Some children are exceptions to the rule, but this chart provides a general age range for these instruments.
As a teacher I have worked with 10-year-olds who played full size violins. The most important thing in deciding the correct size is that the student can comfortably play the instrument in tune. Fourth finger, or pinky, reach and intonation (can it be played in tune?) may be the deciding factor.
Rory, the lovely Fiddleheads student pictured at the left at age 12, played a full size starting on her 10th birthday! It looked a bit big, but she could play it in tune and truly appreciated the bigger sound the full size produced. She grew into it over the summer and her parents were glad they didn't buy a 3/4 or else she would have outgrown it in a few months. A
To accurately discern which size is correct for the player, run a measuring tape from the left side of the player's neck to palm of their outstretched left arm and second time from the neck to the wrist. (The arm must not be bent at the elbow and is at a right angle to the body. Palm faces up at the ceiling)
Violists: measure from neck to palm at the base of the fingers, not the wrist. Violas are sized large.
Check the measurements on the violin chart above:
PALM: The neck to palm measurement indicates the largest size that would be appropriate. Only go larger than this size if the child is growing rather quickly and if you are certain the teacher will not object to the large violin.
WRIST: The neck to wrist measurement provides a comfortable size. Suzuki teachers in particular are trained to teach players on a violin fitting this way (not too large).
As stated in point 1, the most important thing in playing a large-ish instrument is that the player can comfortably play in tune. (again, 4th finger intonation may be the deciding factor).
Please note that even left-handed players play a regular, right-handed violin. Lefties need not worry they can't play the violin! I have taught many lefties and they play the same as everyone else.
Violins are either "full size" or "fractional. Adults, teens and children age 10-12 play full size. Children play 3/4 and smaller violins depending on their size. The bow used matches the size of the instrument. For example, a 3/4 violin is paired with a 3/4 size violin bow.
*Note that Violas are not sized like violins in fractions, rather they are measured by the length of their bodies in inches. For example, a typical sized viola for a student age 12 has a body 15.5" in length and the same sizing rules do not apply as violas are expected to fit a bit big.
**Viola bows are only available in "full" size. Violists seeking fractional sized bows simply use a violin bow. For example, a 14" viola player would use a 4/4 violin bow, a 13" viola player would use a 3/4 size violin bow.
4. Violin Measurements (Length- Body/Total)These measurements vary from maker to maker by as much as 3/4". If you are unsure which sized instrument you have, carefully take two measurements with a tape or string. Violas only require one measurement; the body (measurement #2).
1. Measure first the violin the length of the violin from the top of the scroll to the bottom (excluding the end pin at the bottom).
2. Next measure the body from the "shoulders" of the violin to the bottom. Do not include the jutting-out section at the base of the violin's neck in your measurements.
*Note that the width of the violin (measuring the upper or lower "bout") varies widely from maker to maker or style to style. Instruments made in the style of Guarneri tend to have wider lower bouts than Strad models, and thus a bigger volume and depth of tone.
As a teacher I encounter this dilemma frequently and make the decision to skip a size on a case by case basis.
Choosing to use a larger violin can be a wise choice if the student is growing rapidly and if you are paying a bit more to have a better quality, larger violin rather than buying an intermediate violin and replacing it soon after. Rather than buying two cheaper violins one after another, the larger violin would be used longer, thus it would make sense to invest a bit more money into it.
The important thing here is that the student is able to or very close to playing the 4th finger. If they can reach this fingering the violin will be usable.
For children skipping a size and playing a slightly large violin you should carefully consider playing a lighter weight violin over a heavy one. Heavier or bulkier violins can be harder to hold up, overextended for long periods of time causing the student to not want to practice for long. A student who has quit never saves the parents money on the violin purchase!
Another suggestion here is to use a shoulder rest to aid in holding a violin which is too large and needs more support.
