One of the most common concerns parents have when their child begins playing a string instrument is growth. Children grow quickly, sometimes seemingly overnight, and parents naturally worry about whether the instrument their child is using is still the right size. The good news is that needing a larger instrument is normal, expected, and easily managed when renting from Northland Violins.
Understanding how often students typically move up in size, what signs to watch for, and when to have an instrument checked can help parents feel confident that their child is always playing on an instrument that supports healthy technique and musical progress.
Why Instrument Size Matters
String instruments are not one-size-fits-all, especially for children. Violins, violas, cellos, and basses all come in multiple fractional sizes designed to match a student’s height, arm length, and hand size.
An instrument that is too small can feel cramped and limit reach. One that is too large can cause tension, poor posture, and even discomfort or injury. Proper sizing allows the student to play comfortably, develop correct technique, and focus on learning music rather than struggling physically.
At Northland Violins, proper sizing is always done in person, with the student present. Measuring ensures the instrument fits the student as they are now, not based on guesswork or age alone.
How Often Do Students Typically Change Sizes?
There is no fixed schedule for moving up instrument sizes because children grow at different rates. However, some general patterns are common.
Younger students, especially those in elementary school, tend to change sizes more frequently. Growth can happen quickly at this stage, and it is not unusual for a student to need a larger instrument every 12 to 18 months. In some cases, particularly during growth spurts, changes may happen even sooner.
As students get older and move into larger fractional sizes, the time between size changes usually increases. Once a student reaches a full-size instrument, typically around late middle school or early high school depending on the instrument and the child, sizing changes stop altogether.
Differences Between Instruments
While the concept of sizing applies to all orchestral string instruments, the pace can feel slightly different depending on the instrument.
Violins and violas have several fractional sizes, so students often move through multiple steps as they grow. Because these instruments are smaller, even small changes in arm length can signal that it is time to check sizing.
Cellos also come in fractional sizes, and younger students may move up as they grow taller. However, because cellos are played seated and supported by the endpin, students sometimes remain comfortable in a size longer than violinists or violists.
Double basses are larger instruments, but they also come in smaller sizes suitable for young players. Growth changes still apply, and students should be checked regularly to ensure the instrument remains appropriate.
Regardless of instrument, the guiding principle is the same: if the student looks uncomfortable or strained, it is time for a sizing check.
Signs It May Be Time to Move Up a Size
Parents often notice subtle clues before a size change becomes obvious. These can include the student struggling to reach notes comfortably, holding the instrument at an awkward angle, or appearing tense while playing.
Teachers may also mention that the student’s posture looks off or that technique is becoming harder than it should be. These comments are often early indicators that the instrument is no longer the right fit.
If there is any doubt, the best course of action is to bring the student into Northland Violins or Von’s Violin Shop for a sizing check. There is no downside to checking, and many times the result is simply reassurance that the current size is still correct.
When to Expect Size Changes During the Year
While growth can happen at any time, the start of the school year is a particularly common moment for size changes. Over the summer, children often grow taller and stronger, and parents are already adjusting clothing, shoes, and school supplies.
This makes late summer and early fall an ideal time to have an instrument checked. It aligns naturally with back-to-school routines and ensures the student begins the year with an instrument that fits properly.
That said, parents should not wait for a specific season if concerns arise. Northland Violins encourages families to come in whenever they are unsure.
How Rentals Make Size Changes Easy
One of the biggest advantages of renting from Northland Violins is that moving up to a larger size instrument is part of the rental program. There is no additional charge to exchange a rented instrument for the next appropriate size.
This removes a major source of stress for parents. Instead of worrying about buying and reselling instruments or predicting future growth, families can simply focus on the student’s needs at each stage.
When a size change is needed, the process is straightforward. Bring the student in, have them measured, and exchange the instrument. The goal is always to keep the student playing comfortably and confidently.
The Importance of In-Person Sizing
While age charts and online guides can provide rough estimates, they are not substitutes for in-person sizing. Children of the same age can vary widely in height, arm length, and build.
At Northland Violins, sizing is done by experienced staff who work with students every day. This hands-on approach ensures the instrument truly fits the student and supports proper playing habits.
Parents should always bring the student with them when addressing sizing questions. An instrument cannot be sized accurately without the student being there.
