Electric and acoustic guitars are made in several types and sizes. Some designs are ideal for kids and others are specifically for adults. You might also wonder how long is a standard guitar?

There are no standard guitar sizes; instead, they are recognized as “full-sized” guitars. These are 38 inches in length with 25.5 inches in scale length. Every brand has its specific size and not all of them have the same measurement.

Before we discuss the guitar sizes, here are the topics we’re going to tackle that may answer your questions:

  • How Long Is a Standard Guitar? What is the size of a ‘full size’ guitar?

How Long Is a Standard Guitar?

There are no standard sizes labeled for every guitar. Each guitar brand has its signature size, design, and length. If you’re looking for a guitar that suits your size, it’s better to check it physically in stores.

A standard guitar often complicates the definition of full-size guitars. A full-size guitar, on the other hand, is the most appropriate term for what size is used in various brands. When checking for the size, make sure to ask the sales representative about the full size of the particular brand you’re eyeing for.

What is the size of a ‘full size’ guitar?

A full-size guitar has a length of 38 inches (96.5 centimeters) with 25.5 inches (64 cm) scale length. If you already purchased a guitar, you can determine it by measuring the scale length. Most guitar brands use this size range to recognize full-size types.

You can confirm your guitar as full-sized if the scale length reaches 25 (63 cm) inches or more. The length doesn’t influence this specific size. Whether it is longer than 38 inches or shorter, the scale length is the foundation to determine this specific measurement.

Some guitars have less than 25 inches in scale length. These types of guitars are called scaled-down guitars and they also have different classes. They are technically made for traveling purposes since they are more portable than full-sized guitars.

What are the different sizes of guitars?

Aside from the full-size guitars, there are other sizes that you need to take note of. These are the 4/4, 3/4, 1/2, and 1/4 sizes. The determined sizes are not exactly the smaller types of the full-sized ones.

  • 4/4 Guitar – These are full-size guitars. The other sizes are the smaller versions of this guitar type. It is used by the manufacturers as a base for their scaled-down guitars.
  • 3/4 Guitar – Compared to the full-size guitars, 3/4 guitars are somewhat a bit smaller. These types commonly have 36 inches. This is the second largest in the variety of guitar sizes.
  • 1/2 Guitar – 1/2 size guitars commonly have a measurement of around 33 inches. Keep in mind that this is not half of the full-sized guitars. This is kind of larger than 1/4 guitars, but smaller than 3/4 types.
  • 1/4 Guitar – The length of this guitar is around 31 inches and is considered the smallest model size among the others. 1/4 guitars possess a small scale length which is usually 19 inches. Similar to other types of guitars we mentioned, this is not the literal 1/4 size of the full-sized guitars.

The scaled-down types of guitars commonly are good for children. This doesn’t limit the usage as adults can also use it if they are comfortable with it.

How to Measure a Guitar

In measuring a guitar, all you should focus on is the total length and the scale length. These methods apply to acoustic and electric guitars.

Measuring a Guitar’s Total Length

To identify the guitar’s total length, measure it from the top of the headstock down to the end of the guitar body. You can use a tape measure to do this.

The common total length of the full-sized guitar ranges from 36 to 40 inches. The size of the headstocks greatly influences the length of the guitar. Take note that it doesn’t affect the feel when you play it.

Measuring a Guitar’s Scale Length

For a more accurate measurement, the scale length can provide more information on the guitar sizes. The parts that are incorporated are from the bridge down to the guitar nut.

What size guitar does a child need?

Guitar sizes are important for children since they are smaller compared to adults. It is difficult for them to play a full-sized guitar due to the longer scale length. This is why scaled-down models are recommended for them.
