3/4 Size vs Full Size Guitar for a Child
Should a child start on a 3/4 or full size guitar? Size is decided by whether they can reach comfortably, and a guitar that is too big stops progress.
Quick Answer:
Buy the size the child can actually hold. A three quarter guitar suits most children from roughly eight to eleven, and a full size suits most from about eleven or twelve upward depending on their build. A guitar that is too large makes chord shapes physically impossible and is one of the most common reasons a child stops. Buying big so they can grow into it does not work.
| Factor | 3/4 Size Guitar | Full Size Guitar |
|---|---|---|
| Typical age range | Roughly 8 to 11 | Roughly 11 and up |
| Scale length | Shorter, easier reach | Standard |
| String tension | Lower, easier on fingers * | Higher |
| Volume and tone | Smaller, thinner | Fuller * |
| Growing into it | Will be outgrown | Lasts into adulthood * |
| Chord shapes reachable | Yes for small hands * | Difficult for small hands |
| Resale | Reasonable, steady demand | Strong * |
| Typical price | Around 180 dollars * | Around 230 to 260 dollars |
* Indicates better option for that factor
How to tell which size fits
Sit the child down with the guitar on their right leg in the normal playing position. Their strumming arm should come over the body without their shoulder hunching, and their fretting hand should reach the first fret without stretching the arm straight. If either is a struggle, the guitar is too big. This takes thirty seconds in a shop and it is worth doing before ordering online, even if you then buy the same model elsewhere.
Why buying big does not work
The reasoning is understandable and the outcome is predictable. A child who cannot reach a chord shape concludes that they cannot play, not that the guitar is wrong, and that conclusion ends far more musical childhoods than lack of talent does. A smaller guitar that is outgrown in two years has done its job if the child is still playing at the end of them, and three quarter guitars hold their value reasonably well second hand.
What a shorter scale actually changes
Scale length is the distance from the nut to the bridge, and a shorter one means the frets are closer together and the strings are at lower tension for the same pitch. Both of those help a beginner: less stretch between fingers, and less force needed to press a string down. Lower tension also means less finger pain in the first weeks, which is when most people quit.
Where a smaller guitar loses out
A smaller body moves less air, so a three quarter guitar is quieter with a thinner sound, and it will never sound like a dreadnought. For a child learning chords in a bedroom that does not matter at all. It starts to matter when they play with other people or want to record, which is generally around the point they have outgrown it anyway.
Our Verdict
Choose the size that fits today. For most children under about eleven that is a three quarter guitar, and a full size guitar bought early is a common and avoidable reason children stop playing. If the child is close to the boundary, sit them down with both and let the reach decide it rather than the price or the expected growth.

Frequently Asked Questions
What about half size guitars?
Half and quarter size guitars exist for very young children, roughly five to eight, and they are genuinely small instruments with a thin sound. They can work for a young starter, and be aware that very cheap small guitars are often poorly made and hard to keep in tune, which frustrates a child faster than size does. Buy a small guitar from a reputable maker rather than the cheapest available.
Will a child outgrow a 3/4 guitar quickly?
Usually within two to four years, depending on when they start and how they grow. That is a normal part of learning an instrument as a child and it is the same pattern as violins, which are sized in far more steps. If cost is a concern, second hand three quarter guitars are widely available and hold up well, since they see gentle use.
Do adults ever use 3/4 guitars?
Some do, particularly travellers and people with smaller hands, and short scale guitars have a following among adults for comfort rather than compromise. If an adult beginner finds a full size dreadnought uncomfortable, a smaller body is a completely legitimate choice rather than a step down.
