Country and Capital Matching Generator

What this generator does

Builds a matching exercise: a shuffled column of countries and a shuffled column of capitals, plus the answer key. Every capital in the set is distinct, which is what stops a row having two defensible answers — the usual failure of hand-made matching sheets, where two countries with the same city name make one row unmarkable.

How to use this tool

1. Choose how many pairs you want and whether to limit them to one continent.
2. Press Generate.
3. Print the sheet, or copy the two shuffled columns into your own worksheet.
4. Reveal the answer key when you are ready to mark.

Understanding the controls

Number of pairs

How many rows the sheet has. Under six is trivially solved by elimination alone; above about fifteen the columns get hard to scan on one page.

Continent

Restricting to one continent makes the exercise harder rather than easier: distractors are geographically close, so the pairs cannot be guessed by region.

Seed

Reproduces the identical sheet, so a class can all work the same one or a lost copy can be reprinted with the same answer key.

Worked examples

Ten pairs, mixed

Peru, Norway, Japan, Ghana… against Lima, Oslo, Tokyo, Accra…

One continent

Restricted to Africa, so 'somewhere in Europe' does not narrow anything.

Reprintable

The seed 'year-7-autumn' gives the same sheet and the same key.

Why capitals are unique here

Two countries whose capital shares a name would leave one row with two right answers.

Common use cases

• Geography starters and homework sheets
• Revision where recall alone is too hard and multiple choice too easy
• Cover lessons that need something printable and self-explanatory
• Quiz rounds where teams work a grid rather than answer in turn

How this generator works

Countries are drawn from a curated set in which every capital is unique and every entry has a single undisputed capital. Duplicated right-hand values are dropped before the sheet is built, because a repeated capital would make one row unanswerable and its answer key wrong. The two columns are then shuffled independently, and the key is derived from the pairing rather than from either column's order.

Randomness and fairness

The pairs and both column orders are drawn with the browser's cryptographic random number generator. A seed switches to a reproducible generator so the same sheet can be printed twice; that mode is deterministic, not cryptographic.

For how randomness is produced across the whole site, see how Generate Random works.

Assumptions this tool makes

• Each country in the set has exactly one capital, which is why the ambiguous cases are left out.
• Students match one-to-one, so every country has exactly one capital in the right-hand column and vice versa.

Limitations and good to know

• Countries whose capital is disputed or split are excluded rather than assigned one — South Africa has three by design, Bolivia's constitutional capital and seat of government differ. The full excluded list and the reasons are shown on the page.
• This is a curated set of widely recognised sovereign states, not every country. Which territories count as countries is contested, and a worksheet is the wrong place to settle it.
• Continent assignment is a convention. Russia, Turkey, Egypt and Kazakhstan span two, and are placed by where most of their population lives.
• It generates the sheet, not the marking. There is no answer entry — the key is for a person to mark against.

Common mistakes

Using very small sets for a test

Six pairs can be finished by elimination from two known answers. Ten or more before it measures much.

Assuming a missing country is an oversight

Countries with more than one capital are excluded deliberately and the reasons are listed. Marking 'Pretoria' wrong would test which source a sheet used rather than geography.

Mixing continents when you want difficulty

A mixed sheet is easier — region narrows the options. Restrict to one continent to make it genuinely harder.

Practical tips

• Print two different seeds for adjacent desks. Same difficulty, different sheets.
• Ask for the reasoning on the last two rows. Those are the ones solved by elimination, and the reasoning is the part worth hearing.
• Give the excluded-countries list to older students as a discussion point — 'why can this not be asked' is a better question than most on the sheet.

Troubleshooting

Not enough pairs came back

A single continent has a limited number of entries. Reduce the pair count or allow all continents.

A country I expected is missing

Check the excluded list on this page. It is almost certainly one whose capital has more than one defensible answer.

Privacy and your data

Nothing is entered and nothing is stored. Sheets are generated in your browser, never uploaded and never written into the page address. Analytics records only that the tool ran and how many pairs were asked for.

Frequently asked questions

Why is South Africa not included?

It has three capitals by constitutional design — Pretoria, Cape Town and Bloemfontein. A matching sheet needs one answer per row, so rather than pick one and mark the others wrong, countries like this are excluded and the reason is published.

Where does the data come from?

ISO 3166-1 for the country codes, and standard reference geography for capitals and continents, curated by hand for this catalogue and reviewed on the date shown on the page. Currency is deliberately excluded because countries change it and a stale answer is worse than a missing one.

Can I get the same sheet again?

Yes — enter a seed. The same seed always produces the same pairs, the same column order and the same key.
