Learning how to ask and answer the question "How old are you?" is one of the foundational steps in mastering the Spanish language, but it comes with a major, non-negotiable grammatical twist. Unlike English, where you "are" a certain age, in Spanish, you literally "have" a certain number of years. This critical difference is the key to sounding natural and avoiding one of the most common mistakes non-native speakers make. As of December 12, 2025, mastering this phrase involves understanding not just the words, but the proper verb conjugation and the cultural context of formality.
This comprehensive guide will break down the essential phrases, the grammar rules behind the verb *tener* (to have), and the critical cultural etiquette you need to navigate conversations about age in any Spanish-speaking country, from Madrid to Mexico City.
The Essential Grammar Rule: Why Spanish Speakers "Have" Years, Not "Are" Years
The most important concept to grasp when discussing age in Spanish is the use of the verb tener, which means "to have." This is a direct contrast to English, which uses the verb "to be" (ser or estar in Spanish). Spanish speakers perceive age as a quantity of years that one possesses, rather than a state of being. Trying to translate the English phrase directly, such as saying "Soy veinte años" (I am 20 years), is grammatically incorrect and is a dead giveaway that you are a beginner.
The Core Question and Answer
The standard way to ask "How old are you?" is:
- ¿Cuántos años tienes? (Informal/Familiar)
This literally translates to: "How many years do you have?"
The standard way to answer is:
- Tengo [número] años. (I have [number] years.)
For example, to say "I am 30 years old," you would say: Tengo treinta años.
7 Crucial Rules for Asking About Age in Spanish
To achieve topical authority and fluency, you must navigate the nuances of formality, verb conjugation, and alternative phrases. These seven rules cover everything you need to know.
1. Master the Formal vs. Informal Distinction
Spanish grammar requires you to use different verb forms depending on your relationship with the person you are speaking to. This is known as the formal (usted) and informal (tú) distinction.
- Informal (Tú): Used with friends, family, peers, children, and anyone you know well.
- Question: ¿Cuántos años tienes?
- Formal (Usted): Used with elders, superiors, strangers, or in professional settings where respect is paramount.
- Question: ¿Cuántos años tiene (usted)?
2. Conjugate the Verb 'Tener' Correctly
The verb *tener* (to have) is irregular. When discussing age, you will primarily use the present tense conjugations for the first, second, and third person.
| Pronoun | Tener Conjugation | English Translation |
|---|---|---|
| Yo (I) | Tengo | I have (I am) |
| Tú (You, informal) | Tienes | You have (You are) |
| Él/Ella/Usted (He/She/You, formal) | Tiene | He/She/You have (He/She/You are) |
| Nosotros/Nosotras (We) | Tenemos | We have (We are) |
| Ellos/Ellas/Ustedes (They/You all) | Tienen | They/You all have (They/You all are) |
3. Use the Alternative Phrase: ¿Qué edad?
While *¿Cuántos años tienes?* is the most common and natural phrase, you may occasionally hear a more direct question using the noun *edad* (age).
- ¿Qué edad tienes? (Informal) - "What age do you have?"
- ¿Qué edad tiene (usted)? (Formal)
This is a perfectly acceptable variation, though the *cuántos años* phrase is overwhelmingly preferred in everyday conversation.
4. Know the Cultural Etiquette of Asking Age
In many Spanish-speaking cultures, particularly in Spain, asking a direct question about a woman's age in a casual setting can be considered impolite or intrusive, similar to English-speaking cultures. However, in other regions, such as Colombia, the question can be more casual and often leads into a pleasant conversation about family and life stories.
- Rule of Thumb: Always start with the formal usted form if you are unsure of your relationship with the person or if they are significantly older than you. It is better to be overly polite than inadvertently rude.
- Safe Alternative: If you need to know someone's age for a formal reason (e.g., a doctor's office or administrative task), the question is acceptable. If it's purely for casual conversation, it's often safer to wait for the topic to come up naturally.
5. Learn How to Talk About Other People’s Ages
The same *tener* rule applies when talking about a third person, such as a sibling, child, or friend. You simply use the appropriate conjugation:
- Mi hermana tiene veinticinco años. (My sister is 25 years old.)
- ¿Cuántos años tiene tu hijo? (How old is your son?)
- Mis padres tienen setenta y dos años. (My parents are 72 years old.)
6. Understand Age-Related Vocabulary (LSI Keywords)
To expand your topical authority, incorporate these related terms naturally into your conversations:
- años: years
- edad: age (noun)
- cumpleaños: birthday (noun)
- Feliz cumpleaños: Happy birthday
- joven: young
- mayor: older/major (often used to politely refer to someone's age)
- menor: younger/minor
- cumplir: to turn (an age), e.g., Voy a cumplir treinta (I am going to turn thirty)
7. Know How to Talk About Age in the Past
If you need to talk about someone's age in the past, you must use the imperfect tense of *tener* (the past tense used for ongoing or habitual actions, like being a certain age for a period of time).
- Question: ¿Cuántos años tenías? (How old were you?)
- Answer: Tenía diez años. (I was ten years old.)
This is a more advanced grammatical structure, but essential for sounding like a native speaker when recounting memories or stories.
Advanced Phrases for Age and Milestones
Beyond the basic question, there are several ways to discuss age and life stages that will significantly enhance your fluency and demonstrate mastery of the language.
Phrases for Youth and Adulthood
- Es un niño/una niña. (He/She is a child.) - Note: Regional variations exist for the word "child," such as chico/chica or muchacho/muchacha.
- Es un adolescente. (He/She is a teenager.)
- Es un adulto/una adulta. (He/She is an adult.)
- Es de la tercera edad. (He/She is a senior citizen/elderly.)
- Está en sus veintes/treintas. (He/She is in their twenties/thirties.)
Phrases for Birthdays and Celebrations
Birthdays are a common time to discuss age. Knowing these phrases is vital for social interaction:
- ¿Cuándo es tu cumpleaños? (When is your birthday?)
- Mi cumpleaños es el [fecha]. (My birthday is on [date].)
- ¡Que cumplas muchos más! (May you turn many more!) - A common, warm birthday wish.
- La fiesta de cumpleaños. (The birthday party.)
- Soplar las velas. (To blow out the candles.)
By internalizing the core rule—that Spanish speakers have years (*tener años*)—and applying the correct formal or informal conjugation, you will confidently and correctly ask and answer "How old are you?" in Spanish. This fundamental concept is a cornerstone of fluency and is the first step toward unlocking deeper, more engaging conversations with native speakers.
