If someone asks your age in Korean, you can answer with 저는 스무 살이에요 jeoneun seumu sarieyo I am twenty years old or, when you want to be exact about international age, 저는 만 스물다섯 살이에요 jeoneun man seumuldaseot sarieyo I am twenty-five in international age. This guide teaches how to build Korean age answers naturally, how to use 살 sal years old, when to add 만 man international age / full age, and how to avoid common beginner mistakes.

The Basic Pattern for Saying Your Age in Korean
The most useful beginner pattern for saying your age in Korean is simple: 저는 ... 살이에요 jeoneun ... sarieyo I am ... years old. This sentence is polite enough for everyday beginner conversations and clear enough for self-introductions, class practice, language exchange, travel, and casual introductions.
The word 저 jeo I / me, polite is a humble first-person word. The topic marker 는 neun topic marker marks what you are talking about. The age part uses a native Korean number plus 살 sal years old. The ending 이에요 ieyo is / am / are finishes the polite sentence.
Why the sentence starts with 저는
The phrase 저는 jeoneun as for me / I is not always required in Korean. Korean often drops the subject when the meaning is obvious. However, for beginners, 저는 jeoneun I / as for me is useful because it makes the sentence structure easy to see.
In a self-introduction, you can say: 저는 스무 살이에요 jeoneun seumu sarieyo I am twenty years old. If someone has just asked your age, you can answer more briefly: 스무 살이에요 seumu sarieyo I am twenty years old.
Why age uses 살 in speaking
The counter 살 sal years old is the everyday spoken age counter. You combine it with native Korean numbers such as 열아홉 yeolahop nineteen, 스무 seumu twenty, before 살, and 서른 seoreun thirty.
The safest beginner sentence
A safe first sentence to memorize is: 저는 스무 살이에요 jeoneun seumu sarieyo I am twenty years old. Replace 스무 seumu twenty, before 살 with your own age number. This pattern is polite, short, and useful in many beginner conversations.
Core idea: Build your Korean age answer with a native Korean number plus 살이에요 sarieyo am / is / are years old.
The basic age answer is 저는 ... 살이에요 jeoneun ... sarieyo I am ... years old. Use this as your main beginner pattern.
Native Korean Numbers for Age
Korean has two number systems. For age in everyday speech, you usually need native Korean numbers. This is why saying your age is not as simple as reading a digit. The sentence pattern is easy, but the number inside the pattern needs practice.
The age numbers beginners need first
Many beginners first need ages from ten to thirty because these are common in classroom, travel, and language exchange conversations. Instead of memorizing a long list at once, learn age numbers as chunks that attach naturally to 살 sal years old.
Full answer: 저는 열아홉 살이에요 jeoneun yeolahop sarieyo I am nineteen years old.
Full answer: 저는 스무 살이에요 jeoneun seumu sarieyo I am twenty years old.
Full answer: 저는 스물한 살이에요 jeoneun seumulhan sarieyo I am twenty-one years old.
Full answer: 저는 서른 살이에요 jeoneun seoreun sarieyo I am thirty years old.
Why native Korean numbers matter
In Korean, counters often decide which number system sounds natural. Age with 살 sal years old normally uses native Korean numbers in everyday speech. That is why 스무 살 seumu sal twenty years old sounds natural, while directly saying a Sino-Korean number with 살 sal years old can sound unnatural in ordinary conversation.
Age chunks are easier than number lists
A good study method is to memorize age chunks, not isolated numbers. Instead of only memorizing 스물 seumul twenty, memorize 스무 살 seumu sal twenty years old and 스물한 살 seumulhan sal twenty-one years old. These chunks prepare you for real speaking faster.
Once you know the pattern 저는 ... 살이에요 jeoneun ... sarieyo I am ... years old, you only need to replace the number chunk.
For everyday age answers, learn native Korean number chunks with 살 sal years old, not numbers alone.
Why Twenty Becomes 스무 살
One of the most important beginner details is the difference between 스물 seumul twenty and 스무 살 seumu sal twenty years old. When the number twenty comes directly before 살 sal years old, it commonly appears as 스무 seumu twenty, before a counter.
The number changes before a counter
Native Korean numbers often have special forms before counters. For age, the most visible beginner example is: 스물 seumul twenty becoming 스무 살 seumu sal twenty years old. This is why 저는 스무 살이에요 jeoneun seumu sarieyo I am twenty years old is the natural sentence.
Number by itself: 스물 seumul twenty
Before the age counter: 스무 살 seumu sal twenty years old
Full sentence: 저는 스무 살이에요 jeoneun seumu sarieyo I am twenty years old
Twenty-one keeps 스물
Another detail surprises learners: 스무 살 seumu sal twenty years old uses 스무 seumu twenty, before 살, but 스물한 살 seumulhan sal twenty-one years old keeps 스물 seumul twenty before 한 살 han sal one year old / one year in age counting.
So the natural answers are: 저는 스무 살이에요 jeoneun seumu sarieyo I am twenty years old and 저는 스물한 살이에요 jeoneun seumulhan sarieyo I am twenty-one years old.
Other useful decade forms
Beginners also benefit from recognizing decade age chunks: 서른 살 seoreun sal thirty years old, 마흔 살 maheun sal forty years old, and 쉰 살 swin sal fifty years old. You do not need every number on day one, but you should learn the forms you will actually say about yourself.
Beginner note: Do not say 스물 살이에요 seumul sarieyo intended meaning: I am twenty years old as your main beginner answer. Use 스무 살이에요 seumu sarieyo I am twenty years old instead.
Memorize 스무 살 seumu sal twenty years old as a fixed age chunk. Then practice 스물한 살 seumulhan sal twenty-one years old separately.
Saying International Age with 만
Korean learners often meet the word 만 man international age / full age counted by birthdays when age needs to be exact. A clear beginner sentence is 저는 만 스물다섯 살이에요 jeoneun man seumuldaseot sarieyo I am twenty-five in international age.
What 만 means in an age answer
In age expressions, 만 man full age / international age signals that the age is counted by completed birthdays. This is the age system commonly used in international contexts and official Korean settings. In 2023, South Korea standardized the use of the international age-counting method for many legal and administrative contexts, but learners may still hear older-style everyday age talk in casual conversation.
When to include 만
Use 만 man international age / full age when accuracy matters. It is helpful for forms, immigration, healthcare, school records, official profiles, legal age, or any situation where birthday-based age is important. In everyday friendly conversation, people may simply say 스물다섯 살이에요 seumuldaseot sarieyo I am twenty-five years old if the context is already clear.
만 before the number
Place 만 man international age / full age before the age number: 만 스물다섯 살 man seumuldaseot sal twenty-five years old in international age. Then finish the sentence with 이에요 ieyo am / is / are.
International age and everyday speech
A learner may hear both: 스물다섯 살이에요 seumuldaseot sarieyo I am twenty-five years old and 만 스물다섯 살이에요 man seumuldaseot sarieyo I am twenty-five in international age. The second sentence is clearer when there might be confusion about age counting.
Accuracy tip: When the situation is official, add 만 man international age / full age before your age number.
Use 저는 만 ... 살이에요 jeoneun man ... sarieyo I am ... in international age when your birthday-based age matters.
Short, Full, and Formal Age Answers
You do not always need the same length of answer. Korean often changes depending on the context. You may give a short answer in a conversation, a full answer in a self-introduction, or a formal written answer on a profile.
Short answer after a question
If someone asks: 몇 살이에요? myeot sarieyo? How old are you?, you can answer: 스무 살이에요 seumu sarieyo I am twenty years old. The word 저는 jeoneun I / as for me is not required because the question already makes the subject clear.
Full answer for self-introduction
In a self-introduction, the full version sounds clear: 저는 스무 살이에요 jeoneun seumu sarieyo I am twenty years old. If you are introducing several facts about yourself, it can follow your name and country: 저는 알렉스예요. 저는 스무 살이에요 jeoneun allekseuyeyo. jeoneun seumu sarieyo I am Alex. I am twenty years old.
Formal written answer with 세
The word 세 se years of age is common in written, official, or formal contexts. You may see: 25세 isip-o se twenty-five years of age or 만 25세 man isip-o se twenty-five years of age in international age. In speaking practice, however, 스물다섯 살 seumuldaseot sal twenty-five years old is usually more natural.
Spoken: 저는 스물다섯 살이에요 jeoneun seumuldaseot sarieyo I am twenty-five years old
Exact spoken: 저는 만 스물다섯 살이에요 jeoneun man seumuldaseot sarieyo I am twenty-five in international age
Written or formal: 만 25세입니다 man isip-o se imnida I am twenty-five in international age
Choosing the right answer length
Use the short version when the question is clear. Use the full version when introducing yourself. Use the 만 ... 세 man ... se international age / years of age style in more formal contexts. A learner who understands these three answer styles can sound natural in both casual speaking and official situations.
Say 스무 살이에요 seumu sarieyo I am twenty years old as a short answer, and 저는 스무 살이에요 jeoneun seumu sarieyo I am twenty years old as a full self-introduction answer.
Answering with Your Birth Year Using 년생
Koreans sometimes answer age-related questions with a birth year instead of an age number. A useful beginner word is 년생 nyeonsaeng born in a certain year. For example: 저는 이천일 년생이에요 jeoneun icheonil nyeonsaengieyo I was born in 2001.
Why birth year answers are useful
A birth year can help people understand age, school year, or peer relationship without directly comparing exact ages in the moment. It is also common in casual Korean conversation among people trying to figure out whether they are the same age, older, or younger.
Use Sino-Korean numbers for years
Birth years use Sino-Korean number reading. So 2001년 icheonil nyeon the year 2001 is read differently from native Korean age numbers. This is a common beginner challenge: age with 살 sal years old uses native Korean numbers, but years such as 2001년 icheonil nyeon the year 2001 use Sino-Korean numbers.
Birth year and age answer together
You can combine both if the conversation needs clarity: 저는 이천일 년생이고, 만 스물다섯 살이에요 jeoneun icheonil nyeonsaengigo, man seumuldaseot sarieyo I was born in 2001, and I am twenty-five in international age. This is longer, but it can be useful when age counting might be confusing.
Do not mix the number systems randomly
A common mistake is to use the same number style for everything. Age and years are different. Use 스물다섯 살 seumuldaseot sal twenty-five years old for spoken age, but use 이천일 년생 icheonil nyeonsaeng born in 2001 for a birth year.
Use 저는 ... 년생이에요 jeoneun ... nyeonsaengieyo I was born in ... when you want to answer with your birth year instead of only your age.
Practice Dialogues and Common Mistakes
The fastest way to make age answers natural is to place them inside short dialogues. The grammar is simple, but the number form, the 만 man international age / full age marker, and the choice between 살 sal years old and 세 se years of age need practice.
Dialogue 1: Basic classroom answer
This is the cleanest beginner pattern. The answer repeats the subject with 저는 jeoneun I / as for me because it is a practice dialogue.
Dialogue 2: International age answer
This answer is useful when the exact birthday-based age matters. The word 만 man international age / full age removes possible confusion.
Dialogue 3: Birth year answer
This question-answer pair uses a year, not an age number. The Korean number reading changes because years use Sino-Korean numbers.
Common mistake 1: saying 스물 살 for age twenty
Beginners often say 스물 살이에요 seumul sarieyo intended meaning: I am twenty years old. The natural spoken form is 스무 살이에요 seumu sarieyo I am twenty years old.
Common mistake 2: using 세 in every conversation
The form 25세입니다 isip-o se imnida I am twenty-five years of age is correct in a formal or written style, but it can sound stiff in normal conversation. For everyday speaking, use 스물다섯 살이에요 seumuldaseot sarieyo I am twenty-five years old.
Common mistake 3: forgetting 만 when exact age matters
If the conversation involves forms, legal standards, official records, or birthday-based age, do not leave the meaning unclear. Say 만 스물다섯 살이에요 man seumuldaseot sarieyo I am twenty-five in international age or write 만 25세입니다 man isip-o se imnida I am twenty-five in international age.
Practice note: Learn one age sentence for speaking, 저는 스무 살이에요 jeoneun seumu sarieyo I am twenty years old, and one exact-age sentence, 저는 만 스물다섯 살이에요 jeoneun man seumuldaseot sarieyo I am twenty-five in international age.
Natural age answers need the right number form, the right counter, and the right level of exactness.
