If your child is about to start guitar lessons, you might wonder what the right guitar size for them is, given all the available options. This guide is designed to help you answer this question, with lots of other useful information to help you make the right buying decision. Read on!

What to look for when choosing a guitar

The right guitar must not be too big or too small for a child, must be comfortable to hold, and must allow the child to easily reach the top frets. If a child struggles to reach around the body of the guitar with one arm and/or can barely reach the frets with the other – you need a different guitar.

Ideally, you would be able to go to a physical store with your child and try out several different guitars before deciding on one. But if you are too busy to go guitar shopping, live too far away from a music store, or simply prefer to shop online – no problem! You can pretty reliably choose the correct guitar size for your child based on their age and a few other considerations that we talk about in this article.

Your Options

The four most popular options for child size guitars (from smallest to biggest) are the ukulele, guitalele, 1/2 size, and 3/4 size guitars. At around age 12, most children are grown enough to start using the full size guitar. Some manufacturers also offer a 1/4, 1/8  and 7/8 size guitars, but there are not very common and the sizes described here are entirely suitable and even preferable alternatives.

Having said that – let’s take a closer look at our options.

Now, let’s talk about each instrument in a bit more detail.


Age group: ≈ 2-5

Although technically not a guitar, the ukulele can be a great starter instrument for little kids. Children as young as 2 can start plucking away at the strings and experiment with the different sounds they make. It is small, light-weight, and uses nylon strings, which are easy on the fingers.

An important distinctive feature of the ukulele is that it has 4 strings as opposed to the standard 6 of the guitalele or other guitars. This definitely makes it easier for kids to play, but those who plan to move on to a guitar will eventually have to make the transition to 6 strings.

There are 4 main types of ukuleles: soprano, concert, tenor and baritone. Each one is slightly bigger and has a slightly different sound. The one we discuss here (see photo above) is a soprano ukulele, which is by far the most popular type and is what is considered a “standard” ukulele.

In addition to being a neat starter instrument for kids, the ukulele is also an instrument in its own right. Plenty of adults play the ukulele instead of guitar and really enjoy its compact size and distinctive sound.

Age group: ≈ 3-5
a guitalele

Another great option for little kids is the guitalele, which is ideal for 3 to 5 year-olds. The manufacturer Yamaha, who first introduced this instrument, describes it as “Half guitar, half ukulele…100% fun!”

As the name suggests, the guitalele is a sort of hybrid between the guitar and the ukulele. It is closer to the ukulele in the way it sounds and closer to a guitar in its more mature shape and its number of strings (6). Also like the ukulele, it uses nylon strings.

Although it resembles a guitar – it is actually tuned differently than a guitar – a 4th up. So, from bottom to top, the guitalele’s strings are A-D-G-C-E-A as opposed to the guitar’s E-A-D-G-B-E. This means that the chord shapes on a guitalele won’t give you the same chords as on the guitar. Despite this, it will get your child accustomed to 6 strings.

Some people prefer the guitalele to the ukulele precisely because it has the standard 6 strings of a regular guitar, which makes a later transition to a guitar easier a bit easier.

A solid and reliable choice:

1/2 (half-size) Guitar

Age group: ≈ 5-8
half size guitar
1/2 size Denver nylon-string classical guitar

Half size guitars are aimed at 5 to 8 year-olds, which makes them quite popular since many children start taking guitar lessons at this age.

1/2 size guitars are tuned just like real guitars, so children get a genuine guitar experience with this instrument.

They come in classical (nylon strings) and acoustic (steel strings) versions, though the nylon-string versions are recommended and preferred by most for learning as they are easier on the fingers.

Some electric versions of the 1/2 guitar also exist on the market, though most teachers would not recommend an electric guitar at this stage (unless your child is absolutely set on one!).

Thinking of buying a 1/2 guitar? Here are our recommendations based on our students’ experience and feedback:

A cheap, beginner option (30″):

3/4 (three-quarter size) Guitar

Age group: ≈ 8-12

3/4 size Denver steel-string acoustic guitar

The 3/4 size guitar is another very popular guitar size for young children and is best suited for 8 to 12 year-olds. As with the 1/2 size guitar, it also comes in classical, acoustic, and electric versions.

The 3/4 guitar has standard guitar tuning (E-A-D-G-B-E) and, at 36″ inches, is very close in size and feel to the full size guitar.

Although the classical (nylon strings) version is still the preferred choice for most, some students at this stage will already begin using acoustic versions (steel strings) to start preparing their fingers for the real, full size acoustic guitar.

Because of its slightly smaller size, some adults actually prefer to play the 3/4 size guitar as opposed to a full size one. In fact, the famous singer/songwriter Ed Sheeran is known to prefer 3/4 size guitars.

Thinking of buying a 3/4 size guitar? Here are our recommendations based on our students’ experience and feedback:

More expensive option:

Full Size Guitar

Age group: ≈ 12+

When we hear the word “guitar”, we usually mean a full size guitar. This is the famous instrument that many of your favourite bands and artists use and the one we usually hear on the radio or on recordings.

There are numerous brands and varieties of acoustic, classical, and electric full size guitars to choose from, so you are sure to find something that appeals to your taste.

Except for classical versions, full size guitars mostly come with steel strings.

Thinking of buying a full size guitar? Here are our recommendations based on our students’ experience and feedback:

For classical (nylon strings) full size guitars:

More pricey but reliable option:

For acoustic (steel strings) full size guitar:

For electric full size guitar:
