How Long Does It Take to Learn a Language? (Realistic Timelines)
For an English speaker, reaching professional working proficiency takes about 550 to 700 class hours for languages close to English (Spanish, French, Italian, Dutch, Portuguese, the Scandinavian languages) and about 2,200 class hours for Arabic, Chinese, Japanese and Korean, according to the US Foreign Service Institute. That is full-time study. At a few hours a week, the same goal takes years, while a solid conversational level (CEFR B1) is realistic in about one to two years for most people.
The honest answer depends on three things: which language, what you mean by “learn,” and how many hours a week you actually put in. This guide gives you the published numbers, shows how to turn them into a timeline for your own week, and covers what genuinely shortens it.
What the Foreign Service Institute says
The Foreign Service Institute (FSI) trains US diplomats, and it publishes how long its students usually take to reach a score of 3 in speaking and listening on the Interagency Language Roundtable (ILR) scale, often called “general professional proficiency.” These are the figures on the State Department’s foreign language training page, checked in September 2026:
| FSI category | Weeks of training | Class hours | Languages |
|---|---|---|---|
| Category I: languages close to English | 24 to 30 | 552 to 690 | Danish, Dutch, Italian, Norwegian, Portuguese, Romanian, Swedish (24 weeks); French, Spanish (30 weeks) |
| Category II | About 36 | 828 | German, Haitian Creole, Indonesian, Malay, Swahili |
| Category III: “hard languages” | About 44 | 1,012 | Many, including Russian, Greek, Hindi, Hebrew, Polish, Turkish, Thai, Vietnamese, Ukrainian |
| Category IV: “super-hard languages” | 88 | 2,200 | Arabic, Chinese (Cantonese and Mandarin), Japanese, Korean |
Two details on that page matter more than the table itself. First, a typical FSI week is 23 hours in class plus 17 hours of self-study, so the class-hour figure is only part of the effort. Second, the FSI says the actual time varies with the learner’s natural ability, prior language-learning experience and time spent in the classroom.
If you want to see why Spanish sits in Category I and Japanese in Category IV, our guide to the easiest languages to learn for English speakers walks through each one.
What does “learn a language” actually mean?
“How long does it take to learn a language” has no single answer because “learn” means very different things. The most common yardstick is the Common European Framework of Reference (CEFR), which describes six levels by what you can do:
- A1 and A2 (basic): introduce yourself, handle simple, familiar exchanges, shop, order, ask directions.
- B1 (threshold): get by in most everyday situations, talk about your life, plans and opinions, even if slowly and with mistakes.
- B2 (vantage): hold a spontaneous conversation with native speakers without much strain on either side. Most people mean something like this when they say “fluent.”
- C1 and C2 (proficient): use the language flexibly for work and study, follow nuance, humor and fast speech.
The FSI’s goal, ILR level 3, is a professional standard. It is often compared to around C1, although the two scales were built for different purposes and do not map exactly. In other words, the FSI numbers describe a high bar, well beyond chatting comfortably with a friend.
Hours per CEFR level
The CEFR itself does not assign hours to levels. The most widely cited estimate comes from Cambridge English, which suggests approximate guided learning hours for learners of English to reach each level, counted from the start:
| CEFR level | Approximate cumulative guided learning hours (Cambridge English, for English) |
|---|---|
| A2 | 180 to 200 |
| B1 | 350 to 400 |
| B2 | 500 to 600 |
| C1 | 700 to 800 |
| C2 | 1,000 to 1,200 |
Cambridge presents these as a guideline only. “Guided learning hours” means time in a class or program, including homework, and the figures are for English. For an English speaker learning a Category IV language, expect every level to take noticeably longer.
How weekly hours turn into months
The published figures are in hours; your life is in weeks. Here is how the two connect. The numbers below are an illustration built from simple arithmetic, not a prediction or a study. They assume the hours are real, focused practice and that you keep going without long breaks.
Example 1: reaching B1, using Cambridge’s 350 to 400 hours as a rough guide.
| Your weekly time | Weeks needed (350 to 400 hours) | Roughly |
|---|---|---|
| 3 hours a week | 117 to 133 weeks | 2.2 to 2.6 years |
| 5 hours a week | 70 to 80 weeks | 16 to 18 months |
| 7 hours a week (1 hour a day) | 50 to 57 weeks | about a year |
| 10 hours a week | 35 to 40 weeks | 8 to 9 months |
The arithmetic: 350 hours divided by 5 hours a week is 70 weeks, and 400 divided by 5 is 80. Divide by about 4.3 to get months.
Example 2: the FSI goal for Spanish. Spanish is listed at 30 weeks. At 23 class hours plus 17 self-study hours, that is 30 × 40 = about 1,200 hours of total effort. At 10 hours a week, 1,200 hours is 120 weeks, or roughly two and a third years. At 5 hours a week, it is closer to five years.
That second example is sobering, but remember what it measures: a professional level, reached by adults studying under pressure for a diplomatic posting. Most learners are well served by B1 or B2, which the same arithmetic puts within reach in roughly one to two and a half years of steady practice.
Why some people learn faster than others
The FSI names ability, experience and time in class. In practice, these are the factors that move your timeline the most:
- How close the language is to one you know. English speakers get a head start in Romance and Germanic languages from shared vocabulary. A Spanish speaker learning Italian or Portuguese starts even further ahead; our Italian and Spanish comparison shows how much overlaps.
- A second foreign language is faster than the first. Knowing how to learn a language, how to handle grammar, drill vocabulary and survive confusion, carries over.
- A new writing system. Every Category I and II language uses the Latin alphabet. A new script is a real, separate task; the alphabet tools help with the first step.
- Consistency. Thirty minutes every day beats a four-hour burst once a week, because you keep reviewing before you forget. We made the case in why consistent practice is key.
- How much you speak. Learners who only read and listen often understand far more than they can say. Speaking is a separate skill that needs its own hours.
What actually speeds it up
You cannot cheat the hours, but you can make each hour count for more.
Learn the most frequent words first
A small set of words makes up most of everyday speech, which is why frequency lists are such an efficient start. Our guide to how many words you need to be fluent covers the vocabulary research, and the most common words lists give you the first thousand words in dozens of languages, for example Spanish.
Use spaced repetition for vocabulary
Reviewing a word just before you would forget it is the most time-efficient way to keep it. Ten to twenty minutes a day with a flashcard app is enough for most learners.
Start speaking early
Waiting until you “know enough” to speak is the most common way to lose a year. Start with short, low-pressure exchanges, voice messages or text chat, and build up. Our guide on how to improve your speaking in a foreign language has a 30-day plan.
Get corrected
Mistakes that nobody points out tend to stick. A tutor, a teacher or a language exchange partner who corrects you speeds things up because you stop practicing errors.
This is where an app like LangX fits. It matches you with people who speak the language you are learning and are learning yours, so the exchange works in both directions. You can hold any message to correct it, and corrections are unlimited on every plan, including Free. You can send voice and photo messages, and translation is built into the chat. LangX does not do live calls, so if you want real-time conversation you will need to add a tutor or a meetup.
Measure progress so you notice it
Progress feels slow from the inside. Take a vocabulary test every couple of months, for example the Spanish vocabulary test, and keep old voice recordings so you can hear the difference.
Make it easy to keep going
Most people who “fail” at a language simply stopped. Pick a daily minimum so small you will do it on your worst day, and see our tips on staying motivated.
Realistic timelines at a glance
Putting the published numbers and the arithmetic together, here is a reasonable expectation for an English-speaking adult learner doing about 5 to 7 hours of focused practice a week. Treat it as a planning range, not a promise.
| Goal | Category I (e.g. Spanish, French) | Category IV (e.g. Japanese, Korean) |
|---|---|---|
| Survival basics (A1 to A2) | 3 to 6 months | 6 to 12 months |
| Everyday conversation (B1) | 1 to 1.5 years | 2 to 3 years |
| Comfortable fluency (B2) | 1.5 to 2.5 years | 3 years or more |
| Professional level (about C1 / ILR 3) | several years at this pace | many years at this pace |
These ranges are extrapolated from the Cambridge and FSI hour figures above, scaled roughly for the harder languages. Your own pace could be faster or slower.
FAQ
How long does it take to learn Spanish?
The FSI lists Spanish at 30 weeks of full-time training (690 class hours, plus self-study) to reach professional proficiency. For a conversational B1 level at around an hour a day, a year is a realistic target.
Can you learn a language in 3 months?
You can reach a useful basic level in three months, especially in a language close to English and with daily practice. Fluency in three months is not realistic for most people; the published hour figures simply do not fit into that window at a normal weekly pace.
How many hours a day should I study a language?
Consistency matters more than volume. Thirty to sixty minutes a day, mixing vocabulary, listening and some speaking or writing, is sustainable for most people and adds up to 3.5 to 7 hours a week.
Which languages take longest for English speakers?
Arabic, Mandarin, Cantonese, Japanese and Korean. The FSI puts them in Category IV at 88 weeks, about three times as long as Spanish or Dutch.
Does a language exchange make you learn faster?
It adds the part most self-study lacks: real conversation with someone who corrects you. It works best alongside vocabulary and listening work, not instead of it. Our guide on how to do a language exchange explains how to set one up well.
