Cello Size Chart
Complete cello sizing guide. Find the right cello size for your child with our age and measurement chart.
Cello size is set by height and arm length, not age alone. A child of 4'6" to 5' usually plays a 1/2 size, 5' to 5'6" a 3/4, and most people over 5'6" a full-size 4/4, which stands about 48 inches (4 feet) tall including the endpin. Use the chart below, then confirm with a teacher or rental shop.

Quick Answer:
Cello size is determined by arm length, similar to violin. Sizes range from 1/10 for very young children to 4/4 (full size) for teens and adults. Proper sizing is critical for technique and comfort.
How to Measure
Measure arm length from shoulder to fingertips with arm extended to the side. Also consider total height. When seated with cello, the top of the body should reach the upper chest.
Tips
- Cello requires more space than violin - consider home practice area
- Renting is highly recommended as children grow through sizes
- Transport requires a vehicle that can fit the cello
- A properly sized cello prevents injury and builds good technique

Frequently Asked Questions
How tall is a cello?
A full-size (4/4) cello is about 48 inches (4 feet) tall from the floor to the top of the scroll, with the endpin set for a player of average height. Smaller fractional cellos are shorter, roughly stepping down 2 to 4 inches per size, and makers vary by an inch or two.
How big is a cello compared with a violin?
A full-size cello is about 48 inches tall and a full-size violin body is about 14 inches long, so a cello is roughly three times the length. A cello stands on the floor on an endpin and is played seated, which is why it needs a car with enough room to carry it.
How long is a cello?
The body of a full-size cello is about 30 inches long, and the whole instrument is about 48 inches from the endpin to the scroll. A 1/2 size is shorter, roughly 41 to 42 inches overall, and a 1/4 size is around 36 inches, with some variation by maker.
What are the cello sizes?
Common cello sizes are 1/10, 1/8, 1/4, 1/2, 3/4 and 4/4 (full). A 7/8 size also exists for adults with smaller hands. The size is chosen by height and arm length, and ages are only a rough guide.
What size cello for a 6 year old?
Most 6-year-olds use 1/4 size cello. Smaller children may need 1/8 size. Have your child measured by a teacher or music store for accuracy.
How do I transport a cello?
Cellos require a vehicle with enough space - usually a sedan with fold-down seats, wagon, SUV, or minivan. Hard cases protect during transport.
Should I rent or buy a cello?
Renting is strongly recommended for children due to frequent size changes. Cello rentals typically include maintenance and size exchanges.
