Which violin size fits a child? Arm length is a more useful guide than age, but no chart replaces trying the instrument. Yamaha pairs approximate arm measurements with seven sizes from 1/16 to 4/4; posture and the ability to reach around the scroll help decide between sizes.
Measure from the neck to the middle of the palm, use the guide as a starting point, then check the violin with the player. The arm should not have to stretch fully to reach the scroll.
| Violin size | Arm length, approx. |
|---|---|
| 1/16 | 36 cm |
| 1/10 | 39 cm |
| 1/8 | 43 cm |
| 1/4 | 47 cm |
| 1/2 | 52 cm |
| 3/4 | 57 cm |
| 4/4 | 60 cm |
01Why size is decisive
A violin that is too large can make a relaxed posture harder. The key is whether the player can reach the positions without overextending; fit and posture matter more than buying a size to grow into.
A suitable size allows a relaxed playing posture. Check that the player can reach the positions without overextending. Choosing a larger violin to grow into is not automatically the better option.
02How to measure the right size
Measure from the neck to the middle of the palm. Yamaha uses this as a guide in its size chart. The figures help narrow the choice; they are not strict cut-offs.
Place the violin under the chin and ask the player to wrap a hand around the scroll. The elbow should stay slightly bent. If the reach feels difficult, treat the chart as a starting point: posture and reach matter too. A music teacher can help choose between sizes when the fit is uncertain.
03Popular sizes in the shop
For comparison, these links show the same GEWA series in three sizes: Ideale 1/2, Ideale 3/4 and Ideale 4/4. Check the size and set details for each option.
This series is available in several sizes. When moving up, check the fit again against current arm length and playing posture.



04Check the fit with the instrument
The chart above narrows down the options. Then check the violin in playing position: the player should reach the scroll comfortably with the elbow slightly bent.
Once the fit is right, keep arm length in mind as the player grows. Check reach again in playing position when it is time to move to the next size.
