How Maps Work (For Kids)
⏱ 7 min read
A map is like a picture of a place seen from above. It shrinks down a huge area — a city, a country, the whole world — onto a piece of paper or a screen so you can hold it in your hands. Once you know how to read one, a map is one of the most powerful tools in the world: it can tell you where you are, where to go, and what to expect when you get there.
Symbols and the key
Maps use little pictures called symbols to stand for real things. A small tent might mean a campsite, a cross might mean a church, and a tiny aeroplane might mean an airport. Because no one would remember every single symbol, every map comes with a 'key' (sometimes called a 'legend'). The key is a little chart that tells you what each symbol means.
Scale: shrinking the world
Real countries are far too big to fit on paper, so map-makers shrink everything down using a 'scale'. A scale tells you how much smaller the map is than the real world. A scale bar might show you that 1 centimetre on the map equals 1 kilometre in real life.
Some maps zoom in on a small area like a town and show lots of detail. Others zoom out to show a whole continent and only show big things like cities and rivers.
The compass rose
Most maps have a little decorated arrow somewhere on them called a compass rose. It points to north. Once you know which way is north, you can also work out south (the opposite direction), east (to the right of north) and west (to the left). A handy way to remember the order going clockwise is 'Never Eat Soggy Waffles': North, East, South, West.
Latitude and longitude
If you look at a globe, you will see lines drawn on it. The lines that run side to side (like belts around the planet) are called latitude. The most famous one is the equator — the line that goes around the middle of the Earth. The lines that run from top to bottom (from the North Pole to the South Pole) are called longitude.
Together, latitude and longitude make a giant grid that lets you point to any spot on Earth using two numbers. The Eiffel Tower in Paris, for example, is at about 48° North, 2° East.
Different kinds of maps
There are lots of different kinds of maps for different jobs:
• A political map shows countries, capitals and borders. Each country is usually a different colour.
• A physical map shows mountains, rivers, deserts and forests. Greens and browns show how high or low the land is.
• A climate map shows weather and temperatures around the world.
• A road map shows you how to drive between places.
• A topographic map uses curvy lines (called contour lines) to show exactly how hilly the land is.
Why maps are sometimes 'wrong'
The Earth is round, and a map is flat. When you flatten a round thing, something always has to stretch or shrink. That means every world map has a little bit of distortion. The most famous version, called the Mercator map, makes countries near the poles (like Greenland) look much, much bigger than they really are. Africa is about 14 times bigger than Greenland — but on many maps they look about the same size!
Try it yourself
The best way to learn maps is to use them. Try drawing a map of your bedroom from above. Add symbols for your bed, your desk, your toys. Add a key. Add a scale (maybe 1 centimetre = 50 centimetres). Add a compass rose if you know where north is. Suddenly you are a map-maker!
Once you can read a map, the whole world opens up. You can plan adventures, follow walks in the countryside, find treasure (well, almost), and understand the news from anywhere on Earth. So grab a map and start exploring!
