There are many ways to measure the guitars. Normally, the full size of a classic guitar is 39”; the full size of an acoustic guitar is 41”. How can we classify the guitars in 39” or 41”? For a classic guitar, you can measure it from the top of the headstock to the bottom of the body, then you will get the size 39”. For an acoustic guitar, the same way, then you will get the size 41”.
The overall length of the guitar is a good indicator of whether it is the correct size for the student. The only way to know the true size of a guitar is to measure its “scale length”. The scale length of a guitar is the length from the “bridge” of the guitar to the “nut” of the guitar. See the example below
As you can see from the picture above, the scale length measures the part of the strings that actually vibrate when you pluck the string. This is the only relevant way to compare guitar sizes. A 39″ classical guitar and a 41″ steel string guitar can have the exact same “scale length” and both of them can be “full size” guitars. The only way to be certain what size they are is to measure the scale length.

Guitar Type Size Chart - (common overall lengths)
| Classical(nylon string) | Acoustic(steel string) | Electric Guitar |
4/4 full size | 39”-40” | 40”-42” | 38”-40” |
3/4 size | 36” | 38” | 34”-36” |
1/2 size | 33” | 36” | 33” |
1/4 size | 31” | 32” | 31” |
The overall length of the guitar can vary widely depending on the style and overall design of the guitar.
Choosing the right size guitar to use depends on the arm’s reaching of your child. You can use age to determine the approximate guitar size for your child using the following chart
Age | Height of Player | Size of Guitar |
4-6 years old | 3′3″ to 3′9″ | 1/4 size |
5-8 years old | 3′10″ to 4′5″ | 1/2 size |
8-11 years old | 4′6″ to 4′11″ | 3/4 size |
11-Adult | 5′ or taller | 4/4 size |

In this way, your guitar becomes more than just a tool; it becomes a musical partner that can help you create a lifetime of your music.
