How Long Does It Take to Learn a Language?
By Bengi Coskun, Co-founder, OGIMA · Last updated 2026-06-11
So how long does it take? It depends on two things: which language you picked, and how many hours you actually put in. There is no fixed answer, and anyone selling you “fluent in 30 days” is selling you something. The honest version: roughly 600 hours of focused work for an easy language like Spanish, and three to four times that for a hard one like Arabic or Japanese.
That is the short answer. The longer one matters, because “learn a language” hides a huge range, from ordering a coffee to arguing politics. The hours below come from the US Foreign Service Institute, which has tracked how long it takes English speakers to reach a professional level across dozens of languages over decades. Real data, not vibes. Here is how to read it.
How long does it really take?
Start with the most-cited number in language learning: the FSI estimates. The Foreign Service Institute trains US diplomats, and it has measured, for seventy-odd years, how many class hours its students need to hit professional working proficiency in each language. That is a high bar, equivalent to “Speaking-3 / Reading-3” on the government scale, well above casual conversation.
The headline: an easy language runs about 600 to 750 hours. A super-hard one runs about 2,200. Everything else falls between. These are full-time, intensive, classroom hours with motivated adult learners and good teachers. Your mileage will differ. But as a baseline for comparing languages against each other, nothing beats it.
The FSI hour estimates by language difficulty
FSI sorts languages into difficulty categories by how long they take English speakers to reach professional working proficiency. The hours are class hours; the weeks assume roughly 25 hours of class per week, full-time.
| Category | Example languages | Approx hours | Approx full-time weeks |
|---|---|---|---|
| I (easiest) | Spanish, French, Italian, Portuguese, Dutch, Romanian | 600–750 | 24–30 |
| II | German | ~750 | ~30 |
| III | Indonesian, Swahili, Malay | ~900 | ~36 |
| IV (hard) | Russian, Hindi, Turkish, Polish, Thai, Vietnamese, Finnish | ~1,100 | ~44 |
| V (super-hard) | Arabic, Mandarin Chinese, Cantonese, Japanese, Korean | ~2,200 | ~88 |
A few notes. German gets its own near-Category-II slot because cases and word order slow English speakers down without making it truly hard. Japanese is sometimes flagged as the hardest even within Category V because of the writing system. And these are professional-level hours. You will be chatting long before you finish them. Source for the table is FSI, cited at the bottom.
What does “fluent” even mean?
Here is where most timeline arguments go sideways. People mean wildly different things by “fluent.” The CEFR scale, the standard European framework, splits proficiency into six levels, and they are not evenly spaced.
- A1–A2 (basic user): survival language. Greetings, shopping, simple questions, familiar topics. A few months of steady work.
- B1–B2 (independent user): the conversational sweet spot. At B1 you handle everyday situations and describe experiences. At B2 you hold spontaneous conversations, follow standard speech, and argue a point. Most people would call a confident B2 speaker fluent.
- C1–C2 (proficient user): what linguists actually mean by fluent. At C1 you express yourself almost effortlessly and catch subtext. C2 is near-native command.
So when someone says “I want to be fluent,” they usually mean B2, not C2. That matters enormously for timelines. Conversational ability, around B1 to B2, arrives years before C1 polish. Aiming for C2 when you only need B2 is how people convince themselves it takes a decade.
What makes it faster or slower?
The FSI hours are an average. Four things push you off it, hard.
Languages you already know. Spanish is easy for English speakers partly because it shares vocabulary, an alphabet, and broad sentence logic. If you already speak Italian, Spanish is faster still. A Korean speaker learning Japanese has a head start no English speaker gets. Distance from what you know is the single biggest lever.
Hours per week. This is the obvious one people ignore. Six hundred hours at an hour a day is roughly two years. The same 600 hours full-time is six months. Intensity compresses the calendar; it does not change the hour count.
Motivation, and the kind of motivation. Wanting to talk to your partner’s family beats wanting a line on your CV. Real stakes keep you showing up on the days you would rather not.
How much you actually speak. This is the quiet one. Two learners can log identical hours and end up miles apart, because one spent those hours doing grammar drills and the other spent them talking. Output builds output. Input alone leaves you understanding everything and saying nothing.
How do you learn a language faster?
You cannot cheat the hours. You can spend them far better. In rough priority order:
- Speak from day one. Open your mouth before you feel ready. Producing the language out loud is what builds the ability to produce it, and most of your gains come from there, not from silent study.
- Put in the hours, daily. Thirty minutes every day beats four hours once a week. The FSI hour counts are real, and the only way to burn them down is consistency, because spaced practice is how memory sticks.
- Pick situations you actually face. Rehearse the conversations you will really have, ordering food, a work call, small talk, instead of textbook dialogues. You recall language best in the context where you learned it.
- Get feedback and correct out loud. Find a partner, a tutor, or an AI like OGIMA that talks back and pushes you to fix mistakes in real time, then say the corrected version aloud until it is automatic.
- Front-load comprehensible input. Listen and read a lot at a level you mostly understand, because you cannot produce words you have never heard. Use input to feed speaking, not to replace it.
That ordering is deliberate. Most of the gains come from producing the language, see how to practice speaking a language. Picking up a per-language method helps too, whether that is Spanish or German.
How long to just hold a conversation?
Much sooner than the full FSI hours suggest. Those numbers are for a professional level, the top of the mountain. Basic conversation is base camp, and you reach it in weeks to months of real speaking, not years.
If you drill 600 hours of grammar and never talk, you can still freeze when a waiter asks a question. If you spend even 50 or 80 hours of those actually speaking, in situations close to the ones you care about, you will be holding short conversations surprisingly early. The gap between “studied a lot” and “can talk” is almost entirely time spent talking. Conversational comes first. Fluent comes much later. Aim for the first one and the second takes care of itself. A speaking-first tool like OGIMA is built around exactly this, getting you talking early instead of hoarding hours of silent study.
Frequently asked questions
How long does it take to learn Spanish or French?
Both are FSI Category I languages, about 24 to 30 weeks or 600 to 750 class hours to reach professional working proficiency. At a relaxed hour a day that is closer to two years. Basic conversation comes far sooner, in months.
How long does it take to learn German?
German sits just above the easy group at roughly 30 weeks or 750 class hours for English speakers, a notch harder than Spanish because of the cases and word order, but nowhere near the super-hard languages.
What are the hardest languages for English speakers?
Arabic, Mandarin Chinese, Cantonese, Japanese, and Korean. FSI puts them in Category V at about 88 weeks or 2,200 class hours, roughly three to four times the hours an easy language needs.
How many hours a day should I study?
Thirty minutes to an hour a day, every day, beats long rare sessions. Consistency burns the hours down while keeping memory fresh. Spend most of that time speaking, not just reading or watching.
Can you become fluent in 3 months?
Conversational, maybe, if you go hard and you picked an easy language. Genuinely fluent at C1 or C2 in three months, no, not honestly. Three months of daily speaking can get you holding real conversations, which is a fair definition of progress.
Does speaking make you learn faster?
Yes. Producing the language is what builds production. Task-based, communicative practice shows large engagement and fluency gains in the research, and it lowers the anxiety that keeps people silent. Most of the gains come from producing the language.
