Instrument Fitting

Which size Instrument do I need?

Violins and cellos are available in full size (4/4) which is suitable for most secondary school children and adults right down to 1/16 (for pre schoolers). Most infant children in our experience will need a 1/8-1/4 size instrument with juniors moving up to ½-3/4 size. Children don’t come in standard sizes though so please refer to our useful size charts page for guidance. Viola sizing is a little different as they come in “inches” rather than “sizes” the largest tending to be 16 ½ “ down to 15” although smaller sizes are readily available for children.

We realise that not everyone has access to an instrument to check the size before they buy so here are some tips to help you get it right:

  • Be guided by what your teacher says, they will probably know which size your child needs.
  • Avoid buying an instrument that is too big so your child can grow in to it as it will feel heavy and cumbersome to play. This can slow down any musical progress.

Here is an alternative way of measuring for a new violin or viola:

Extend left arm out towards the front with no bend at the elbow or wrist (don’t over extend your elbow)
Measure from:

  1. The base of the neck to the centre of the palm
  2. The base of the neck to the wrist (where the skin creases)
  3. Now use your measurements to select the correct size instrument using either the violin or viola charts below.

Measurement 1. Shows the largest size violin that your child could manage.
Measurement 2. Shows the most comfortable/suitable size.

Fitting a violin:

  1. Put the violin on your left shoulder (as if you are about to play it)
  2. Extend your left arm and reach your fingers around the end of the scroll (the curly bit at the very end)
  3. Your left elbow should be slightly bent (not more than 90 degrees)

Fitting a cello:

  2. The “C” tuning peg should be near to your left ear
  3. The sides of your knees should be touching the lower curved edges of the cello
  4. The back of the cello should rest on your chest (breast bone or sternum)
