"What size violin does my child need?" It's by far the most common question we hear in the violin department. And the worry behind it is real: children's violins come in fractional sizes, from 1/32 up to 4/4, and one that's the wrong size is hard to hold, sounds out of tune, and can kill the appetite for practice in those crucial first months, just when it's being decided whether the child takes to the violin.
The good news: the right size isn't a guess, it's a measurement. All you need is a soft tailor's tape measure and two minutes. This guide shows you how to measure at home, why a violin that's too big is worse than one that's a bit small, what changes from one size to another, and which sets we recommend at each step, based on our real sales. And if it's not yet set in stone that violin is the instrument, we've written a separate guide to choosing the right instrument by age.
Measure the arm, not the age
This is the method luthiers and teachers have used for generations: have your child stand straight and stretch their left arm out to the side, parallel to the floor, palm up. Measure from the base of the neck to the middle of the palm: that's the maximum size violin they can handle. If you measure only to the wrist, you get the comfortable size – the one the arm can manage without stretching. If the two measurements point to different sizes, always choose the smaller one.
Why the arm and not age? Because two seven-year-olds can easily have a ten-centimetre difference in arm length, and the violin is held with the arm, not the birth certificate. The ages in the table are just a starting point, and the centimetre ranges can vary slightly from chart to chart – another reason to pick the smaller size if you're on the border.
| Size | Arm (neck → middle of palm) | Approximate age |
|---|---|---|
| 1/8 | 43–47 cm | 4–6 years |
| 1/4 | 47–51 cm | 5–7 years |
| 1/2 | 51–56 cm | 7–9 years |
| 3/4 | 56–60 cm | 9–11 years |
| 4/4 | over 60 cm | from 11 years |
Below 1/8 there are also 1/16 and 1/32 sizes, for three- to four-year-olds. They're in our catalogue, but at these very small sizes stock comes and goes, and our shelf usually starts at 1/8; each product page shows current availability. At this age, we recommend checking with your teacher before buying, as even six months of growth can make a difference.
Why not buy a violin "to grow into"?
This is the most common sizing mistake we see, and it seems logical: kids grow, violins don't, so why not buy a bigger one right away? Because with a violin that's too big, the left arm is stretched to its limit, fingers can't reach the right spots on the fingerboard, and intonation suffers – not from lack of talent, but from geometry. The shoulder and neck compensate, tension builds up, and the teacher ends up correcting posture every lesson, when the instrument itself makes it impossible.
We see the end of this story in the shop: the parent comes back after a few months to buy the right size, and the child has lost exactly the period when motivation is most fragile. If you're going to make a mistake, err on the small side – a slightly smaller violin can still be played correctly, but one that's too big can't.
What changes from one size to another
A 1/4 violin isn't a toy or a different instrument: it's the same violin, just scaled down. The body, string length, and finger spacing all shrink proportionally, but the tuning stays the same: G–D–A–E. When a child moves from 1/2 to 3/4, they don't start over – they play the same pieces, just with slightly bigger finger distances.
Everything around the violin is also scaled, and this is where buying mistakes happen. Strings are size-specific, with separate categories for 4/4 string sets, 3/4 and 1/2 strings, and 1/4, 1/8, and 1/16 strings. The bow, case, and shoulder rest all have their own sizes. That's why complete sets are so convenient for beginners: all the accessories are matched to the violin size.
Our recommendations by size
Below are the violins and sets we recommend at each step, chosen from our real sales – not from internet top lists. The cards below each paragraph show up-to-date price and stock, so we won't repeat them in the text.
Size 4/4 (from 11 years)
If the arm measures over 60 centimetres, you're ready for a full-size violin. Our top recommendation here is the Stagg VN-4/4 set: solid maple back and ribs, solid spruce top, and in the box you get a protective foam case, a bow and rosin. It's the student violin we consistently sell, and the VN family also covers the 3/4 and 1/2 sizes at the same price level, which makes moving up a size later easier.
If you're on a tight budget, the Flame MV012L is one of the most affordable complete 4/4 sets we offer: spruce plywood top, maple plywood back, aluminium fine tuners, plus case, bow, and rosin. For the first year of study, it does the job without frills.
And when the student is committed and ready for a serious instrument, the top tier comes from Hora, the musical instrument factory in Reghin: spruce and flamed maple from the Carpathians, wood dried naturally for 5–10 years, ebony fingerboard, tuning pegs and tailpiece, finished with an oil varnish. One honest caveat – here you're buying just the violin: bow, case, and other accessories are added separately.
Size 3/4
For 3/4, our pick is the Hidersine Inizio set: violin with laminated spruce top and laminated maple body, with case and bow included. Stock at this size comes and goes, so check the card below for current availability. The Stagg VN series above also comes in a 3/4 size.
Size 1/2
For 1/2, it's the same Stagg recipe as the full size: solid maple and spruce, with case, bow, and rosin included. Roughly, this is the size for primary school years, about seven to nine years old.
Size 1/4
For 1/4 we recommend the Dimavery Complet set: violin with chinrest, maple body, bow, rosin, and waterproof foam case. The manufacturer recommends it from four to five years old.
Size 1/8
The smallest size we usually keep in stock is 1/8. The Dimavery Complet 1/8 set includes a veneered maple violin, wooden bow, rosin, and foam case; the violin itself weighs under a kilogram. The manufacturer recommends it from three to four years old; by our chart, it's for four years and up.
Complete set or separate pieces?
For a first violin, our answer is almost always the set: violin, bow, case, and often rosin, all in one box and all the right size. This avoids the classic risk of mismatched accessories, like a bow that's the wrong size, and your child can go to their first lesson with everything they need. If your child is starting at a music school, it's still worth checking with the teacher before ordering: some schools lend instruments for the first year, and many teachers prefer to see the child first – a quick chat can save you from buying the wrong size.
Buying separate pieces makes sense later on. For a second or third violin, like the Hora above, the violin comes alone, without accessories, and the bow and case are chosen more carefully, often together with the teacher. At full size, it's worth investing in these – they'll last for years, not just one growth stage.
What else you'll need alongside the violin
One detail that often worries parents unnecessarily: in many budget sets, the bridge comes lying flat in the case and the strings are loosened – this is for shipping protection, not a defect. The bridge is held in place only by string tension and needs to be set upright, with the feet aligned with the inner notches of the f-holes, before the first tuning; if you haven't done this before, ask the teacher at the first lesson – it takes two minutes. The teacher or parent will also tune the violin at first. The fine tuners on the tailpiece are for small daily adjustments, the tuning pegs for bigger changes.
Rosin is the basic consumable: without it, the bow hair slides over the strings with almost no sound. Many sets include it, and when it runs out, you'll find options in our rosin category. The second small purchase is a clip-on tuner, which attaches to the violin and senses vibration directly, so you can tune even in a noisy room; there are models designed for violin, like the D'Addario NS Micro. The shoulder rest usually comes up at the teacher's recommendation and is also size-specific, including versions for small violins, like the FOM for 1/4–1/16. And if the bow breaks – which does happen with kids – replacement bows are available for every size, so you don't need a new violin.
About strings, one number says it all: our best-selling product in the entire violin department isn't a violin, but a set of strings – Thomastik Superflexible 4/4, with 361 sets sold in a year. Strings break and wear out, so keeping a spare set in the case saves a missed lesson; just make sure they're the right size, from the categories above.

Frequently Asked Questions
Can I find the right violin size at home, without a teacher?
Yes, the measurement is simple. Have your child stretch their left arm out to the side, palm up, and measure from the base of the neck to the middle of the palm: 43–47 cm means 1/8, 47–51 cm is 1/4, 51–56 cm is 1/2, 56–60 cm is 3/4, and over 60 cm is full size. A teacher is still helpful for confirmation, but with this measurement you'll get the right size.
My child is between two sizes. Which should I choose?
The smaller one. A slightly smaller violin is comfortable to hold and can be played with proper technique, while one that's too big strains the arm, ruins intonation, and tires the child. The "grow into it" rule is the mistake we correct most often with customers.
Do you have 1/16 or 1/32 violins for very young children?
They're in our catalogue, but at these very small sizes stock fluctuates, and our shelf usually starts at 1/8. Check the product page for current availability or contact us before ordering. For three- to four-year-olds, we recommend choosing together with the teacher.
My child is left-handed. Do they need a left-handed violin?
Usually, no. Violin is almost always learned in the standard position, even by left-handed players: both hands have equally challenging roles, and bowing with the right hand is the norm in every class or orchestra. If the teacher recommends otherwise in a specific case, follow their advice.
How long will one size last?
Roughly, a year or two per size during the growth years, but it varies a lot from child to child. Repeat the arm measurement every few months: when they're clearly in the next range and the teacher agrees, it's time to move up. When you switch, check the strings, bow, and case too, as they're also size-specific.
Does violin size affect the sound?
Yes. A smaller violin has a smaller body, so less volume and depth, and that's normal – it's not a flaw. For children's sizes, the goal is correct posture and comfort, not concert tone. The "big" sound comes with full size and a better instrument.
