What Size Violin Does My Child Need? A New Zealand Parent's Sizing Guide
A practical guide to measuring your child for the right violin size, with a complete size chart from 1/16 to full size and tips on when to size up.
Why Violin Sizing Matters
Violins come in eight different sizes, and getting the right one for your child is genuinely important. A violin that's too large will be uncomfortable to hold, difficult to play, and can even cause strain in the neck, shoulder, and arm. A violin that's too small won't produce the sound quality your child needs to develop properly, and they'll outgrow it within weeks.
The good news is that sizing a violin is straightforward once you know the method. You don't need to be musical yourself — just a tape measure and five minutes.
How to Measure Your Child for a Violin
The most reliable method is the arm-length measurement. Forget age charts on their own — children of the same age can vary hugely in size, and arm length is what actually determines which violin fits.
The Arm-Length Method (Step by Step)
- Have your child stand up straight with their left arm extended fully to the side, parallel to the floor.
- Turn their palm so it faces upward, as if they're holding the violin scroll.
- Measure from the base of their neck (where the neck meets the shoulder) to the centre of their left palm.
- Record the measurement in centimetres.
- Use the size chart below to find the right violin size.
Tip: If your child is between sizes, it's almost always better to go with the smaller size. A slightly smaller violin that's comfortable to play will serve them far better than one that's a stretch.
Violin Size Chart
| Violin Size | Typical Age Range | Arm Length |
|---|---|---|
| 1/16 | 3 – 4 years | 35 – 38 cm |
| 1/10 | 4 – 5 years | 39 – 42 cm |
| 1/8 | 4 – 6 years | 43 – 46 cm |
| 1/4 | 5 – 7 years | 47 – 51 cm |
| 1/2 | 7 – 9 years | 52 – 56 cm |
| 3/4 | 9 – 11 years | 57 – 60 cm |
| Full Size (4/4) | 11+ years | 60 cm+ |
A note on ages: The age ranges above are rough guides only. We've seen tall seven-year-olds on 3/4 violins and petite eleven-year-olds still comfortable on a 1/2. Always measure — don't guess based on age alone.
What About the Scroll Test?
If you have access to a violin (perhaps at a music shop or your child's school), there's a quick physical test you can do as well:
- Have your child hold the violin in playing position, tucked under their chin.
- Ask them to extend their left arm along the length of the violin toward the scroll.
- Their fingers should be able to curl comfortably around the scroll with a slight bend in the elbow.
If their arm is fully straight and they can barely reach the scroll, the violin is too big. If their elbow has a very pronounced bend and they seem cramped, it may be too small.
When to Size Up
Children grow, and part of learning violin is progressing through sizes. Here are the signs that it might be time to move up:
- Their arm is fully extended when reaching the scroll, with no bend in the elbow.
- They're struggling to reach first position comfortably — their fingers seem crowded or stretched.
- Their teacher suggests it — violin teachers are experienced at spotting when a student has outgrown their instrument. Trust their judgement.
- The sound quality has changed — a violin that's too small for the player can sound thin or forced.
This is one of the biggest advantages of renting. When your child outgrows their current size, you simply swap to the next one up rather than selling the old instrument and buying a new one. It takes the stress (and the cost) out of the process entirely.
Common Sizing Mistakes
Buying big "so they'll grow into it"
This is the most common mistake parents make, and it's completely understandable — nobody wants to buy something their child will outgrow in a year. But an oversized violin is genuinely harmful. It forces bad technique, creates tension in the hand and shoulder, and makes playing unpleasant. Your child's teacher will likely ask you to get the right size anyway.
Relying on age alone
Online charts that list only age ranges are a rough starting point at best. Two six-year-olds can easily need different sized violins. Always measure the arm.
Measuring incorrectly
Make sure you're measuring from the neck to the palm, not to the fingertips. And ensure your child's arm is properly extended — if they're slouching or holding their arm at an angle, you'll get an inaccurate reading.
What About Viola and Cello Sizing?
Violas and cellos have their own sizing systems. Viola sizes are typically measured in inches (body length) rather than fractions, and cello sizing follows a similar fractional system to violin but with different arm-length correspondences. If your child is starting viola or cello, ask their teacher for a sizing recommendation — or get in touch with us and we can help.
Ready to Find the Right Violin?
Once you've measured your child and know what size they need, take a look at our violin range to see what's available. We carry student, intermediate, and professional violins in all standard sizes, and every instrument is professionally set up before it reaches you.
If you're still unsure about sizing, don't worry — it's always better to ask than to guess. Your child's violin teacher is the best resource, and we're always happy to help as well.
