To ask about a group’s age in Spanish, say “¿Cuántos años tienen?” and swap in “usted” forms when you want extra politeness.
You’ve got a group photo today, a classroom roster, or a story about someone’s kids, and you want one clean Spanish line that asks their ages. Spanish does this with the verb tener (to have), not ser (to be). That single detail explains most of the wording you’ll see.
How Old Are They In Spanish In Real Conversations
The most common way to ask “How old are they?” is:
- ¿Cuántos años tienen? (How old are they?)
If you’re speaking to one person about several people, this is still the line you use. You’re asking about them, so the verb stays in the plural: tienen.
If you want a softer tone, you can add a small context word at the end. These don’t change the meaning; they change the vibe.
- ¿Cuántos años tienen ya? (How old are they now?)
- ¿Cuántos años tienen ahora? (How old are they now?)
Why Spanish Uses “Tener Años” For Age
English treats age like an identity: “They are ten.” Spanish treats age like something you possess: “They have ten years.” That’s why the core pattern is tener + number + años.
Once you learn that pattern, lots of phrases snap into place:
- Tienen diez años. (They’re ten.)
- Tienen dieciséis años. (They’re sixteen.)
- No sé cuántos años tienen. (I don’t know how old they are.)
Pronouns And Verb Forms That Matter
Spanish often drops subject pronouns, so you may not hear “ellos” or “ellas.” The verb ending carries the meaning.
Here are the forms you’ll run into most when talking about age:
- tienen = they have
- tiene = he/she has, or you (formal) have
- tienes = you (informal) have
- tenéis = you all (informal, Spain) have
If “they” is a group of women, the question stays the same: ¿Cuántos años tienen? Spanish uses cuántos with años since año is masculine.
When You’ll Hear “Ellos” Or “Ellas”
You’ll hear pronouns when the speaker wants contrast or clarity.
- ¿Y ellos cuántos años tienen? (And how old are they?)
- Ellas tienen ocho y once. (They’re eight and eleven.)
Polite And Formal Ways To Ask Their Ages
Sometimes you’re asking a parent, a teacher, or an older adult. Spanish lets you raise the politeness level by using usted language, even while asking about “they.”
These sound natural in a school, clinic, office, or interview setting:
- ¿Cuántos años tienen? (neutral)
- ¿Me dice cuántos años tienen? (Would you tell me how old they are?)
- ¿Cuántos años tienen los niños? (How old are the kids?)
That second option works well when you want courtesy without sounding stiff. It’s also handy on the phone.
Common Mix-Ups And How To Fix Them
Most mistakes come from translating word-by-word from English. Here are the ones to watch for, plus a clean fix.
Using “Ser” For Age
Not this: “¿Qué edad son?”
Say this:¿Cuántos años tienen? or ¿Qué edad tienen?
¿Qué edad tienen? is also correct and is heard often. It feels a touch more direct, and it’s nice when you don’t want to repeat años.
Forgetting Agreement With “Edad”
Edad is feminine, so if you use an adjective, it follows feminine forms.
- ¿Qué edad tienen?
- ¿Qué edad exacta tienen? (What exact age are they?)
Mixing “Cuánto” And “Cuántos”
Use cuántos with años because año is masculine and plural in this question.
Quick Context Add-Ons That Make Your Spanish Sound Natural
Spanish speakers often pin the question to a person or a situation so the listener answers faster.
- ¿Cuántos años tienen tus hermanos? (How old are your siblings?)
- ¿Cuántos años tienen tus hijos? (How old are your kids?)
- ¿Cuántos años tienen en este grado? (How old are they in this grade?)
- ¿Cuántos años tienen cuando empiezan? (How old are they when they start?)
If you’re talking about a mixed-age group, you can ask for ranges:
- ¿De qué edades son? (What ages are they?)
- ¿Entre qué edades están? (Between what ages are they?)
¿De qué edades son? works because you’re asking about categories of ages, not stating a single age.
Punctuation And Accent Marks That Keep Meaning Clear
Spanish questions use an opening and closing mark: ¿ at the start and ? at the end. Many learners skip the opening mark in casual texting, yet it reads cleaner when you include it and helps you spot a question fast.
The word años carries a tilde on the ñ. Without it, anos means something else and can land badly. If you’re typing on a phone, press and hold the n button to get ñ. On a computer, you can copy “años” once, then paste it until the muscle memory shows up.
When you write numbers, you can use digits or words. In chat, digits are common: Tienen 12 años. In school work, words often look nicer: Tienen doce años. Both are correct Spanish.
Sound Notes When You Say It Out Loud
In ¿Cuántos años tienen?, the stress falls on cuán and on a in a-ños. Keep años as two beats: a + ños. If you blend it too fast, listeners may miss the noun and wait for you to repeat yourself.
When “Ya” Sounds Natural
Ya works when you last saw the group at a younger age and you’re reacting to how fast they’ve grown. If you’re filling out a form, skip it and stick to the plain question. In casual talk, it adds a friendly hint of surprise without changing the answer.

This table gives you ready-to-use lines for the moments people ask ages: meeting family, talking about students, filling out a form, or chatting at a party.
| Spanish Line | English Meaning | When It Fits |
|---|---|---|
| ¿Cuántos años tienen? | How old are they? | General, friendly, neutral |
| ¿Qué edad tienen? | What age are they? | Direct, common in conversation |
| ¿Me dice cuántos años tienen? | Would you tell me how old they are? | Polite request to an adult |
| ¿Cuántos años tienen ya? | How old are they now? | When you expect they’ve grown |
| ¿Cuántos años tienen los chicos? | How old are the kids? | Talking about children nearby |
| Tienen ___ años. | They’re ___ years old. | Standard reply with a number |
| Tienen ___ y ___ años. | They’re ___ and ___. | Two people with different ages |
| El mayor tiene ___; la menor tiene ___. | The older one is ___; the younger is ___. | Sibling pairs, clear ordering |
| No estoy seguro; creo que tienen ___. | I’m not sure; I think they’re ___. | When you’re guessing politely |
Regional Notes You Might Notice
Across Spanish-speaking countries, ¿Cuántos años tienen? travels well. Differences show up in pronouns and everyday words around it.
In Spain, you may hear vosotros forms when speaking to a group directly, yet the “they” form stays tienen. In parts of Latin America, you may hear vos for “you,” yet again, “they” is still tienen.
If you’re learning from shows, you may also hear age asked with names:
- ¿Cuántos años tienen Ana y Luis?
- ¿Qué edad tienen tus primas?
How To Answer Smoothly Without Sounding Stiff
When someone asks ages, the clean reply is just the number. Spanish doesn’t require “years old” since años already does that job.
Here are reply patterns you can reuse:
- Tienen doce años.
- Ella tiene nueve y él tiene once.
- Todos tienen dieciocho. (Everyone is eighteen.)
- Casi tienen quince. (They’re almost fifteen.)
That last one is handy when a birthday is close. You can also say van a cumplir to talk about an upcoming birthday:
- Van a cumplir diez. (They’re turning ten.)
Numbers That Trip People Up
Spanish numbers in the teens and twenties can feel slippery at first. If you want fewer slips, practice saying the whole phrase, not just the number.
- Tienen dieciséis años.
- Tienen diecinueve años.
- Tienen veintiún años. (veintiún before a masculine noun like años)
