The viola is often treated as “a slightly larger violin,” but choosing one follows quite different logic — especially when it comes to size. Here is what to look at when selecting a viola.

Size: The Most Important Step

Unlike the violin, which has a standard full size (4/4), the viola has no single “standard adult size.” Violas are measured by body length in inches, commonly ranging from 14 to 16.5 inches.

The right size depends on your build, not your age: arm length, hand size, and shoulder width all matter. As a rough guide, extend your left arm and measure from the side of your neck to the middle of your palm — that distance helps point to a suitable body length.

The key principle: when in doubt, size down rather than up. A viola that is too large forces the left hand into constant overreach, inviting strain over time, and can be hard to control. Most adults land around 15.5–16 inches; smaller players and teens use 14–15 inches; those with long arms and large hands may reach 16–16.5 inches. Ultimately, let comfort decide — the instrument should feel easy to hold and play, never a stretch.

Sound and Pattern

A viola is larger than a violin and tuned a fifth lower (C–G–D–A), giving it a warmer, deeper voice weighted toward the lower-mid range.

At the same size, different patterns favor different tone. The Tertis pattern — a larger body popularized by the English violist Lionel Tertis — tends toward fuller volume, while traditional patterns such as the Stradivari are more balanced. Try several and choose the tonal character that suits you.

Grade and Budget

  • Student grade: suited to beginners and exams, on a modest budget.
  • Intermediate grade: upgraded workmanship and tonewood, with a more open sound and better response, for players with some foundation.
  • Advanced / handcrafted: fully handcrafted with fine tonewood, mature in tone and finish, for advanced and professional players.

The principle: within a properly fitting size, choose a grade that meets your current level with a little room to grow — there is no need to jump straight to the highest tier.

Workmanship and Trying It Out

  • Look at: the grain of the top and back, the evenness of the varnish, the feel of the neck, and the fittings (ebony fingerboard, bridge).
  • Play-test: whether all four strings are balanced in volume, whether the upper positions stay clear, whether the instrument sits comfortably, and whether it tires you over a long session.
  • If you can, bring a teacher or luthier along to try it with you.

In Short

When choosing a viola, fit always comes first, then tone, then grade. Measuring carefully and trying several instruments usually matters more than worrying about brand.
