Acoustic Guitar Nut Width + Comparison Chart

In the following article, we’re going to discuss what nut width is on your acoustic guitar and how it affects playability. We’ve also included a handy comparison table showing the nut widths of some of the more popular acoustic guitars available today, so you can make a direct comparison.

🔑  Key Points:
Nut width refers to the width of the nut, which resides at the end of the fretboard nearest the headstock. Nut width dictates the string spacing at the open position on the fretboard (the first four frets) and affects playability with regard to the fretting hand.

What is Nut Width

Nut width is the term used to describe the width of the nut, the white plastic or bone component on your acoustic guitar that separates the fretboard from the headstock.

The nut is slotted at different depths to allow for the different string gauges in a set of guitar strings. The strings sit within these grooves and the distance between them dictates just how much string separation there is between the strings at the nut.

A wider nut offers more separation between the strings at the headstock end of the neck, while a narrower nut means the strings are closer together. This does not mean nut width dictates the string spacing of the guitar as a whole, as the neck tapers and the saddle is wider than the nut and therefore is spaced more widely at the saddle.

Is nut width the same as neck width?

Some incorrectly refer to nut width as neck width, but this is incorrect as neck width is a more general term that incorporates nut width, string spacing and fretboard width.

If you look down the neck of your guitar, you will notice the neck taper increases as you continue along the neck toward the higher frets, as a result nut width does not directly relate to neck width, although they are often used interchangeably.

Are nut width and string spacing the same thing?

No, nut width refers to the width of the nut only, string spacing refers to the distance between the strings. And, while a wider nut width often equates to a wider string spacing in the open position (the first four frets), specific nut widths don’t relate to specific string spacings. Both can vary, so the relationship between the two is more general in nature. It’s true that guitars with wider nut widths will often also have wider than average string spacings but there’s no defined standard.

Obviously string spacing at the headstock end of the guitar is determined by the nut width but the string spacing gets wider (typically about 10% wider) the further along the neck you go and the closer you measure in proximity to the saddle, as the saddle of the guitar is wider than the nut.

String spacing as a result is measured directly at the saddle, or in other instances, and for different manufacturers this measurement is taken at the 14th fret.

How is Nut Width Shown

Nut width is usually represented in inches, usually as a fractional measurement e.g. 1 3/4.

It is sometimes shown in decimals also e.g. 1.750 or millimeters e.g. 44.5mm (rounded up from 44.45mm)

Fractional Decimal MM
1 ¾ 1.750 45mm

 

Common nut widths on steel string acoustic guitars

There isn’t a standard nut width for steel string acoustic guitars. Manufacturers build guitars based on their own standards but an average nut width would be close to 1 11/16 or 43mm.

However, as you can see on the comparison chart below, nut widths vary across guitars, catering to a wide range of players with different preferences in this area.

The list below includes guitars of all price ranges, including the Martin D28 (RRP $3,599) through to the less expensive Epiphone DR100 (RRP $232). The different specificaitons have been listed as either fractional or decimal, depending on which makes mroe sense as a format for the given nut width.

Epiphone DR100 1.68″
Martin LX1 1 11/16″

Classical Guitar Nut WidthClassical Guitar Nut Width

As the table above indicates, nut width for steel string acoustic guitars can vary. However in the classical guitar world, the standard nut width which is 2″ or 51mm. This is changing however, as newer classical guitars from brandssuch as Cordoba, often referred to as crossover guitars, incoporate a narrower 1 7/8″ nut width.

How does nut width affect how the guitar plays?

Nut width is important, but is typically only considered by more experienced guitarists unfortunately.

If you are reasonably new to guitar and in the market for a new guitar, chances are you have preferences with regard to the brand, body shape, tonewoods, particularly the soundboard, perhaps the neck profile, and of course how the guitar sounds and plays.

Nut width also plays an important role with regard to playability but it gets less focus than it should, which is a shame because it has an immediate impact on the playability of the guitar, particularly for your fretting hand.

e.g. if you are anything like me with larger than average fingers a wider nut width is useful, as your hand will feel less cramped, allowing you to play more cleanly, especially in the open position as you are less likely to fret unwanted notes.

On the other hand many guitarists prefer a narrower nut width, especially those with a smaller hand span as it makes reaching the individual strings much easier. It really just comes down to personal preference, your physical limitations, and your approach to the guitar.

Do different genres matter?

It’s commonly thought that nut width is important with regard to your approach to the guitar e.g. do you play mostly with a pick or play fingerstyle. But for the most part nut width is less important than string spacing as nut width mostly affects the fretting hand and not the picking hand. However, the two are often mentioned within the same breath as typically a guitar with a wider nut width will also feature a wider string spacing. However the string spacing is not neccessarily just wider because the nut itself is wider.

Unlike string spacing which refers mostly influences the picking hand, nut width relates most strongly to the fretting hand and dictates the distance between the strings closer to the nut only.

Summary

Most guitarists over time will have a preference with regard to nut width, but there are other factors to consider if considering the playability of your acoustic guitar. This is why, If you are in the market for a new guitar, while it’s not always easy, it’s always best if you can test out the guitar by playing it before buying.

Nut width, string spacing, scale length and neck profile are always included in the specifications but how these relate to another, and ultimately how the guitar then feels to play can only really be experienced first-hand.
