How to Memorise All the Countries of the World
· 6 min read
How long does it take to learn all the countries?
Most people can place every country on a world map in two to six weeks, practising 10 to 15 minutes a day. The variable is not talent but method: testing yourself daily on small regional sets beats staring at a complete world map for an hour once a week, by a wide margin.
The task is smaller than it looks. There are 196 countries under the common definition, but roughly 40 of them you already know, and another 60 come almost free once you have their neighbours.
Does testing yourself really work better than reviewing?
Yes. Retrieval practice — trying to recall an answer before checking it — produces substantially better long-term retention than re-reading or re-studying the same material. This is one of the most reproduced findings in cognitive psychology, established by Roediger and Karpicke's 2006 experiments and replicated many times since.
The counterintuitive part is that testing feels worse. Re-reading a labelled map feels smooth and productive; being asked "where is Burkina Faso?" and failing feels like failure. The struggle is the mechanism. A failed retrieval followed immediately by the correct answer builds a stronger memory than a comfortable review.
Practical consequence: spend most of your time on blank-map quizzes, not on labelled maps.
What is spaced repetition and how do I use it here?
Spaced repetition means reviewing material at increasing intervals rather than all at once. The spacing effect dates to Hermann Ebbinghaus in 1885 and is the basis of every flashcard system built since.
Applied to countries, a workable schedule looks like this:
| Day | What to do |
|---|---|
| 1 | Learn one region, then quiz it twice |
| 2 | Quiz yesterday's region, learn a new one |
| 4 | Re-quiz the first region |
| 7 | Re-quiz both |
| 14 | Mixed quiz across everything so far |
| 30 | Full world round |
The important detail is that intervals grow. Reviewing something you already know solidly is nearly wasted time; reviewing something just before you would have forgotten it is where the value sits.
What is the best order to learn the regions?
Learn in ascending order of difficulty, so each region borrows structure from the last. A sensible sequence:
- South America (12 countries). Small, distinctive shapes, one obvious spatial arrangement.
- North and Central America (23). Mostly familiar, plus the Caribbean to sort out.
- Europe (45). Many countries but strong shapes and familiar names. Do western Europe, then the Balkans, then the Baltics.
- Asia (48). Anchor on India, China and Russia, then fill in the Middle East, Central Asia and South East Asia.
- Africa (54). The hardest, so leave it until your method is working. Learn it in bands: north, Sahel, west, horn, central, south.
- Oceania (14). Australia and New Zealand, then the Pacific island groups.
Within a region, chunk into groups of five to nine. Working memory handles small sets far better than long lists, and a group of seven Balkan states is a single thing to remember rather than seven separate things.
What actually makes a country stick?
Attach each country to something other than its outline. Isolated shapes are almost impossible to retain; connected facts are easy.
- Neighbours. "Paraguay sits between Bolivia, Brazil and Argentina" gives four anchors at once.
- Coastline. Whether a country touches the sea, and which sea, halves the search space instantly.
- A distinguishing feature. "Chile is the long thin one", "Italy is the boot", "Norway has the fjord edge".
- Confusable pairs learned together. Never learn Slovakia without Slovenia in the same breath.
- The flag. Flags and shapes reinforce each other; learning both gives two routes to the same memory.
Only practise what you get wrong
After a round, restrict the next round to the countries you missed. This is the single highest-yield adjustment most people can make, and almost nobody does it — they replay the full set and spend 80% of their time on countries they already know.
Mappari offers "Practice missed" at the end of every round for exactly this reason, and the round covers every country you missed regardless of the length setting.
A concrete four-week plan
Week 1. South America and North America, 10 minutes a day. Finish the week able to place all 35.
Week 2. Europe, split into three chunks. Add a short re-quiz of week 1 every other day.
Week 3. Asia, anchored on the big three. Keep re-quizzing Europe.
Week 4. Africa in bands, plus Oceania. Finish with full world rounds, then switch to Blitz to build speed.
Start with South America, which takes about five minutes to learn and will convince you the rest is possible.
Put it into practice: try the world locate quiz or the flags quiz.
