Spaced Repetition for Beginners: A Simple Setup That Sticks
Spaced repetition for beginners comes down to one rule: review something just as you are about to forget it, and each time you remember it, wait longer before the next review. A simple starting schedule is 1 day, 3 days, 7 days, 16 days, then about a month. You can run it with a free app like Anki or with a shoebox of index cards.
This guide shows both versions, a first-week plan, and the mistakes that make most beginners quit by week three.
How spaced repetition works
In the 1880s the psychologist Hermann Ebbinghaus tested his own memory of nonsense syllables and found that forgetting is fast at first, then slows. That pattern is now called the forgetting curve. The useful part is the second finding: each well-timed review flattens the curve, so the memory lasts longer before it fades again.
Two things do the work. The spacing means reviews are spread out rather than crammed. The retrieval means you try to recall the answer before you see it. Rereading a card’s answer side does very little. Struggling for two seconds to pull it out of memory is what strengthens it. This is the same principle behind active recall, and spaced repetition is really active recall on a timer.
If you want the background on why memories fade in the first place, our explainer on why you forget what you learn covers it in plain terms.
What spaced repetition is good for (and not)
It shines for discrete facts you need on instant recall:
- Vocabulary when you learn a language as an adult
- Names, dates, definitions, formulas
- Chords, scales or chess openings
- Key ideas from a book you want to keep
It is weak for skills that need doing, like writing code or cooking a dish. Cards can support those skills, for example remembering a function name, but they cannot replace practice.
Before you start: app or paper?
| Anki (app) | Paper (Leitner box) | |
|---|---|---|
| Cost | Free on desktop and Android; paid on iPhone | Index cards and a box |
| Scheduling | Automatic | You move cards between boxes |
| Setup time | 20 to 30 minutes to learn the basics | 5 minutes |
| Best for | Large decks, years of use | Fewer than 200 cards, people who dislike screens |
| Main risk | Fiddling with settings instead of studying | Forgetting which box is due |
Anki is the standard free tool and its default settings are fine for beginners. Leave them alone for the first month.
Step by step: your first setup
The app version
- Install Anki and create one deck named after your topic. One deck, not ten.
- Write 10 cards, no more. Each card asks one question with one short answer.
- Set new cards per day to 10. The default of 20 is too many for most beginners.
- Study once a day. Anki shows due cards; answer honestly with Again, Hard, Good or Easy.
- Add 5 to 10 new cards a day only while your daily reviews stay under about 15 minutes.
The paper version (Leitner system)
- Label five boxes or envelopes: Every day, Every 2 days, Every 4 days, Weekly, Every 2 weeks.
- Put all new cards in Box 1.
- When you answer a card correctly, move it up one box. When you miss it, it goes back to Box 1, no matter where it was.
- Keep a sticky note on the lid with which boxes are due each day.
How to write cards that stick
Bad cards are the main reason beginners give up. A bad card is slow, vague and painful to review.
- One fact per card. “What are the causes of World War I?” is a bad card. “What 1914 event in Sarajevo triggered World War I?” is a good one.
- Write it in your own words. Copying a textbook sentence means you are memorizing wording, not meaning.
- Add context cues. For vocabulary, put the word in a short sentence rather than alone.
- Make it two-way when it matters. For a language, you want both “dog to perro” and “perro to dog”.
- Only card what you understand. Memorizing something you do not understand is fragile. Learn it first, then card it.
The 10-second test: if you cannot answer a card in about 10 seconds when you know it, the card is too big. Split it.
Your first week
| Day | New cards | Reviews (rough) | Total time |
|---|---|---|---|
| 1 | 10 | 0 | 10 min (includes writing cards) |
| 2 | 10 | about 10 | 10 min |
| 3 | 10 | about 15 | 10 to 12 min |
| 4 | 5 | about 20 | 10 to 12 min |
| 5 | 5 | about 20 | 10 min |
| 6 | 0 | about 20 | 8 min |
| 7 | 0 | clear the due pile | 5 to 10 min |
The numbers are approximate, but the shape matters: reviews grow as you add cards, so you slow new cards before reviews take over your day. A good long-term rule is that every new card you add today creates about ten reviews over the coming months.
Example cards for three kinds of learner
Seeing good cards side by side makes the rules above concrete. Say you are working on three different things this year.
| Topic | Front | Back |
|---|---|---|
| Spanish | “Can you pass me the ___?” (salt) | la sal: “¿Me pasas la sal?” |
| Guitar | Which three notes make a G major chord? | G, B, D |
| A history book | Which document did King John agree to at Runnymede in 1215? | Magna Carta |
| Work skill | Excel function that returns a value from a matching row in another table (newer versions) | XLOOKUP |
Notice that each one has a single, short answer and a cue that points to it. None of them asks you to list five things or explain a whole theory. If you want to keep bigger ideas, break them into several small cards, each testing one link in the chain.
A useful habit is to write cards at the end of a study session, not during it. You will choose the facts that actually mattered instead of carding every sentence.
Common mistakes and how to avoid them
- Adding too many new cards. It feels productive on day one and becomes a 300-card backlog by day twenty. Cap new cards and protect the review time.
- Pressing “Good” when you half knew it. Being honest makes the schedule work. Lying to the app only moves forgetting into the future.
- Using shared decks for everything. Pre-made decks are handy for languages, but cards you write yourself stick better because writing them is itself learning.
- Skipping days and then quitting. Missing a few days creates a pile. The fix is below, not deleting the deck.
How to know it is working
Expect the first two weeks to feel slow. Around week three you should notice that cards from week one come back easily and their review gaps are now a week or more apart. Anki shows this in its statistics: if most mature cards are answered correctly, you are fine. On paper, the sign is that the higher boxes fill up while Box 1 shrinks.
A more honest test: once a week, without cards, try to use what you learned. Say five words in a sentence, explain a formula, or name the chords in a song. Recall in real use is the goal, not a green bar.
Keeping it going when life gets busy
Everyone falls behind. When you do, stop adding new cards entirely until the backlog is clear. Then do 50 reviews a day, oldest first, until you are caught up. Most backlogs clear within a week. Our guide on getting back on track after a break has a fuller restart plan.
The minimum viable habit is five minutes of reviews on your phone while the kettle boils. On rough weeks, that keeps the schedule alive.
Where to go next
Write ten cards today on something you genuinely want to remember, and review them tomorrow morning. Once the habit holds for two weeks, look at how spaced repetition fits with other techniques in our overview of study methods that actually work for adults.
Frequently asked questions
What is the best spaced repetition schedule for beginners?
A simple schedule is to review after 1 day, 3 days, 7 days, 16 days and then about 35 days, extending the gap each time you remember. Apps like Anki calculate this automatically based on how well you answer. On paper, the Leitner box system approximates it by moving correct cards to less frequent boxes and missed cards back to daily review.
Can you do spaced repetition without Anki?
Yes. The Leitner system uses index cards and five boxes reviewed at increasing intervals. Correct cards move up a box, missed cards return to the first box. It works well for a few hundred cards. Other apps such as RemNote, Mochi or Quizlet's learn modes also use spacing, though Anki remains the most widely used free option.
How many new cards a day should a beginner add?
Five to ten new cards a day is a sensible start. Each new card creates several reviews in the following weeks, so a high number quickly turns into a backlog. If daily reviews take more than about 15 to 20 minutes, pause new cards until they come back down.
How long does it take to see results with spaced repetition?
You will notice older cards coming back easily within two to three weeks. Real long-term retention shows after one to three months, when cards reach intervals of several weeks and you still recall them. Results depend heavily on card quality, so short, clear cards show progress faster.
Can you do spaced repetition in 15 minutes a day?
Yes, and that is a good target. Fifteen minutes covers roughly 75 to 150 short reviews plus a few new cards for most people. Keep it there by capping new cards. Spaced repetition works because of consistency, so 15 minutes daily is better than an hour on Sundays.
What happens if I miss a few days of spaced repetition?
Cards pile up, and some will have been forgotten, but nothing is ruined. Stop adding new cards, then clear the backlog in daily chunks of about 50 reviews, oldest first. Most people catch up within a week. Avoid resetting or deleting the deck, since much of what you learned is still there.
Does spaced repetition work for adults over 40?
Yes. The spacing effect has been shown across age groups, and adults often benefit more because they have less study time and need it to count. If recall feels slower, use shorter cards, add context or images, and keep sessions short. Health factors like sleep also affect memory, so speak to a doctor if you notice sudden changes.
