How long it takes to learn French — NoaLingua

A real number, with its assumptions stated

The US Foreign Service Institute puts French at 600 to 750 class hours to professional working proficiency — 24 to 30 weeks full time, its joint-shortest estimate. At an hour a day that is about two years. Reading arrives much sooner than that; listening arrives later.

Why the number is mostly about what happens between sessions

Hour counts assume the hours accumulate. They mostly do not: you meet a word, you understand it, and unless something brings it back it is gone within days, so a share of every hour goes on re-learning what the last one taught.

That leak is what NoaLingua closes. Words and sentences you save come back on a spaced schedule, just before you would have forgotten them, with the clip still attached — so the hours compound instead of resetting.

The schedule decides, not you: Saved sentences return on spaced intervals rather than when you happen to think of them. Nothing to plan and nothing to file.
Sound and text together: A card carries the sentence and the moment it was said, which in French matters more than elsewhere — you re-meet the phrase as sound, not only as spelling.
Hours you were spending anyway: The material is whatever you were going to watch or read. That is the only honest way most people find an hour a day for two years.

The figure, and where it comes from

The Foreign Service Institute has taught languages to American diplomats since 1947 and measures how long each takes. French sits in Category I — the joint-easiest band, shared with Spanish, Italian, Portuguese and others — at 600 to 750 class hours, roughly 24 to 30 weeks of full-time study, to General Professional Proficiency.

Against the Category IV languages at about 2,200 hours, French is roughly a quarter of the work. If speed is a factor in choosing, that gap is worth more than any opinion about which language is more useful.

Why French timelines mislead more than Spanish ones

A single number hides an unusually wide split in French. Reading comes fast, because so much English vocabulary is French in origin and the written language is regular. Listening comes slowly, because liaison, elision and silent endings mean the spoken form does not segment the way the written form does.

So a French learner at 200 hours is frequently reading at one level and listening at a much lower one, and the composite figure describes neither. This is worth knowing in advance, because the usual interpretation of that gap — that you are bad at languages — is wrong, and the usual response, more reading, makes it worse.

At three hours a day: Around eight months to the bottom of the band, if the hours are real and include listening. Reading will run ahead of that; the ear will lag.
At one hour a day: About two years, and a perfectly good outcome for somebody with a job. Split the hour rather than spending it all on one skill.
At twenty minutes a day: Six years on paper, and the arithmetic breaks down here — at that rate forgetting between sessions consumes a large share of each one.

The milestones that arrive much earlier

Professional working proficiency is a high bar and almost nobody needs it. Reading a French news article with occasional lookups is achievable in a couple of months, thanks to the shared vocabulary. Holding a slow, patient conversation follows not long after.

Following a French film without a translated line on screen is the real milestone, and in French it is later than learners expect — commonly somewhere past 400 hours, and it depends enormously on the film. Dubbed material and news broadcasts come far sooner than cinema, and mistaking the difficulty of one for the difficulty of the other is a routine source of discouragement.

What the evidence says

Each of these has a source and a date. Where we could not find one, the claim is not here.

French is Category I: 600–750 class hours, 24–30 weeks, to General Professional Proficiency.: The joint-shortest published estimate for an English speaker, and about a quarter of the Category IV figure for Japanese, Korean and Chinese. US Foreign Service Institute language difficulty categories, checked 2026-08-26
The FSI figure is intensive classroom time — around 25 hours a week — plus three to four hours of daily individual study.: Quoting 600 hours without this caveat is the most common mistake with the number. Compare total hours, never elapsed months. FSI programme structure, as described alongside the category tables, checked 2026-08-26
New material decays sharply within the first day unless it is retrieved again.: Why hour counts mislead. An hour without retrieval afterwards is not a whole hour of progress. Ebbinghaus’s forgetting curve, summarised with sources on our blog

From people who have done it

Time to proficiency is driven far more by how different the language is from your own than by aptitude or method.

Common questions about NoaLingua

Can I learn French in three months?

You can reach a useful conversational level in three months at several hours a day, and you will not reach professional proficiency. Anybody promising the second in three months is contradicting the FSI’s own data.

Is French harder than Spanish?

They share the FSI’s easiest band, so the cost is about the same. French is markedly harder to hear and no harder to read; Spanish is easier to pronounce and has a harder tense distinction in the middle.

Why is my French listening so far behind my reading?

Because spoken French does not segment the way written French does — liaison and elision weld words together and most final consonants are silent. It is normal, it is the defining French difficulty, and it needs listening with text rather than more reading.

Does knowing Spanish make French faster?

Yes, considerably, for reading and grammar — the tense systems are close cousins. It does much less for listening, which is exactly where French is hard.
