waiyean:How long does a 1/2 size violin last? My girl's 1/4 size violin lasted for 1.5 years, and now it's time to upgrade to the next size. What comes after 1/2 size... 3/4? Do most students go to 3/4 or do they go full size directly?
Just sharing from personal point of view, I think its advisable that kids should only play violins of the right size. From experience, using an oversized or undersized (not as much but will affect intonation) violin, increases the risk of negatively affecting their posture, left hand shape, muscle development. It can affect the development of their vibrato since the fingerboard will be thicker in a bigger violin. For the players who are playing intermediate to advanced repertoire at a younger age especially, it can restrict their \"free-ness\" and ability to vibrate well in high positions unless they have big hands and long fingers.
The rate of upsizing depends on the growth rate of the child and can differ from year to year. I have seen younger kids than mine upsizing much faster and playing bigger instrument. My boy plays 1/2 size for almost 3 years till he is p3. Even within a particular size, the violin sizes come in a range, use the violin back and overall lengths to gauge. There are bigger 1/2 and smaller 1/2, same goes for all other sizes.
Also don't forget the bow. It should be of the right size too and my personal view is that it don't necessarily have to follow the upsizing rate of the violin. I think playing an oversized bow is undesirable for a proper bow hold and bow control. Playing bow that is not of the right balance can place too much pressure on their developing arms and fingers. The balance of the bow and the weight it felt to the child is important. Perhaps can try changing violin and then eventually bow.
