It's one of the most common questions learners ask — and one of the hardest to answer honestly, because "how long to learn English" depends heavily on your starting point, your first language, and how consistently you study. Still, there are useful, evidence-based estimates worth knowing.
Where these estimates come from
Language schools and testing organisations have long tracked roughly how many hours of focused instruction it typically takes to move between CEFR levels. These numbers assume structured study (not just casual exposure), and they vary by how closely your first language relates to English — a Spanish speaker will generally progress faster through English grammar than a speaker of a language with a very different structure, simply because of shared vocabulary and grammatical patterns.
Estimated hours by CEFR level
| Level | Approximate hours (from previous level) | Approximate cumulative hours |
|---|---|---|
| A1 (Beginner) | 90–100 hours | 90–100 |
| A2 (Elementary) | 150–180 hours | 240–280 |
| B1 (Intermediate) | 200–250 hours | 440–530 |
| B2 (Upper-Intermediate) | 250–300 hours | 690–830 |
| C1 (Advanced) | 250–300 hours | 940–1,130 |
| C2 (Mastery) | 200–300 hours | 1,140–1,430 |
Notice that each level generally takes more hours than the one before it, even though the CEFR levels look evenly spaced on paper. That's because the amount of language knowledge needed to notice a meaningful improvement grows at higher levels — the gap between A1 and A2 is much smaller in absolute terms than the gap between B2 and C1.
Why your first language changes the timeline significantly
The U.S. Foreign Service Institute's well-known language-difficulty rankings (originally built for English speakers learning other languages, but broadly informative in reverse too) place languages into difficulty categories based on structural similarity. If your first language shares an alphabet, vocabulary roots, or grammatical patterns with English — as with most European languages — you'll likely move faster than someone whose first language differs greatly in script, sentence structure, or sound system.
Factors that speed things up
- Consistency over intensity: 30 focused minutes daily consistently outperforms one long weekly session, because language learning relies heavily on spaced repetition and habit formation.
- Active production, not just passive input: speaking and writing regularly — not just reading and listening — accelerates real fluency, since production forces retrieval, which strengthens memory more than recognition alone.
- Immersion, even partial: switching your phone's language, watching shows in English with English subtitles, or thinking in English during routine tasks all add "hidden" practice hours beyond formal study.
- Targeted practice on weak areas: generic study is less efficient than identifying and drilling your specific recurring mistakes — see our common mistakes guide for a systematic approach.
Factors that slow things down
- Inconsistent study (long gaps between sessions lose momentum and require re-learning)
- Studying only grammar rules without applying them in real sentences or conversation
- Avoiding speaking practice out of fear of mistakes — see our speaking skills guide for how to push past this
- Plateaus, which are a normal part of every level and don't mean progress has stopped — they usually mean deeper, less visible consolidation is happening
A more useful question than "how long"
Rather than fixating on a total timeline, it's often more motivating — and more accurate — to ask "what does the next level actually require?" Our English Levels section breaks down exactly what each CEFR level involves in vocabulary, grammar, and skills, so you can focus on concrete, achievable next steps rather than an abstract finish line.
