Relative widths of the acoustic guitar nuts
The picture above shows the relative sizes of the nuts. Use it for comparison only – the real size of the nut on your screen might be different due to the picture scaling on your computer.
A few extra comments
- When someone says wide neck acoustic guitar, he/she usually means a guitar with the neck wider than 1 3/4″.
- Usually, crossover guitars are nylon-string guitars with long neck connecting to the body at the 14th fret and with the neck width 1 7/8″
- A lot of custom guitars and many “build to order” (BTO) guitars might have a neck that is narrower or wider than one on the corresponding non-custom models.
