How Big Is An Acoustic Guitar

Have you ever wondered how big an acoustic guitar really is? Guitars come in all sorts of sizes and shapes, each with its own special sound.

We’re going to explore the different sizes of acoustic guitars, from the big Jumbo to the small Parlor. By the end, you’ll know all about these cool guitars and which size might be just right for you! Let’s start!

How Big Is An Acoustic Guitar – Common Shapes and their Sizes


The Dreadnought is a popular acoustic guitar shape known for its large size and robust sound. Characterized by a broad square-shouldered design, it typically measures around 20 inches in body length, with a lower bout width over 16 inches and a depth of about 4 inches.

This size gives the Dreadnought a powerful, driving sound with a strong bass, making it a favorite for strummers and flatpickers in genres like country, rock, and bluegrass.

Concert Guitar

The Concert guitar, smaller than the Dreadnought, offers a more controlled and balanced tone. It usually measures about 18 inches in body length, with a lower bout width around 13 to 14 inches.

This smaller size makes it comfortable to play, especially for players with a smaller frame or those seeking a more intimate sound. Its balanced tone is well-suited for fingerstyle playing and lighter strumming.

Grand Auditorium

The Grand Auditorium guitar strikes a balance between the Dreadnought and Concert sizes. It typically has a body length of about 19 inches, with a lower bout width around 15 inches.

This shape offers a versatile sound that’s well-rounded, making it suitable for both strumming and fingerpicking styles. The Grand Auditorium is a popular choice for its ability to handle a wide range of musical genres and playing techniques.

Parlor Guitars

Parlor guitars are the smallest among the standard acoustic guitar shapes, ideal for players seeking a compact size and a softer, more articulate sound.

They generally measure about 18 inches in body length, with a lower bout width around 13 inches, and are more comfortable for seated playing and easy handling. Their size lends to a focused, sweet sound, perfect for blues, folk, and fingerstyle music.

Classical Guitars

Classical guitars, known for their nylon strings, have a distinctive size and shape that differ from steel-string acoustics. They usually feature a body length of about 19 inches, with a lower bout width approximately 14 to 15 inches.

Classical guitars have a wider neck, which facilitates the intricate fingerpicking often used in classical and flamenco music. Their size contributes to a soft, warm tone, making them a favorite for classical music enthusiasts and players who prefer a gentler sound.


Jumbo guitars are among the largest of the acoustic guitar types, renowned for their powerful volume and deep, resonant bass. They typically measure over 21 inches in body length and around 17 inches in lower bout width.

This large size allows for a rich, full sound with strong projection, making Jumbos a great choice for performance settings where volume and full-bodied sound are desired, such as in country and rock music.


Travel and Miniature guitars are designed for portability and ease of playing, especially for those on the go. They generally have a body length of around 15 to 17 inches, with a correspondingly smaller lower bout width.

Despite their compact size, these guitars are crafted to deliver a quality sound, though with less projection than full-sized guitars. They are ideal for traveling musicians, children, or as a convenient practice instrument.

Why Do Acoustic Guitars Have Different Sizes?

Acoustic guitars come in various sizes to cater to a wide range of musical styles, player preferences, and physical needs. Different sizes affect the guitar’s sound, playability, and portability.

Larger guitars like the Jumbo offer a deeper, louder sound suitable for strumming and rhythm playing, while smaller ones like Parlor guitars are favored for their clear, articulate tones, ideal for fingerstyle and solo performances.

The variety in sizes allows guitarists to choose an instrument that best suits the genre they play and the sound they wish to produce.

Factors to Consider When Choosing an Acoustic Guitar Size

When selecting the size of an acoustic guitar, consider your body size and hand comfort. Larger guitars might be uncomfortable for smaller players, while smaller guitars may lack the volume needed for certain styles.

Think about the style of music you play: fingerstyle guitarists might prefer smaller, more articulate guitars, whereas strummers might lean towards larger, louder guitars. The guitar’s tone and its compatibility with your musical taste are also crucial factors in choosing the right size.

Why Have Just One?

Owning multiple guitars of different sizes and shapes can greatly enhance a musician’s versatility and adaptability. Different guitars offer distinct tonal characteristics, making them suitable for various musical genres and playing styles.

For example, a Dreadnought might be ideal for a powerful strumming session, while a Concert guitar could be better for intricate fingerpicking. Having a range of guitars allows you to choose the most appropriate instrument for each musical context.

Tips for Determining the Right Acoustic Guitar Size for You

Choosing the right acoustic guitar size involves balancing comfort, sound, and playability. Test various guitar sizes to see which feels most comfortable in terms of body fit and neck width.

Consider the type of music you play and the sound you aim to achieve. Also, think about where you’ll be playing – if you travel often, a smaller guitar might be more practical.

Seeking advice from experienced players or guitar teachers can also provide valuable insights into finding the best fit for you.

In The End

It’s important to remember that personal preference and comfort play a significant role in choosing a guitar, and what works for one player may not suit another. It does make a difference if you have small hands or long fingers, if you are looking for a guitar for a child or for yourself, if you are small in stature, or 6’4”.

Trying out different guitars and trusting your own experience is often the best way to find the perfect instrument.
