A kids' guitar is on the wish list, but which size fits which age? The question that comes up most often is about the 3/4 guitar — what age is it for, and when does a child outgrow it? This guide sorts the four common guitar sizes — 1/4, 1/2, 3/4, and full size (4/4) — by age, height, and scale length, and names matching starter models for each step.
A quick note: of the four kids' guitar sizes, the 3/4 covers the longest age window — from early primary school through the move to secondary school (see the table below). Even so, it helps to know the exact ranges, because a guitar that's too big slows down learning more than one that's slightly too small.
01The four guitar sizes at a glance
The table below gives guideline values. Arm length and hand size vary from child to child, and the transitions between sizes are gradual. When in doubt, pick a size with a bit of room to grow rather than one that's already tight at purchase.
| Size | Age | Height | Scale length |
|---|---|---|---|
| 1/4 | approx. 4–6 years | up to approx. 110 cm | 48 cm |
| 1/2 | approx. 6–8 years | approx. 110–130 cm | 56 cm |
| 3/4 | approx. 8–11 years | approx. 130–145 cm | 58 cm |
| 4/4 | from approx. 11–12 years | from approx. 145 cm | 65 cm |
02Why the 3/4 guitar is so often the right choice
A 3/4 guitar isn't a scaled-down toy with fewer options — it's a full classical concert guitar with six strings in standard tuning, just with a shorter scale length and a narrower neck. Children learn exactly the same chord shapes and fingerings on it as on a full-size guitar, just with less reach for the hand.
Prodipe Primera 3/4 Kurzmensur Konzertgitarre Fichte shows what that looks like in practice: solid spruce top, mahogany back and sides, bone nut and saddle instead of plastic, plus a carbon-reinforced neck against warping — details rarely found on a pure entry-level model.
03Checking the size at home
Two simple checks help without a tape measure:
1. Measure your child's height and compare it with the table above — the most reliable first step. 2. The elbow test: the child holds the guitar as if playing. The strumming arm should comfortably wrap around the body without raising the shoulder. If that isn't the case, the guitar is too big.
04One series, four sizes: the Prodipe Primera
For families with children of different ages, or planning ahead for the next size change: Prodipe's Primera series comes in all four sizes at the same entry price — same spruce top, same mahogany body, same carbon-reinforced neck, only the scale length grows.
For the smallest players: Prodipe Primera 1/4 Kurzmensur Konzertgitarre Fichte, 48 cm scale length, narrow 45 mm nut width.
For the start of primary school: Prodipe Primera 1/2 Kurzmensur Konzertgitarre Fichte, 56 cm scale length.
For the primary-school stretch with the longest age window: Prodipe Primera 3/4 Kurzmensur Konzertgitarre Fichte, 58 cm scale length.
For teenagers and adults: Prodipe Primera Konzertgitarre 4/4 Fichte, classic full scale length.
05From 3/4 to full size: when to switch
Height is the most reliable signal: once it reaches the next bracket in the table, the sound usually becomes cleaner too, because bigger hands fret more precisely. A growth spurt mid-school-year is normal — a 3/4 guitar usually stays playable for several more months before a switch to full size makes sense. There's no fixed expiry date, only the match between height and scale length.
06Browse the right size
Prefer to filter yourself? Konzertgitarren 3/4 shows the full 3/4 range, sortable by brand, wood, and price. The other sizes are under Konzertgitarren 1/4, Konzertgitarren 1/2, and Konzertgitarren 4/4.
Height is the most reliable guide, age only a rough orientation. Combine the table above with the elbow test and the choice is almost always right — and with the Primera series, every one of the four sizes has a matching entry model at the same price.
