The violin is generally smaller, with an average body length of about 14 inches (35.5 cm), while the viola is larger, typically ranging from 15 to 18 inches (38 to 45 cm). This size difference affects not only the instrument’s weight but also the spacing of the strings and the overall feel when played.

The violin is a bit smaller than the viola. A typical full-size violin is about 36 cm (14 inches) while a full-size viola is around 40 cm (about 16 inches). Even though this size might vary, it is no smaller than 38cm. Therefore, it is still bigger than the violin. Also, the body of the instrument is wider and deeper.

The violin is smaller than the viola, sometimes by up to 25%. The size difference is proportional, so the viola is longer, wider and taller than a violin with a longer neck and larger fixings.
