How do you know the correct size violin to buy?

The first step is to have the player stretch out his or her arm fully ensuring that there is no bend in the arm.

• The second step is to measure the total distance from the neck to the centre of the palm.

After following the above instructions, use the measurement and the sizing chart below to determine the proper violin size.

Cello sizing charts

When buying a cello or changing the size of a cello for a child it can seem tricky to know what size of cello you need, or what size you need to change to.

There are several methods to decide what size you need if your teacher hasn’t advised you. This chart gives you the size of the cello (measuring just the back of the cello, and the total length), and different criteria for what size is required as a general guide. All children vary, as do the cellos themselves.

There are cross over measurements which look confusing but if your child is a more petite build but reach other criteria, they will generally need the smaller size instrument, and vice versa.

Sizing a viola

How is a viola measured?

Viola sizes are defined by measuring the reverse side length from the side of the button to the centre line at the base. Violas of between 16 and 16½ inches (40.6 to 42cm) are classed as large-sized and suitable for most adults. Hidersine viola sizes are available in the standard and most commonly played sizes. These common sizes are generally suitable for the following age ranges based on the average size of a person at this age.
