1/2 vs 3/4 Violin: Sizing a Child Correctly
Half or three quarter violin? Size is set by arm length, not age. A violin that is too big makes correct left hand position impossible.
Quick Answer:
Violin size is decided by measuring the child's arm, not by their age. A half size typically suits children around six to nine and a three quarter around nine to twelve, and both ranges vary widely with build. An instrument that is too large forces the left elbow and wrist into positions that make good technique impossible and can cause genuine strain, so this is worth getting right.

How to measure for a violin
Have the child stand with their left arm out to the side, straight, palm up. Measure from the base of the neck to the middle of the palm. Shops and teachers publish charts converting that measurement to a size, and the rule is to take the smaller size when a child falls between two. A slightly small violin is playable; a slightly large one is not.
Why too large is worse than too small
Reaching for a violin that is too long pulls the left elbow out and forward and forces the wrist to collapse, which is exactly the position teachers spend years correcting. It also makes the fourth finger unreachable, so the student learns to shift when they should not. A slightly small instrument is cramped and it does not build habits that have to be unlearned.
Expect to change size
A child will typically go through two to four sizes before reaching full size, changing every year or two. That is normal and it is why so many families rent. Second hand fractional violins are plentiful for the same reason, since every family that bought one is selling it a couple of years later.
What changes with size and what does not
A smaller violin has a smaller body and produces a thinner, quieter sound, which is unavoidable and unimportant for a beginner. Everything else, the strings, the tuning, the technique, is the same. A child playing a well set up half size violin is learning exactly what a child on a full size is learning.
Our Verdict
Measure the child rather than guessing from their age, and take the smaller size if they fall between two. For most children around six to nine that means a half size and for most around nine to twelve a three quarter. Ask their teacher to confirm before ordering, since teachers size children every week and the measurement takes a minute.

Frequently Asked Questions
Can a child play a violin that is slightly too big?
They can hold it, and they cannot play it properly. The left hand position that makes intonation possible depends on the instrument fitting the arm, and stretching for it produces the collapsed wrist and raised shoulder that teachers spend years undoing. If in doubt, go smaller and change sooner.
Should we rent instead of buying?
For a young child who will change size two or three times, rental from a violin shop often costs less overall and includes setup, maintenance and size exchanges. Many shops also apply part of the rental towards an eventual purchase. The rent against buy page on this site sets out the arithmetic for different ages.
When does a child move to full size?
Usually somewhere between eleven and fourteen, depending entirely on their arm length rather than a birthday. Some smaller adults play a three quarter violin permanently and there is nothing wrong with that. The measurement decides it at every stage, not the age.
How was this guidance researched?
From sizing charts published by violin makers and shops, together with what teachers publish about fractional sizing. We have not taught violin and do not claim to have. The measuring method described here is the standard one used by shops, and a teacher confirming it in person is worth more than any chart.
