What Size Violin Do I Need? How to Measure a Violin

Measuring the correct size violin, viola, or cello is straightforward. If you haven’t already been advised which size you need, this short guide will help you choose the right instrument.
The difference in sizes may appear small — for example, a ¼ violin measures around 47cm, while a ½ size is only about 4cm longer — but even a small increase can make a noticeable difference to the player.
Using the wrong size instrument can cause the player to over-stretch or feel cramped. Either of these can make learning to play far more difficult and uncomfortable.
Most adults learning to play will usually need a full-size instrument, although it’s always worth checking if you’re unsure. For children, please follow the simple measurement steps below to find the most suitable size.
If you’re still uncertain after using this guide, please contact us. We’re always happy to help.
Just under the next size up?
If your child is only just below the measurement for the next size up, it can be tempting to choose the larger instrument.
However, it’s usually best to start with the smaller size and only move up once they are fully ready. Playing an instrument that is even slightly too large can restrict comfort and slow progress.
If the violin arrives and your child’s teacher recommends a different size, simply let us know and we’ll be happy to arrange a swap.

How To Measure

- Measurement 1 (neck to wrist) This indicates the most appropriate and comfortable size for the player.
- Measurement 2 (neck to palm) This indicates the largest size the player could use.
