because the scale length, where the strings run across, is large. Therefore, the metal bars on a fretboard are more spread apart which makes it easier to pluck and make music. While smaller fingers can better navigate a tighter space, adults, especially those with larger fingers, will find it reassuring to have a bit more space when navigating the ukulele strings.
