Violin Size Guide

If you are buying a violin from Duet Shop, for either yourself or your child, you will want to make sure you choose the right size violin. We have put together a simple guide to help.


Whilst there will be some exceptions to the rule, age is usually a great indicator for the size of violin required. In the table below you will find the size of violin recommended for the age of the player. However, to ensure you get the best size violin we do also recommend that you measure the arm of the player.

Arm Length:

Measuring the arm of the player is the most accurate way of determining the size of the violin you will need.

This is easily done by extending the left arm at a right angle from the body and measuring, with a yard stick or measuring tape, the distance between the neck and the centre of the palm.

When you have the right size violin you should be able to comfortably curl your fingers around the end of the violin (the scroll).

Once you have your measurement use our table below to find which size violin will be best for you.

14"-15" 1/16 3-5
15"-16" 1/10 4-5
16.5"-18" 1/8 5-6
18"-20" 1/4 6-7
20"-21.5" 1/2 7-9
21.5"-22" 3/4 9-11
23"+ 4/4 Full Size 12+

Bow Size

Alongside having the correct size violin you want to make sure that you also have the correct size bow. This is pretty simple just make sure to choose the same size bow as your violin i.e. if you need a 3/4 violin you will need a 3/4 bow. However, don't worry about this too much as all the violins available from Duet Shop come with the correct size bow and case!

Still Unsure?

You may find that yourself of your child sit between sizes and you are unsure on whether to size up or down. In most cases you will be able to size up, especially if you have a growing child, but we do have a few helpful hints that may make making the decision a little easier.

  • Check with the music teacher. A music teacher will be able let you know if they think you should size up or down.
  • If when holding the violin the elbow is straight or the player cannot reach the end of the violin (the scroll) then the violin is too big and you would be better to size down.
  • If when holding the violin the player can very easily reach the end of the violin and the elbow is bent at less than a 90 degree angle then the violin is too small and you will be better to size up.
  • The most important factor in choosing the size is that the violin should feel comfortable and be able to be played in tune.
  • Don't worry if you have a growing child and are scared that they will quickly grow out of their violin, with Duet Shop all our instruments can be returned after 4 months. So rather than get a violin that is too big, you can get the size you need now and then return that violin for the next size up when the time comes.
