How Long Does It Take to Learn a Language?
The honest hour counts, from the institutions that actually measure them, compared across languages and levels.

Updated July 30, 2026
How long it takes to learn a language depends on which language and how well you want to speak it. For an English speaker, the US Foreign Service Institute puts an easier language like Spanish or French at about 600 to 750 hours of study to reach professional working proficiency, and a hard one like Japanese or Arabic at around 2,200. Conversational ability comes far sooner. This page compares the estimates across languages and across the CEFR levels, and flags the timing claims that get repeated but do not hold up.

How long each language takes
The Foreign Service Institute sorts languages by how far they sit from English. Its easiest group, which includes Spanish, French, and Italian, takes roughly 600 to 750 class hours to professional working proficiency; the hardest, like Japanese, Korean, and Arabic, around 2,200. These are intensive-instruction estimates, so treat them as a relative ranking rather than a promise.
| Language | Estimated hours | Difficulty |
|---|---|---|
| 🇪🇸 Spanish | ~600 hrs | one of the easier languages for English speakers |
| 🇫🇷 French | ~600 hrs | a moderately challenging language for English speakers |
| 🇮🇹 Italian | ~600 hrs | one of the easier languages for English speakers |
| 🇩🇪 German | ~750 hrs | a moderately challenging language for English speakers |
| 🇮🇩 Indonesian | ~900 hrs | one of the easier languages for English speakers |
| 🇯🇵 Japanese | ~2200 hrs | one of the more challenging languages for English speakers |
| 🇰🇷 Korean | ~2200 hrs | one of the more challenging languages for English speakers |
Hours are FSI-informed estimates to professional working proficiency. Tap a language for what that looks like at a casual, steady, or intensive pace.
How long each CEFR level takes
Cambridge English estimates roughly 200 guided hours to move from one CEFR level to the next, counted cumulatively from a standing start. These are guidelines, not guarantees, and the CEFR itself defines levels by what you can do rather than by hours.
| Level | Guided hours | What you can do |
|---|---|---|
| A1 | 90 to 100 hrs | Use very basic phrases, introduce yourself, and ask and answer simple personal questions. |
| A2 | 180 to 200 hrs | Handle short, routine exchanges on familiar topics like shopping, directions, and daily life. |
| B1 | 350 to 400 hrs | Cope with most situations while travelling, and follow the main points of clear standard speech. |
| B2 | 500 to 600 hrs | Interact with some fluency and spontaneity, and follow much native TV and film with effort. |
| C1 | 700 to 800 hrs | Use the language flexibly and effectively for social, academic, and professional life. |
| C2 | 1,000 to 1,200 hrs | Understand almost everything you read or hear with ease, close to a native speaker. |
Numbers to retire: timing myths
A few timing claims get repeated everywhere but do not hold up. Here is what the evidence actually says.
Not supported
It takes 10,000 hours to learn a language.
The 10,000-hour rule does not apply to languages. It is a popularisation of a 1993 study of violinists whose author, Anders Ericsson, said it was misused. It was never a threshold and never about language. Use the FSI and CEFR hour bands on this page instead.
Not supported
It takes 480 hours to become fluent.
480 hours is not an FSI figure. The Foreign Service Institute's lightest course is about 600 class hours, and it targets professional working proficiency, not the vague word fluency. Treat 480 hours as an unsourced popularisation.
Not supported
You can become fluent in three months.
Fluent in three months is a marketing phrase, not a research finding. It is the title of a book built on personal challenges, with fluency redefined toward conversational confidence. Useful basics come fast; professional fluency in three months does not.
The fastest path is the hours you actually keep logging. LingoBinge turns Netflix shows into comprehensible input at your level, so watch time counts toward these hours instead of competing with them.

Frequently asked questions
- How long does it take to learn a language?
- For an English speaker, the US Foreign Service Institute estimates about 600 to 750 hours for an easier language like Spanish and up to about 2,200 for a hard one like Japanese, to reach professional working proficiency. Conversational ability at B1 comes sooner, around 350 to 400 guided hours by Cambridge's estimate.
- What is the easiest language to learn for English speakers?
- The FSI groups Spanish, French, Italian, Portuguese, and a handful of others as its easiest category, at roughly 600 to 750 class hours. They share a lot of vocabulary and grammar with English, which is why they take about a third of the time of a language like Japanese, Korean, or Arabic.
- How many hours a day should I study to learn a language?
- There is no single right amount, but the math is encouraging. At one focused hour a day, an easier language's 600 to 750 hours is under two to three years, and much of that time can be enjoyable input like graded TV rather than drills, which makes the hours easier to keep logging.
- Can you become fluent in three months?
- Not to a professional level. The lightest FSI course is about 600 hours and targets working proficiency, so three months of casual study will not reach it. You can pick up useful conversational basics quickly, which is what most fast-fluency claims really describe.
