How to Accurately Measure the Body Size of Violins, Violas, Cellos, and Upright Basses

Introduction

Measuring the body size of string instruments is crucial for musicians, whether they are beginners or seasoned professionals. Each instrument, from the delicate violin to the robust upright bass, possesses unique dimensions that affect playability, sound quality, and overall comfort. In this comprehensive guide, we will explore the best practices for measuring the body size of violins, fiddles, violas, cellos, and upright basses, ensuring you have all the knowledge needed to make informed decisions.

Understanding the Dimensions of String Instruments

Before diving into the measurement process, it's essential to understand the key dimensions that define string instruments:

These dimensions vary significantly between different types of string instruments and can influence a player's experience and sound production. Understanding how to measure these dimensions accurately is imperative.

Measuring Violins and Fiddles

To measure a violin or fiddle accurately, follow these steps:

  1. Gather Your Tools: You will need a soft measuring tape or ruler, a pencil, and paper to note your measurements.
  2. Measure Body Length: Place the measuring tape from the top of the scroll to the bottom of the body. Record the measurement.
  3. Measure Body Width: Measure the width at the widest points of the upper and lower bouts. Average these two measurements for a more accurate representation.
  4. Measure Body Depth: Measure the thickness of the instrument at the center of the body. This is usually done at the ribs.
  5. Measure Scale Length: Start at the nut and end at the bridge. This measurement is crucial for string tension and playability.

For example, a standard violin typically has a body length of about 14 inches, while the width ranges from 6.5 to 8 inches.

Measuring Violas

Violas have a larger body compared to violins, and measuring them involves similar steps with some variations:

  1. Gather the same tools: a soft measuring tape or ruler.
  2. Measure the body length, which typically ranges from 15 to 18 inches.
  3. Measure the body width at the upper and lower bouts, recording both measurements.
  4. Body depth measurement remains the same as violins.
  5. Measure scale length from nut to bridge, keeping in mind that it is longer than violins.

For example, a standard viola may have a body length of about 16.5 inches and a width of 8.5 inches.

Measuring Cellos

Cellos are significantly larger instruments, and their measurements are as follows:

  1. Use the same measuring tools.
  2. Measure the body length, which typically ranges from 24 to 27 inches.
  3. Measure the body width across the upper and lower bouts, averaging them for accuracy.
  4. Body depth should be measured at the ribs, similar to violins and violas.
  5. Measure the scale length, which is typically around 27 inches.

For example, a standard cello usually has a body length of about 25 inches.

Measuring Upright Basses

Measuring an upright bass is a bit different due to its size and shape:

  1. Prepare your measuring tools.
  2. Measure the body length, which typically ranges from 40 to 45 inches.
  3. Measure the width across the bouts, noting that the lower bout is the widest.
  4. Body depth should be measured at the ribs as well.
  5. Measure scale length, which is crucial for determining string tension.

The average upright bass body length is approximately 41 inches.

Tips for Accurate Measurements

Here are some tips to ensure your measurements are precise:

Case Studies

In this section, we will examine a few cases where accurate measurements made a significant difference:

Case Study 1: Beginner Violinist

Emma, a 10-year-old beginner violinist, was struggling with her instrument due to size mismatch. After measuring her body size and the violin’s dimensions, her instructor recommended a smaller 1/8 size violin, which improved her comfort and playability.

Case Study 2: Professional Cellist

John, a professional cellist, had always played a full-size cello. However, after measuring his physical dimensions and considering his playing style, he realized a slightly smaller instrument could enhance his technique. Transitioning to a 7/8 cello allowed him better control over his performances.

FAQs

1. How do I know what size instrument I need?

The best way to determine the right size is to measure your body dimensions and compare them with the standard measurements of string instruments. Consult with a music teacher or instrument retailer for personalized advice.

2. Can I measure my instrument alone?

Yes, you can measure your instrument alone, but having a friend assist you can help ensure more accurate readings.

3. What if my measurements fall between sizes?

If your measurements are between sizes, it's generally recommended to try both sizes to see which one feels more comfortable and allows for better playability.

4. How often should I check my instrument size?

It’s advisable to check your instrument size annually, especially for growing children or if you are considering a change in your instrument.

5. Does the type of strings affect size measurement?

No, the type of strings does not affect size measurement, but it can affect the overall sound and playability of the instrument.

6. Can I use a ruler instead of a measuring tape?

While a ruler can be used, a soft measuring tape is recommended for more accurate curves and contours.

7. Are there specific brands that are better for certain sizes?

Yes, different brands may have varying size specifications, so it's best to research and consult with experts when selecting an instrument.

8. What should I do if my instrument is damaged during measurement?

Always take care when measuring. If damage occurs, consult a professional luthier for repairs.

9. How do environmental factors affect instrument size?

Humidity and temperature can affect the wood of string instruments, potentially leading to slight changes in dimensions over time.

10. Where can I find professional measuring services?

Local music stores, luthiers, or music schools often provide measuring services for string instruments.

Conclusion

Measuring the body size of string instruments is crucial for ensuring comfort and optimal performance. By following the step-by-step guides outlined in this article, you can accurately determine the dimensions of violins, violas, cellos, and upright basses. Always remember that a well-fitted instrument can make a significant difference in playability and sound quality, leading to a more enjoyable musical experience.
