Sizing Guide

Violin & Viola

Measure arm length, then read across for the size.

How to measure arm length

  1. Have the student extend their left arm straight out to the side.
  2. Measure from the base of the neck to the centre of the left palm.
  3. Use the measurement to find the correct instrument size.
Arm length Violin Viola Typical age
14″ to 15½″ 1/16 — 3–5 years
15½″ to 17″ 1/10 — 3–5 years
17″ to 18½″ 1/8 10″ 4–6 years
18½″ to 20½″ 1/4 11″ 5–7 years
20½″ to 22½″ 1/2 12″ 6–10 years
22½″ to 24″ 3/4 13″ 9–12 years
24″ and up 4/4 (Full) 14″ 12+ years

Violas also come in larger sizes (15″, 15½″, 16″) for advanced students and adults. These are typically chosen by players who have been going several years and know their preferred size by comfort and sound.

Sizing Guide

Cello & Bass

Measuring for cello

  1. Sit at the edge of a chair, knees bent at 90°, feet flat on the floor.
  2. Measure arm length from the base of the neck to the wrist.
  3. Measure the student’s height for reference.

The upper edge of the cello should rest in the centre of the chest (sternum), and the C peg should sit slightly behind the left ear. Knees should lightly grip the lower bouts, with the corners slightly above the inside of the knees.

Measuring for bass

  1. Measure the student’s height standing upright with good posture.
  2. When properly sized, the bridge sits at the height of the right-hand knuckles and the nut is near eye level.

Most adults play a 3/4 size bass — even professional orchestral players. It is better to choose a slightly smaller bass than one that is too large.

Student height Arm length Cello Bass Typical age
36–40″ 13–15″ 1/16 — 3–4 years
40–44″ 15–17″ 1/10 — 4–5 years
44–48″ 17–20″ 1/8 1/16 5–6 years
48–52″ 20–23″ 1/4 1/10 6–8 years
52–56″ 23–26″ 1/2 1/8 8–11 years
56–60″ 26–27″ 3/4 1/4 11–15 years
60–64″ 27″+ 7/8 1/2 15+ years
64″+ 27″+ 4/4 (Full) 3/4 Adult
