Remembering capitals and flags: methods and exercises
By Lorenzo Geano · Updated on November 2, 2026 · 4 min read
The link between a country and its capital is far from obvious: nothing in the name of a country leads to the city. Flags demand the same memory effort, with colours and shapes to recognise. This article proposes a method in several steps: learn in small groups, rely on the map, group flags into families, then test yourself and space out your revision.
Why capitals are hard to remember
The link between a country and its capital is arbitrary, and some cities are easily confused. The capital of Australia is Canberra, not Sydney, which people often confuse with it. Canada's is Ottawa, Brazil's is Brasília, Turkey's is Ankara and New Zealand's is Wellington.
A well-known city can thus make you forget the capital. It is useful to write these pairs in a separate list and review them more often than the others.
Working in small groups
Learning all 193 countries at once is heavy. It is more effective to work by continent, then by region, in short sessions. This method respects the limits of working memory, which holds only a few items at a time, about four chunks (Cowan, 2001). Grouping information into chunks therefore prevents it from overloading memory.
The country profiles (193 countries) give the capital, flag, map, neighbours, languages, currency and area of each country: a good starting point for a small group.
Using the map to locate
A capital is easier to remember when you know where it is. The place the capitals on the map game asks you to locate each city on the world. The geography games go further: you name a place, click on a country, zoom in and move around the map to get your bearings.
Flags by family
A flag is easier to remember when compared with its family neighbours than on its own. A few families help a great deal:
Nordic crosses: Denmark, Sweden, Norway, Finland and Iceland.
Tricolours with vertical stripes: France, Italy and Ireland.
Reversed two-colour flags: Indonesia (red above white) and Poland (white above red).
For each flag, describe its colours and their arrangement, then check in the flag games.
Testing yourself and spacing out revision
Testing and spacing are the two techniques that the review by Dunlosky et al. (2013) rates as having high utility. On Mnemoz, you can name all the capitals within the time allowed, or all the flags. You choose the number of questions (10, 20, 50 or all those in the area), then the area: a continent or the whole world.
Spacing means returning to the same countries several days apart, rather than seeing everything in a single session. Cepeda et al. (2006) find that a study spread over time improves retention compared with a single block. For details, see spaced repetition and the testing effect.
For the flags, the “name all the flags” mode requires you to produce the name, whereas “recognise a flag” and “pick the right flag” require you to recognise it. Starting with recognition, then moving on to naming, lets you increase the difficulty step by step.
A four-week plan, as an example
This plan is only an example, not a rule. It assumes short sessions, several times a week:
Week 1: Europe and North America, in small groups, with the map.
Week 2: Asia and Oceania, placing the capitals on the map.
Week 3: Africa and South America, with the flags grouped by family.
Week 4: mixed revision, with a set of 20 or 50 questions.
Each week, finish with a test without help, then go back to the countries you missed the following week.
Frequently asked questions
How many capitals should I learn each day?
There is no ideal number, and this article gives none. What matters is how the study is spread: spread-out study is better than one single block (Cepeda et al., 2006). On Mnemoz, choosing 10, 20, 50 or all the questions lets you adapt the session to the time you have.
Where should I start?
Start with a small group of countries you already know a little, for example a single continent. Then add one group at a time, in short sessions. Once the group is familiar, move on to the place the capitals on the map game to locate it, then to the capitals to name.
What about countries that have several capitals?
Some countries have more than one city that acts as a capital. To keep track, note the exact wording of the question and the expected answer, then read the explanation that follows each answer on Mnemoz. The profile of each country, in the country profiles (193 countries), also lets you check which capital is used.
