Guitar Size Age Range Child Height Arm Length
1/4 Size 4-6 years 3'3" - 3'9" (99-114cm) Under 17"

Full Size 12+ years 5'+ (150cm+) 22"+

Quick Answer:

Guitar size is determined by your child's height: Under 3'9" = 1/4 size, 3'9"-4'5" = 1/2 size, 4'5"-4'11" = 3/4 size, 5'+ = Full size. When in doubt, go slightly smaller - comfort is key for beginners.

How to Measure

Stand your child against a wall with arm extended to the side. Measure from neck to middle of palm. This arm length determines guitar size more accurately than age alone.

Tips

  • Age is only a rough guide - height and arm length are more important
  • If between sizes, go smaller for comfort
  • A too-large guitar can cause bad habits and frustration
  • Have your child hold the guitar seated - it should feel natural

Frequently Asked Questions

How do I know if a guitar is too big for my child?

Signs a guitar is too big: child can't reach around the body comfortably; arm has to stretch to reach the soundhole; fingers can't press frets without straining; the guitar feels awkward or heavy.

Can my child use a larger guitar to grow into?

Not recommended. A too-large guitar causes poor technique, frustration, and can lead to bad habits. Kids grow through sizes relatively quickly anyway - stay with the right size.

What size guitar for a 7 year old?

Most 7-year-olds need a 1/2 or 3/4 size guitar, depending on height. Measure arm length for accuracy: 17-20 inches = 1/2 size, 20-22 inches = 3/4 size.
