Concert vs Tenor Ukulele: What the Extra Two Inches Actually Change

A concert ukulele has a scale length of about 15 inches and is roughly 24 inches of instrument. A tenor is 17 inches of scale and about 26 inches overall. The tuning is the same, the chord shapes are the same, both carry eighteen frets, and at the two makers who build the identical instrument in both sizes the price is the same or within twenty dollars.

Córdoba and Kala both publish full dimensions for their own matched pairs, which makes this an unusually settleable argument. Two things genuinely change between the sizes: the frets move about 15 percent further apart, and the body gets roughly half again as big. Almost everything else that gets listed as a difference — the neck, the fret count, the nut width, the price — does not reliably change at all.

Side by side

Two and a quarter inches of scale, and where they go

Córdoba’s concert scale is 375mm — 14¾ inches — and their tenor is 432mm, or 17. Kala publishes 14.875 and 16.968 for the same two sizes. Since both instruments lay eighteen frets over that scale, every fret on the tenor sits about 15 percent further from its neighbor. Over the first five frets, where beginners spend all their time, that adds a little over half an inch of room for the fretting hand.

Half an inch spread across five frets sounds like nothing and is not. It is roughly the difference between a fingertip landing cleanly behind a fret and landing on top of it, which is the single most common reason an adult beginner’s chords buzz. If you have already tried a soprano or a concert and found your fingers crowding each other, the tenor is the specific fix for that problem, and no amount of practice on a smaller instrument replaces it.

What the extra scale does not buy you is more instrument to play. Both sizes carry eighteen frets and both join the body at the fourteenth, so the tenor gives you the same notes with more space between them. It also does not make the neck bigger in your hand: Córdoba’s neck is 17mm thick at the first fret and 20mm at the ninth on the soprano, the concert and the tenor alike. The hand that wraps around the back cannot tell the sizes apart.

The concert is a soprano with a longer neck. The tenor is a bigger box

Kala publishes every dimension of the KA-15 range, and read across the four sizes it says something the size charts do not. Their soprano and their concert have the same body depth — 2.367 inches, to the thousandth. The concert’s body is an inch and a quarter wider across the lower bout and half an inch longer, but front to back it is a soprano. Almost all of the three extra inches of instrument is neck.

The tenor is where the box changes. It is 3.121 inches deep — a third more than either of the smaller sizes — an inch wider across the lower bout at 9¼, and a little over half an inch longer in the body. Multiply those three together and the tenor is holding roughly half again as much air as the concert.

That is the honest explanation for the difference in voice, and it is a better one than scale length. A bigger, deeper box resonates lower and holds a note longer, which is why a tenor sounds warm and sustained where a concert sounds bright and quick. It is also why the step from soprano to concert changes the feel far more than the sound, while the step from concert to tenor changes both.

A third more tension, and what it does to the sound

Longer strings at the same pitch have to be pulled tighter, and D’Addario publishes the figures for its own sets. Their standard nylon concert set totals about 33 pounds across the four strings; the tenor version of the same set totals about 44. The gauges are within a thousandth or two of each other, so nearly all of that third is the scale length doing it.

Forty-four pounds is still a very small number — a mandolin pulls about 180 — so this is not a difficulty you will notice in your fingertips. What you notice is response. A tighter string is harder to push out of tune when you fret it, holds pitch better when you strum hard, and drives the top with more force, which is where the tenor’s extra volume and sustain actually come from. It is also why a tenor rewards fingerstyle playing: the notes hang around long enough to overlap into something like a melody with an accompaniment underneath.

The concert’s lower tension gives up sustain and gets back the bright, quick, percussive attack that most people mean when they picture a ukulele. Strummed under a voice in a room full of people, that is arguably the more useful sound. Neither is better; they are pointed at different jobs.

A tenor does not automatically give you a wider neck

String spacing is a separate specification from fret spacing, and only one of the two comes with the size. Fret spacing runs along the neck and follows the scale length, so it is fixed the moment you choose concert or tenor. Nut width runs across the neck and follows nothing at all — the maker picks a number, model by model.

Both makers prove it inside their own catalogues. Kala’s published figure is 1.39 inches at the nut on the concert and 1.39 inches on the tenor — the same number, and only sixteen thousandths of an inch more than their soprano. Buying the bigger Kala buys you no extra string room whatsoever. Córdoba is less consistent rather than more helpful: their 15TM tenor is 38mm, a genuinely roomy inch and a half, while their 20TM — a better instrument in every other respect, at around $200 — is back to 35mm, exactly what both of their concerts measure and exactly what their soprano measures too. Spend more inside that range and the string spacing gets narrower.

So if the problem you are solving is fingers muting the string next door rather than fingers crowding the frets, the size on the label will not tell you whether you have solved it. Look up the nut width for the specific model. Where it is not published, assume 1⅜ inches, because that is the default across almost everything under $200 in both sizes. Our guide to tenor ukuleles lists the figure for each pick, and it does not rise with price.

Low G is the one thing only a tenor does properly

Standard ukulele tuning is gCEA, and the lower-case g is doing real work: it means the fourth string is tuned above the third rather than below it. That is called re-entrant tuning, it is why a strummed ukulele chord sounds like a chime rather than a guitar, and it means the instrument has no bass note at all. Written with a capital G, GCEA, the fourth string drops an octave and the instrument becomes linear — chords get a root underneath them and melody lines stop falling off the bottom of the neck. It takes a specific wound string; you cannot get there by slackening the one already fitted.

Both sizes are sold in gCEA and both take the same chord shapes, so nothing about the tuning separates them on paper. What separates them is that a low G needs scale length behind it to speak. On a concert it tends to sound slack and thuddy; on a tenor’s 17 inches it rings. The makers say so with their catalogues rather than their marketing: D’Addario’s ukulele range runs to more than twenty sets, and exactly two of them are low-G. Both are tenor sets. There is no concert low-G set in the line.

If solo fingerstyle arrangements or jazz are what you are picturing, that settles the size question on its own, and it is worth budgeting the thirteen dollars for the strings at the same time as the instrument — almost every tenor ships in high G, so the thing the size is best at is not what comes out of the box. Our ukulele strings guide covers the materials.

The size is not what you are paying for

A tenor uses more wood than a concert, so it ought to cost more. Against the two makers who sell the identical instrument in both sizes, it barely does. Córdoba’s 15CM concert and 15TM tenor carry the same price, around $130 each. Their solid-top pair, the 20CM and the 20TM, are ten dollars apart at around $200. Kala’s own list prices for the KA-15 series step from $89 for the concert to $109 for the tenor, and their bundled versions with a bag and tuner land at about $115 whichever size you pick.

That last figure is the one worth acting on. The concert bundle costs about thirty dollars more than the bare concert; the tenor bundle costs about six dollars more than the bare tenor. If you want the gig bag, the strap and the tuner — and a first ukulele needs all three — the tenor is where that package is close to free.

Where the money genuinely changes the instrument is construction, not size. Everything under about $150 in both sizes is laminate mahogany — thin plies under a veneer, which is tough, ignores humidity and will sound the same in ten years as it does this afternoon. Córdoba reserve the word solid for their 20 series, where a solid top arrives at around $200 and is the first upgrade that changes the sound rather than the specification. Our tonewood guide goes through what each species contributes once construction is settled.

The four to buy

Which one, in one line each

• Adult, first ukulele, no strong feelings. Tenor. The fret spacing helps more than the extra size costs, and it leaves low G open later.
• Your fingers keep landing on two frets at once. Tenor. This is the specific problem it solves.
• Your fingers keep muting the string next door. Check the nut width, not the size. The Córdoba 15TM at 1½ inches is the one to look at.
• Buying for a child. Concert, or a soprano if they are under about ten.
• It has to live in a rucksack. Concert. Three inches sounds trivial until it has to fit in something.
• You want the chiming, bright, unmistakably ukulele sound. Concert.
• You want to play arrangements rather than accompany singing. Tenor, with a low-G set.
• You already play guitar. Tenor, and look at a baritone too — it is tuned to the top four guitar strings.

FAQs

Do concert and tenor ukuleles use the same chords?

Yes, exactly the same. Both are tuned gCEA, so every chord shape, every chart and every lesson transfers between them without a single change. Nothing you learn on one size has to be relearned on the other.

Is a tenor harder to play than a concert?

No, and for most adults it is easier. The strings are about a third tighter, but the numbers involved are small enough that fingertips do not notice. What they do notice is the extra 15 percent of space between the frets, which makes clean chord shapes easier rather than harder. The stretches that get genuinely longer are the wide ones high up the neck, and beginners do not play those.

Does a tenor sound better than a concert?

It sounds deeper and it sustains longer, which suits fingerstyle and solo playing. A concert is brighter with a faster decay, which suits strumming under a voice. Blind, in a room, most people would not call either one better — they would just describe them differently.

Can I put a low G string on a concert ukulele?

You can, and it is a common enough experiment, but it is not what the size is built for. The shorter scale leaves the wound fourth string slack, so it tends to sound dull and go sharp when you fret it. The clearest evidence is what the string makers offer: D’Addario’s ukulele line has more than twenty sets and the only two low-G sets in it are tenor sets.

Which size is better for small hands?

Concert, but not for the reason usually given. The neck is not thinner — Córdoba’s is 17mm at the first fret on every size they build — so it is not about what your hand can wrap around. It is that the frets are closer together, so a shorter reach covers the same chord shape, and the body is easier to hold against you without a strap.

Is a tenor ukulele bigger than a guitar?

Not remotely. A tenor is about 26 inches overall against roughly 40 for a full-size acoustic guitar, and its 17-inch scale is a little over two thirds of a guitar’s 25½. It is the largest common ukulele apart from the baritone, and it is still a small instrument.

What do the capital and lower-case G mean in ukulele tuning?

The case tells you which octave the fourth string is in. Lower-case, as in gCEA, means the high G of standard re-entrant tuning, where the fourth string sits above the third. Capital, as in GCEA, means the low G an octave down, which needs a specific wound string. Kala states it that way round on their own tuning guide, and it is worth getting right before you order strings.

What about soprano and baritone?

A soprano is 13½ inches of scale, the traditional size, the cheapest and the right answer for children. A baritone is 20 inches and tuned DGBE like the top four strings of a guitar, so it is a different instrument in practice — none of your gCEA chord shapes carry over. Concert and tenor are the two sizes most adults are actually choosing between, which is why they are the ones worth comparing carefully.
