As a rough guide, preschoolers and kindergartners usually fit a quarter-size guitar, children in early elementary school a half size and older elementary kids a three-quarter size. By middle school, or once a child is around five feet tall, most can handle a full-size guitar. Kids grow at different rates, though, so two nine-year-olds may need different sizes. The easiest test is to have your child sit with the guitar on their leg. If they can reach the first fret with the elbow relaxed and slightly bent, and the other arm rests comfortably over the body of the guitar, the size is right.
Guitar sizes at a glance
Guitar sizes are usually described by fraction or by total length:
- 1/4 size, about 30 to 31 inches long: many 4- to 6-year-olds.
- 1/2 size, about 34 inches: many 6- to 8-year-olds.
- 3/4 size, about 36 inches: many 8- to 11-year-olds, and some petite teens and adults.
- Full size (4/4), about 38 to 41 inches: most kids 12 and up and adults.
Manufacturers vary a little, so treat these as starting points rather than strict rules.
How to check the fit in person
Have your child sit on a chair with feet flat on the floor and the guitar resting on their leg. Then look for these signs:
- They can reach the tuning pegs end of the neck and press the first fret with their left hand while the elbow stays slightly bent.
- Their right arm drapes over the body so the hand falls near the sound hole without the shoulder rising.
- The guitar does not cover their whole chest or force them to peek over the top.
- They can hold it for a few minutes without slouching or sliding the guitar off their knee.
If they have to lean forward or stretch to reach the first fret, the guitar is too big. If it looks like a toy and their fingers feel cramped between frets, it may be too small.
Why size matters so much
A guitar that is too large forces stretches small hands cannot make. Chords sound buzzy, the child presses harder to compensate and practice starts to feel like a battle. Kids in that situation often conclude they are “bad at guitar” when the instrument is the real problem.
When the guitar fits, a beginner can press chords cleanly. That means they get to real songs sooner, which helps a lot with motivation.
Nylon or steel strings?
Most young beginners start on a classical guitar with nylon strings. Nylon is softer and has less tension, so it hurts less to press the strings down. A steel-string acoustic is louder and brighter but harder on new fingers. Electric guitars also have light strings, although you need an amplifier. We compare the choices in acoustic or electric guitar for beginners, and sore fingertips are covered in why your fingers hurt when you play guitar.
Should you buy a bigger guitar to grow into?
It is tempting, but usually not a good idea. A guitar your child will “grow into” next year is the wrong size this year, which slows progress now. Kids typically move up a size every couple of years. Many families buy a modest-priced instrument in the current size and trade or pass it down when the child outgrows it.
One more thing: even a guitar that fits can be hard to play if the strings sit too high. Bring it to the first lesson and the teacher can tell you if it needs an adjustment.
Left-handed children
Plenty of left-handed kids play ordinary right-handed guitars without trouble, since both hands have hard jobs on guitar. Some feel more comfortable on a left-handed model. Before you buy, a teacher can have your child try both and see which feels natural.
