What Size Acoustic Guitar for Adults

For adults, the recommended size for an acoustic guitar is usually a full-size or dreadnought guitar. This size offers a comfortable playing experience and is suitable for most adult players.

Choosing the right acoustic guitar size is crucial for adults who wish to learn or play the instrument. Whether you are a beginner or an experienced musician, having the correct size guitar ensures better playability and comfort, ultimately enhancing your overall playing experience.

Among the various sizes available, the full-size or dreadnought acoustic guitar is typically the most suitable for adults. With a full-size acoustic guitar, you can expect a balanced tone, ample projection, and a comfortable fretboard that accommodates adult-sized hands. So, let’s delve into the details of why the full-size or dreadnought acoustic guitar is typically the best choice for adult players.

Factors To Consider When Selecting An Acoustic Guitar

Factors to Consider When Selecting an Acoustic Guitar

Body Size And Shape

One of the crucial factors to consider when selecting an acoustic guitar is the body size and shape. The size and shape of the guitar body determine the overall sound projection, tonal quality, and comfort while playing. Different body sizes and shapes offer unique characteristics that cater to various playing styles and preferences.

Scale Length

The scale length of an acoustic guitar refers to the distance between the nut and the bridge. This measurement affects the string tension and the space between the frets, ultimately influencing the playability and intonation of the instrument. Shorter scale lengths are ideal for players with smaller hands or for those who prefer a lighter touch, while longer scale lengths provide more string tension and may be better suited for fingerpicking and strumming with a heavier attack.

Neck Width And Thickness

The neck width and thickness play a significant role in determining the comfort and playability of an acoustic guitar. A wider neck width allows for greater finger spacing, making it easier to play complex chords and fingerstyle techniques. On the other hand, a narrower neck may be more suitable for players with smaller hands or those who prefer faster and more precise playing. Additionally, the thickness of the neck affects the overall feel and grip while playing, with thinner necks often preferred for faster playing styles.

When selecting an acoustic guitar, it is important to take into account these factors to ensure that the instrument suits your playing style, comfort, and individual preferences. Consider what body size and shape resonate with you, the scale length that complements your desired tone and playability, and the neck width and thickness that align with your hand size and playing technique. By understanding and choosing these elements wisely, you can find the perfect acoustic guitar that enhances your musical journey.

It has a more comfortable body size than a Dreadnought, making it easier to hold, especially for players with a smaller build. Concert guitars typically have a length ranging from 19 to 20 inches. Despite their smaller size, they can still produce a vibrant and balanced tone. They are often favored by fingerstyle players for their responsiveness and clarity.

It features a slightly smaller body than a Dreadnought, making it easier to handle, while still delivering a rich and resonant tone. This size is favored by musicians who value both comfort and versatility.

Grand Auditorium

The Grand Auditorium size is similar to the Auditorium, but with subtle differences in shape and size. It typically has a length ranging between 19 and 20 inches. The Grand Auditorium offers a versatile sound with enhanced mid-range presence. Its slightly larger body size allows for increased projection and volume, making it suitable for both strumming and fingerpicking.

How The Guitar Size Affects Playability And Sound


When it comes to playing the acoustic guitar as an adult, choosing the right size instrument is crucial. The size of a guitar not only affects how comfortable it is to play but also directly impacts the sound and projection it produces. In this article, we will dive into the intriguing relationship between guitar size and its impact on playability and sound.

Impact on comfort and reach

Impact On Comfort And Reach

Choosing the correct size acoustic guitar ensures optimal comfort during extended playing sessions. A guitar that is too large or too small can lead to strain and discomfort, making it challenging to focus on your playing. Luckily, with the wide range of adult-sized guitars available, there are options to fit every body type and preference.

A smaller-bodied guitar can be ideal for those with smaller hands or a shorter wingspan. These guitars typically have a narrower neck, making it easier to wrap your hands around the fretboard and form chords. Similarly, if you have a larger build or longer arms, a larger-bodied guitar provides ample space for your hands to maneuver without feeling cramped.

Influence on tone and projection

Influence On Tone And Projection

Not only does the size of a guitar affect comfort, but it also plays a significant role in shaping the instrument’s tone and projection. Different-sized guitars produce unique sound characteristics, allowing players to explore a range of sonic possibilities.

A smaller-sized guitar, such as a concert or parlor model, tends to deliver a warm and intimate tone. These guitars are often favored by fingerstyle players or those who enjoy light strumming. In contrast, larger-bodied guitars like dreadnoughts or jumbos offer more volume and a booming low end, making them suitable for genres that require a fuller sound, such as country or bluegrass.

It’s worth noting that the size of the guitar also affects its projection, or how well the sound carries. A smaller guitar may have a more focused projection, which can be desirable for solo performances or intimate settings. On the other hand, larger-bodied guitars tend to project sound more forcefully, making them well-suited for live performances or playing alongside other instruments in a band setting.


By considering the impact of size on comfort, reach, tone, and projection, you can make an informed decision on the right acoustic guitar size for your needs. Whether you opt for a smaller-bodied guitar for its intimate sound or a larger one for its ample projection, finding the perfect fit will enhance your playing experience and bring out your musical expression.

Determining The Ideal Guitar Size For Your Body Type

When it comes to playing the acoustic guitar, finding the right size that suits your body type is crucial. Playing a guitar that is too big or too small for you can make the learning process more challenging and may even impact your overall playing experience. To ensure that you embark on your musical journey with the perfect fit, it is essential to determine the ideal guitar size for your body type. This not only helps in achieving comfort and ease while playing, but also contributes to better technique and sound quality.

Tips For Measuring Yourself

To accurately determine the ideal guitar size for your body type, it is important to know how to measure yourself properly. Here are a few tips to guide you:

  1. Measure your height with a measuring tape or a ruler
  2. Measure the distance between your shoulder and the tip of your extended arm
  3. Check the length of your fingers, especially if you have shorter or longer fingers than average

Ensuring accurate measurements is crucial, as it will help you identify whether you fall into the category of a smaller or larger body type and guide you in making the right selection.

Recommended Guitar Sizes For Different Body Types

Now that you have gathered your measurements, let’s explore the recommended guitar sizes for different body types:

Body Type Recommended Guitar Size
Petite/Small Build 1/2-Size or 3/4-Size Guitar
Medium Build 3/4-Size or Full-Size Guitar
Tall/Large Build Full-Size or Jumbo Guitar

For those with a petite or small build, a 1/2-size or 3/4-size guitar would be more suitable, ensuring better reach and comfort. Medium build individuals can opt for a 3/4-size or full-size guitar, depending on their personal preference. Lastly, tall or large build musicians should consider a full-size or jumbo guitar to accommodate their body proportions.

Remember, these recommendations are general guidelines, and it’s essential to try out different guitar sizes to find the one that feels the most comfortable for you. Ultimately, finding the ideal guitar size for your body type is a personal choice that depends on how you feel while playing.
