What is the Scale Length of a guitar?

Scale Length is simply the length of the guitar, between Nut and Bridge.

Most modern Classical or Classic Guitars have a scale length of 650 mm, but this isn't fixed. The scale length can vary between mm for a Señorita guitar, right up to 664 mm for some of the larger Concert Guitars.

Each Guitar Orchestra Instrument has a different scale length.

Within the Niibori family, the most common scale lengths are :

Alto guitar : 535 mm

Bass guitar : 700 mm

Contrabass guitar : 750 mm
