How Long Is A Guitar: Sizes, Types, And More
A full-size guitar is usually 38 to 42 inches long, while smaller guitars can measure 30 to 36 inches.
If you are asking how long is a guitar, the answer depends on its type, body shape, and size. An acoustic guitar, electric guitar, classical guitar, and child-size guitar can all have different measurements. Knowing the difference between total length and scale length will help you choose the right instrument, case, stand, or storage space.
How Long Is a Guitar?
Most full-size guitars measure about 38 to 42 inches from the top of the headstock to the bottom of the body. This measurement is called the guitar’s total length.
Here are common ranges:
• Full-size acoustic guitar: 38 to 42 inches
• Full-size electric guitar: 38 to 41 inches
• Classical guitar: 38 to 40 inches
• Three-quarter guitar: 34 to 36 inches
• Half-size guitar: 30 to 34 inches
• Full-size bass guitar: 42 to 48 inches
These ranges are general. The exact length changes with the guitar’s body shape, headstock design, bridge position, and manufacturer. A dreadnought acoustic guitar, for example, often looks longer and larger than a concert-style acoustic guitar.
Total Guitar Length vs. Scale Length
When people ask how long is a guitar, they often mean total length. However, guitar makers and players also use the term scale length.
Total length is the distance from the end of the headstock to the bottom edge of the guitar body. It tells you how much space the entire instrument needs.
Scale length is the distance from the nut to the bridge saddle. It shows the length of the strings that vibrate. Scale length affects the guitar’s feel, tone, and string tension.
For example, two guitars may both measure 40 inches long but have different scale lengths. One may feel tighter and more spread out, while the other may feel softer and easier to play.
Common scale lengths include:
• Classical guitar: about 25.5 inches
• Steel-string acoustic guitar: about 24.75 to 25.5 inches
• Electric guitar: about 24 to 25.5 inches
• Short-scale electric guitar: about 24 inches
• Bass guitar: about 30 to 35 inches
A longer scale length usually creates more string tension when using the same strings and tuning. A shorter scale length can feel easier for beginners and players with smaller hands.
How Long Is an Acoustic Guitar?
A full-size acoustic guitar usually measures 38 to 42 inches long. Its body length often falls between 19 and 21 inches, while the neck and headstock make up the rest.
The shape of the acoustic guitar has a major effect on its size. A large dreadnought often measures close to 41 or 42 inches. A smaller parlor or concert guitar may measure around 38 to 40 inches.
Common acoustic guitar sizes include:
• Dreadnought: about 40 to 42 inches
• Jumbo: about 40 to 42 inches
• Grand auditorium: about 39 to 41 inches
• Concert guitar: about 38 to 40 inches
• Parlor guitar: about 38 to 40 inches
The total length does not tell the whole story. A jumbo guitar may not be much longer than a concert guitar, but it can be much wider and deeper. This matters when you are choosing a case or deciding whether the instrument will fit in a small room.
In my experience, players often measure only the neck and body length. That mistake can lead to buying a case that is too short. Always measure from the highest point of the headstock to the lowest point of the body.
How Long Is an Electric Guitar?
Most full-size electric guitars measure 38 to 41 inches long. They are often similar in total length to acoustic guitars, even though their bodies may be thinner and smaller.
An electric guitar can seem shorter because its body is usually slim. Its neck may also look longer in relation to the body. Still, the headstock adds several inches to the overall length.
Typical examples include:
• Solid-body electric guitar: about 38 to 40 inches
• Offset electric guitar: about 39 to 41 inches
• Short-scale electric guitar: about 35 to 38 inches
• Hollow-body electric guitar: about 40 to 42 inches
A guitar with a longer headstock may have the same scale length as another guitar but a greater total length. This is why you should check the complete manufacturer measurements before buying a gig bag.
Electric guitar body width also matters. Most solid-body models are about 12 to 14 inches wide. Hollow-body models may be 15 to 17 inches wide, which can make them harder to store even if their total length is similar.
How Long Is a Classical Guitar?
A full-size classical guitar usually measures 38 to 40 inches long. Most classical guitars use nylon strings and have a wider neck than steel-string acoustic guitars.
The most common full-size classical guitar has a scale length close to 25.5 inches. Its body is often slightly smaller than a dreadnought acoustic guitar, but the wider neck can make the instrument feel larger in your hands.
Classical guitar sizes often include:
• Full-size classical guitar: about 38 to 40 inches
• Three-quarter classical guitar: about 36 inches
• Half-size classical guitar: about 32 to 34 inches
• Quarter-size classical guitar: about 28 to 30 inches
A classical guitar is not automatically a beginner guitar. It is a specific type of instrument with nylon strings, a flat fingerboard, and a traditional body design. Some beginners find it comfortable, while others prefer the narrower neck of a steel-string acoustic guitar.
How Long Is a Guitar for Kids?
A guitar for kids can measure from about 28 to 36 inches, depending on the child’s age and body size. These instruments are often called quarter-size, half-size, or three-quarter guitars.
Here is a simple guide:
• Quarter-size guitar: about 28 to 30 inches
• Half-size guitar: about 30 to 34 inches
• Three-quarter guitar: about 34 to 36 inches
• Full-size guitar: about 38 to 42 inches
