Guitar Size Chart by Types of Guitars: what size do I need?

Why is a good guitar size important? The size of different guitars kinds varies.
Electric guitars are substantially smaller than steel-string acoustic and nylon-string classical guitars; nonetheless, you must consider the added weight. Electric guitars are smaller but made of solid wood, making them slightly heavier. Acoustic guitars are larger but hollow. There is a wide range of sizes available for guitars, and the playability of your particular instrument is significantly impacted by its dimensions (skip straight to the Guitar Size Chart).

Different Kinds Of Guitars

Suppose you wish to perform in a range of genres. In that case, it is vital to have many guitars, typically of different varieties, which is why many guitarists possess more than one guitar (rock, classical, and country music all require different types of guitar).

However, when you are first beginning to study guitar, selecting one style of guitar is preferable and staying with it until you have learned the fundamentals of playing the instrument.

It is suggested that beginners begin their guitar studies on a classical (nylon string) guitar because of the instrument’s striking resemblance to the first guitar. The most common varieties of guitars are:

Classical Guitar (Nylon String)

The nylon strings on the classical guitar give it a very warm, mellow tone with a long sustain. It is often a little bit smaller than a steel-string acoustic guitar.

Steel strings should never be used on a classical guitar because they might harm the neck, which is how this kind of guitar is played.

It is traditional to play the classical guitar by plucking the strings with the fingernails, and very intricate and emotionally charged melodies characterize the music produced in this technique.

Because a significant portion of the repertoire for classical guitar is composed using notation, it is necessary to learn how to read notes.

Acoustic Instrument (Steel String)

Acoustic guitars don’t require an amplifier since their resonating body cavities amplify the strings’ sound. This kind of guitar is known as a steel-string acoustic guitar.

Acoustic guitars with steel strings are often used for accompaniment since they are louder than their nylon-stringed counterparts. Steel-stringed acoustic guitars are also more durable. They are also capable of being used for one-on-one musical performances.

Although the pick (plectrum) is the instrument of choice for most players of steel string guitars, a significant number of guitarists also use fingerstyle methods when playing these guitars.

Electric guitars

The sound produced by an electric guitar is not due to the instrument’s natural ability to produce sound; rather, it is the consequence of the sound being amplified by electrical means. In addition to an electric guitar, you will also need to get an amplifier.

Many electric guitars designed for beginners come with a tiny practice amplifier, but you may also purchase an amplifier separately. Accessories, such as a variety of effects pedals, are also used by electric guitarists.

How to Measure a Guitar?

There are primarily two methods for measuring a guitar:

  • The first method measures the guitar’s overall length from end to end. The scale length can be measured as a second method.
  • Knowing the total length is useful, but understanding the scale length is significantly more important.

The Total Length of a Guitar

To determine a guitar’s overall length, we measure from the top of the headstock to the bottom of the body. Measure the distance between the strings using a tape measure. The entire length is measured from the body’s outer side to the tip of the headstock.

A “full size” guitar’s overall length can range from 36 inches to well over 40 inches.

Comparing guitar sizes by total length is not useful, as this parameter doesn’t affect the way you play the guitar

Guitar size: the Scale Length of a Guitar

Checking a guitar’s scale length is a more accurate method of measurement. Because it affects how a guitar feels when you play it, the scale length is the most crucial measurement for a guitar. Even a slight scale length change can have a different sensation when playing.

From the bridge to the nut of the guitar, you measure the scale length of the instrument.

Taylor Acoustic Guitar

Taylor guitars are available in five unique body shapes and designs. The following is a fast reference for our shapes.

The body dimensions of a guitar are essential for two primary reasons: 1) They assist in shaping its voice; 2) The resultant “fit” concerning your body will affect the physical comfort of playing.

The five body designs offered by Taylor span from the tiny Grand Concert to the large and sculpted Grand Orchestra. Compare guitar body sizes, curves, and depth against your body and your picking arm stretched over the bottom.

Smaller guitar bodies generate a more controlled sound with more upper-end chime, while bigger bodies are louder with greater low-end depth.

However, do not dismiss a body type too quickly before playing it. You may be shocked by a smaller body’s tone, depth, and loudness, or a bigger body’s responsiveness.

Full-size classical guitars have wider necks than other varieties. We suggest that you get your kid a narrow-neck classical guitar if their hands are on the smaller side because:

  • It is excellent for the music of classical, flamenco, and Spanish traditions.
  • The smallest size, the 1/4 size, is available.
  • It is soft on the skin, making it an excellent option for young children.
  • It sounds mellow and mild and is not as loud as an acoustic instrument would be.

What Exactly Is A Full-Sized Guitar?

Full-size guitars are typically 38 inches long with a scale length of 25.5″. All you need to do to determine if your guitar is full-size or not is to measure the scale length. In most circumstances, a guitar with a scale length of roughly 25 inches is considered a full-size instrument.

Now that we’ve covered the two most common methods of guitar measurement, let’s move on to full-size instruments. The reason for the importance of this phrase is that guitar sizes are based on full-size instruments.

The fundamental issue here is that there is no uniform number for full-size guitars, and it varies by model and manufacturer. A normal Fender Stratocaster, for example, is a full-size guitar, but the same is true of the Gibson ES-335.

Should You Get Your Child a Regular-Sized Guitar?

There are other choices available than purchasing a guitar sized appropriately for a youngster, even if it would make perfect sense. Purchasing a guitar of standard size is another choice you have.

Some guitar instructors are certain that bigger guitars would slow down a child’s development as a guitarist. Other instructors will tell you that youngsters can learn efficiently on guitars that are greater in size.

One of the many advantages of purchasing one is that your kid will never outgrow a full-sized guitar. That means you won’t have to purchase another guitar in the future, and there’s a good chance your kid will keep playing the one they started on for the rest of their lives.

In terms of sound quality, full-sized guitars are clearly superior to their scaled-down counterparts. A 1/4 or 1/2-sized guitar has a quite monotonous sound, and as your child’s ear grows, they run the risk of losing inspiration due to a guitar that has a monotonous sound.
