How long does it take to learn French?

The US Foreign Service Institute places French in Category I, the easiest group, estimating 600-750 class hours to reach professional working proficiency. That figure describes full-time intensive instruction for native English speakers with a track record of learning languages, so it is a floor for a favourable case rather than a typical outcome — but it is the most soundly based number available, and it is the FSI's, not ours.

Reading arrives early, listening does not

French is fast to read and slow to hear, and the gap between the two is wider than in any other Category I language. Heavy borrowing into English means the written vocabulary is unusually accessible; liaison, elision and silent final consonants mean the spoken form of the same sentence can be unrecognisable. Learners who track only reading progress conclude French is easy, then stall the first time they try a film. Budgeting listening time from the first month rather than the sixth is the single change that most affects the timeline.

What the FSI number does and does not mean

The estimate comes from diplomatic language training: small classes, full days, motivated adults selected partly for aptitude, and immersion alongside. Almost nobody studying independently matches those conditions, so treat 600-750 class hours as a lower bound under ideal circumstances. The more useful reading is comparative — it tells you reliably that French sits where it sits relative to other languages, which is what most people are really asking.

Hours are the wrong unit anyway

Two people can log identical hours and end up in very different places, because an hour of decoding sentences you barely understand and an hour of reading material pitched just above your level do not produce the same learning. What predicts progress is time spent understanding real language rather than time spent studying about it. The practical implication is to reach material you can mostly follow as early as possible, and then increase the volume.

Frequently asked questions

Why can I read French but not understand it?

Spoken French elides and links words and drops most final consonants, so the audio does not segment the way the writing does. It is a listening problem and it responds to listening.

How long to become conversational in French?

Several months of consistent daily work for basic conversation. The FSI's 600 to 750 hours targets professional working proficiency, which is well beyond conversational.

Is French harder than Spanish?

Both are Category I. French pronunciation and listening are generally the harder of the two; the written language is comparably accessible.
