A 1 9/16 inch nut width guitar refers to the width of the nut, which is the piece of material at the base of the guitar’s fingerboard where the strings pass over.
This measurement is typically taken at the widest point of the nut and is an important factor in determining the feel and playability of a guitar.
A nut width of 1 9/16 inches is considered to be on the wider side and is typically found on acoustic guitars, particularly those with a dreadnought body shape.
Guitars with a wider nut width can make it easier for players with larger hands to play, as there is more space between the strings.
However, it can also make it more difficult for players with smaller hands to form chords and play certain techniques.
Also, note that different guitar makers and models may have slightly different measurements for nut widths. It’s always recommended to try out different guitars to find the one that feels most comfortable for you.
