Viola Size Guide

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

Teacher Recommendation:

The first step when finding out which viola size you will need is to check with a music teacher. Most of the time a teacher will measure the pupil and note which viola size is required. You should always go with the size recommended by the teacher. However, if you do not have a teacher recommended size read on to find out how to get the size yourself.


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

Arm Length:

Measuring the arm of the player is one of the most simple and accurate ways of determining which size viola 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 from the neck to the base of the fingers. Once you have your measurement use our table below to find which size viola will be best.

20" 12" 6-7
21.5"-22" 13" 7-9
23"-24" 14" 9-12
24.5" 15" 10-12/Small Adult
25" - 25.5" 15.5" 12+/Average Sized Adult
26"+ 16" Full Size Larger Adult

It is worth bearing in mind that violas are larger than violins and are on the larger size for the player. However, the viola should not be so large that is causes discomfort for the player, if this is the case we recommend sizing down.
