For most adults, 20 to 60 minutes a day, almost every day, is a realistic starting point (a practical recommendation, not an official figure). Research doesn't set a number of hours, but it shows two things: spreading practice over several sessions improves retention and, for the same total hours, packing them into fewer weeks also helps. What works worst is one long class a week.
The right question isn't only "how many hours" but "how often" and "how". Ten minutes of real conversation are worth more than an hour of reviewing lists without speaking. That's why we recommend combining short daily sessions with role-play missions adapted to your level or English speaking practice at your level.
If your problem is finding the time, read how to improve your English speaking with little time. And if you already understand but can't speak, start with understand English but can't speak it?
How many hours a day should I study English?
There's no universal number: it depends on your goal, your level and the time you have. The evidence does support studying almost every day, in sessions you can keep up, and reviewing what you learned a few days later instead of repeating it all at once. If you can put in more hours per week, you'll progress faster; the key is not to pack everything into a single day.
As a reference for hours per level, Cambridge English estimates about 200 guided learning hours to move from one CEFR level to the next (for example, about 350–400 cumulative hours to reach B1). These are lesson and guided-study hours, not just conversation. What follows is based on published studies on how to spread that time.
What the research says
Spreading sessions out improves retention
The meta-analysis by Cepeda and colleagues (2006) pooled 839 assessments from 317 experiments on distributed practice. It found that the ideal gap between sessions depends on how long you want to remember something: the further away the test or conversation, the more it pays to space your review.
For second language learning, Kim and Webb (2022) analyzed 98 effect sizes from 48 experiments (3,411 participants). Spaced practice had a medium-to-large effect. Shorter gaps worked as well as longer ones on immediate tests, but worse on delayed tests.
And in real classrooms? Mawson and Kang (2025) screened over 3,000 articles and kept 22 reports of classroom studies (more than 3,000 learners). Distributed practice beat massed practice with a moderate effect (d = 0.54).
But intensity matters too
Here's an important nuance. Serrano and Muñoz (2007) compared adults in three English courses with the same 110 hours: an "extensive" one of 4 hours a week over seven months, a "semi-intensive" one of 8 to 10 hours a week, and an intensive one of 25 hours a week over five weeks. The results suggest that concentrating the hours in a shorter period was more beneficial than spreading them over many months.
And for oral grammar practice, Suzuki and DeKeyser (2017) found that massed practice reached the same accuracy as distributed practice, and possibly faster speech.
Do they contradict each other? Not really. A reasonable way to read them together: more hours per week and frequent practice help you progress, and coming back to what you learned days later helps you not forget it. What no study supports is one weekly class and nothing else.
| Study | What it compared | Main result |
|---|---|---|
| Cepeda et al. (2006)Meta-analysis | 839 assessments in 317 experiments | The best gap between sessions grows the longer you want to remember |
| Kim & Webb (2022)Meta-analysis, second languages | 48 experiments, 3,411 participants | Medium-to-large effect of spaced practice; longer gaps better in the long run |
| Mawson & Kang (2025)Meta-analysis, classrooms | 22 reports, 3,000+ learners | Distributed practice wins with d = 0.54 |
| Serrano & Muñoz (2007)Adults, English | 110 hours over 7 months, 3–4 months or 5 weeks | Concentrating the hours in less time was more beneficial |
| Suzuki & DeKeyser (2017)Oral grammar | Massed vs. distributed practice | Same accuracy; massed possibly faster |

How much time a day for your goal
These are HelloVozi's practical recommendations, not figures from a study. Adjust them to your level: if you don't know it, see our guide to CEFR levels from A1 to C2.
| Goal | Time per day | Days per week | How to split it |
|---|---|---|---|
| Maintain your level | 15–20 min | 5–6 | One speaking or active-listening session + quick vocabulary review |
| Make steady progress | 30–60 min | 5–6 | 2 blocks: input (listening or reading) and output (speaking or writing) |
| Prepare for an exam or interview | 1–2 h | 6 | Practice the real task + spaced review of your mistakes |
| Start from scratch | 20–30 min | 6–7 | Useful phrases, audio with transcript and speaking out loud from day one |

Microlearning: making short sessions count
Microlearning means short lessons of a few minutes focused on a single goal. It fits real life: hardly anyone has an uninterrupted free hour every day, but most people have several five- or ten-minute gaps. Brevity alone isn't enough, though. It works when it meets three conditions:
- It's frequent and consistent. Ten minutes every day adds up to more than an hour on a Sunday. In Foote and McDonough's (2017) shadowing study, 10-minute sessions at least 4 times a week for 8 weeks were enough to improve comprehensibility and fluency.
- It makes you recall. Roediger and Karpicke (2006) showed that trying to remember (testing yourself) leads to better retention a few days later than restudying the same material, even though restudying feels more reassuring. In English: say the sentence from memory before you look at it.
- It revisits earlier material. Each short session should review something from a few days ago, not just move on to new content.
Short sessions have a limit: to speak fluently you also need somewhat longer conversation blocks where you hold an idea for several minutes. In de Jong and Perfetti's (2011) study, for example, learners who repeated the same talk in 4, 3 and 2 minutes kept their fluency gains. Combine both formats.
Sample schedules
| Profile | Monday to Friday | Weekend | Approximate total |
|---|---|---|---|
| Little time | 15 min: 5 review + 10 conversation | Saturday 30 min of input (series or podcast) | ≈ 1 h 45 min |
| Some time | 35 min: 15 input + 20 speaking | Saturday 45 min, Sunday rest or review | ≈ 3 h 40 min |
| Intensive | 1 h 30 min: input, applied grammar and 30 of conversation | Saturday 1 h of exam-style practice | ≈ 8 h 30 min |
Schedules suggested by HelloVozi. What matters is regularity and reviewing what you learned days later.
Common time-planning mistakes
- Waiting for "a free hour". If it never comes, you never practice. Start with 10 minutes.
- Only new content. Without spaced review you forget earlier material. Spend part of each session on something from days ago.
- Counting hours instead of practice. An hour with your phone beside you and no speaking isn't an hour of English.
- Never speaking. Input time is essential, but if you never produce, your speaking won't grow at the same pace.
- Leaving it all for the weekend. It's the format that comes out worst in every study above.

Frequently asked questions
How many hours a day should I study English?
There's no official number. As a starting point, 20 to 60 minutes almost every day is realistic for most adults. If you have a near goal, like an exam, you can go up to 1 or 2 hours split into blocks.
Is it better to study a little every day or a lot once a week?
A little every day. The meta-analyses by Cepeda et al. (2006), Kim and Webb (2022) and Mawson and Kang (2025) show that spreading practice out improves retention compared with packing it into one session.
Is 15 minutes a day enough to learn English?
It's enough to keep the habit and progress little by little, especially if it includes speaking and review. To move faster, add a longer block or two during the week.
What is microlearning and does it work for English?
It's short lessons focused on a single goal. It works if it's frequent, makes you recall and reviews earlier material. On its own it doesn't replace the longer conversations you need to build fluency.
Can you learn English fast?
You can progress faster with more hours per week: in Serrano and Muñoz's (2007) study, packing the hours into fewer weeks was more beneficial. But there are no shortcuts to a high level: it takes consistent practice over months.
How many hours does it take to move up a level?
It depends on the person, the starting point and the quality of practice. As a guide, Cambridge English estimates about 200 guided learning hours to move from one level to the next.
