Your child has come home asking for violin lessons, or the school music programme has just sent out its instrument list. Now you’re staring at a wall of numbers — 4/4, 3/4, 1/2, 1/8, 1/10 — and none of them mean anything yet.
The good news: violin sizing is simpler than it looks. It comes down to one measurement, one comfort check, and one rule you shouldn’t break. Here’s how to get it right the first time.
Why size matters more than you’d think
A violin isn’t like a school uniform. You can’t buy one a little big and let them grow into it.
An oversized violin forces a child to stretch their left arm past a comfortable angle just to reach first position. Their wrist collapses, their shoulder creeps up, and their fingers can’t land cleanly on the string. The result is poor intonation, aching arms, and — most often — a child who quietly decides violin is “too hard” within a few months.
An instrument that fits does the opposite. The bow arm moves freely, the left hand stays relaxed, and the child’s attention goes where it belongs: to the sound they’re making.
How to measure your child at home
Grab a soft measuring tape. You’ll need your child and about thirty seconds.
Have your child stand up straight and extend their left arm out to the side, palm facing up, as if reaching for something on a high shelf beside them.
Measure from the base of the neck (where the neck meets the shoulder) to the middle of the left palm.
Write that number down in centimetres.
That measurement — the arm length — is what determines violin size. Two things to note: measure to the middle of the palm, not the fingertips, and always use the left arm, since that’s the one doing the reaching on a violin.
Violin size chart
| Violin size | Arm length | Typical age | Violin body length |
|---|---|---|---|
| 1/16 | 36–41 cm | 3–4 years | ~20.5 cm |
| 1/10 | 41–43 cm | 3–5 years | ~23 cm |
| 1/8 | 43–47 cm | 4–6 years | ~25.5 cm |
| 1/4 | 47–51 cm | 5–7 years | ~28 cm |
| 1/2 | 51–55 cm | 7–9 years | ~31 cm |
| 3/4 | 55–58 cm | 9–11 years | ~33.5 cm |
| 4/4 (full) | 58 cm and above | 11+ years | ~35.5 cm |
Read the arm length column first. Age is only a rough guide — children of the same age can easily be two sizes apart, and a tall seven-year-old may sit comfortably on a 1/2 while a smaller classmate needs a 1/4.
If your child falls between two sizes, choose the smaller one. A slightly small violin is playable. A slightly large one teaches bad habits that take years to unlearn.
The scroll test: a second opinion
Once you have a violin in hand, do this check before committing:
Have your child hold the violin in playing position, tucked under the chin and resting on the left shoulder. Ask them to extend their left arm and curl their fingers around the scroll — the carved spiral at the very end.
- Fingers wrap comfortably around the scroll with a slight bend at the elbow → good fit.
- Arm is locked straight, fingers barely reaching → too big.
- Elbow is sharply bent, arm feels cramped → too small.
A child should be able to hold this position for a few seconds without strain. If they can’t, the size is wrong regardless of what the tape measure said.
Three mistakes parents make
Buying big to “save money later.” Understandable, but it backfires. Children typically move up a size every 1–2 years in the early stages, so no single instrument lasts anyway — and the oversized one may cost you a student who gives up.
Skipping the teacher’s opinion. Teachers see hundreds of small hands. Bring your child’s measurement to the first lesson and ask the teacher to confirm before you buy.
Buying the instrument alone. A violin is useless without a bow, rosin, and a case. Sold separately, these add up fast. Outfits that bundle them are almost always the better value for a beginner.
Choosing the instrument itself
For a genuine beginner, look for three things: a solid carved spruce top (not laminate or plywood, which sounds dull and lifeless), ebony fittings including the fingerboard and pegs, and a proper shop setup — meaning the bridge is fitted, the pegs turn smoothly, and the strings sit at a playable height. An unfitted violin bought online sight-unseen often needs a setup that costs a good fraction of the instrument itself.
Instruments to consider from Gramercy Music
Eurostring M200 Violin — from $220
The natural starting point. It has a handcrafted solid spruce top, flamed maple back and sides, ebony fittings and fingerboard, and a carbon tailpiece with four fine adjusters — those adjusters matter more than you’d expect, since they let a child tune without wrestling with the pegs.
Crucially for young beginners, it’s available across the full range of fractional sizes: 4/4, 3/4, 1/2, 1/4, 1/8 and 1/10.
It also ships as a complete outfit. Included with purchase:
- Eurostring Violin Bow Model 780 (matched to size)
- Walter Geipel Paganini Violin/Viola Cork Rosin
- Lightweight oblong violin case (matched to size)
That’s everything needed for a first lesson in one box.
Eurostring M300 Violin — from $500
A step up in tonal quality and finish. Worth considering if your child has already had a term or two of lessons, is clearly committed, and has reached one of the larger fractional sizes where they’ll stay a while.
Eurostring M400 Violin — from $730
For the student preparing for graded exams or joining a school ensemble, where projection and tonal colour start to be assessed.

The accessories that actually get used
A bow. Beginner outfits include one, but bows wear out and hairs break. When it’s time for a better one, the Rosenberger Violin Bow covers sizes 4/4 down to 1/4 and is a meaningful upgrade over a starter stick.
Rosin. Non-negotiable. Without rosin the bow slides silently across the string, and more than one parent has assumed a violin was faulty for exactly this reason. The Guillaume Violin/Viola/Cello Rosin comes in a metal box that survives being thrown in a school bag.
A practice mute. If your child practises in an HDB flat or a condo with thin walls, a rubber practice mute is one of the cheapest purchases you’ll ever be grateful for.
A music stand. Reading music off a bed or a dining table encourages hunching. A proper stand like the Alges Nocturne sets the posture correctly from day one.
A better case. Once your child reaches 4/4 and is carrying the instrument to school and lessons daily, a protective case such as the G&G Shaped Carbon Fibre Case becomes a sensible investment.
Caring for a violin in Singapore’s climate
Our humidity is generally kinder to string instruments than dry winter climates, but air conditioning creates the real risk: rapid swings between a humid outdoors and a cold, dry, air-conditioned room. Wood expands and contracts, seams open, and pegs slip.
A few habits that help:
- Wipe rosin dust off the strings and body after every practice session with a dry, soft cloth.
- Keep the violin in its closed case when not in use — never leaning against a wall or lying on a bed.
- Loosen the bow hair after playing, every single time.
- Don’t store the case directly under an air-con unit or in a car.
When to size up
Watch for these signs, which usually appear before you’d expect:
- Your child’s fingers no longer wrap comfortably around the scroll.
- The left elbow looks locked or over-extended in playing position.
- They complain of shoulder, neck, or arm fatigue after short sessions.
- Their teacher mentions it — teachers almost always spot it first.
Re-measure every six months during growth spurts. Most students pass through three to five sizes before reaching a full-size instrument.
Frequently asked questions
Should I rent or buy?
Renting can make sense for the smallest sizes, which a child may outgrow within a year. By 1/2 or 3/4, buying usually works out better, and a well-cared-for instrument holds resale or trade-in value.
My child is 6 but very tall. Which size?
Measure the arm, not the birthday. A tall six-year-old might well be on a 1/4 or even a 1/2. The tape measure is the authority here.
Can I just order online without trying it?
You can, and sizing by measurement is reliable. But if you’re near enough, bringing your child in to hold a few sizes takes ten minutes and removes all doubt — particularly if they’re on the border between two sizes.
Still unsure? Ask.
Sizing a child’s first violin is the kind of decision that’s much easier with someone experienced looking at your actual child holding an actual instrument.
The team at Gramercy Music can help you match the right size and instrument, and can advise on setup, repairs and upgrades as your child grows.
