What Size Guitar Do I Need?

Most adults use a full-size 4/4 scale guitar, while children use smaller sizes based on their size and age. Guitar sizes are 1/4, 2/4, 3/4 and 4/4 scale.

Selecting a guitar to play depends partly on the size of the instrument. An instrument that is too large or small is difficult to play properly, making the experience of learning to play unpleasant. Luckily, most adults only need to purchase a full size guitar measuring 38 to 42 inches in length. While some smaller adults may be more comfortable with a 3/4 size guitar ranging between 34 and 36 inches in length.

However, kids need guitars of all different lengths to suit their size and arm length. Guitar sellers often recommend sizes by age range.

For instance, 1/4 size is suitable for ages 4 to 6, and height ranges 3 feet and 3 inches to 3 feet and 9 inches. These guitars are about 31 to 32 inches long. The 2/4 or 1/2 size is suitable for kids between 5 to 9 years old, and 3 feet and 10 inches to 4 feet and 5 inches tall. These guitars are between 33 to 36 inches long.

Older kids between 8 to 12 years of age can handle the 3/4 size guitar. This instrument is also suitable for height ranges between 4 feet and 6 inches to 4 feet and 11 inches. Finally, the full-size 4/4 guitar is suitable for ages 11 and up, and those 5 feet and above.
