20 centimeters is about the length of a small toy car or a ruler you might use at school.
Centimeters are a way to measure how long something is. Imagine you have a strip of paper, and you divide it into 10 equal parts, each part is 1 centimeter. So, if you put together 20 of those little parts, that’s 20 centimeters.
Like a Big Hand Span
If you stretch your hand out from your wrist to the tip of your middle finger, that's about 20 centimeters! It’s like having two of your hands side by side, but just one hand doing the job.
Compare to Something You Know
Think of a standard ruler, it’s usually 30 centimeters long. So 20 centimeters is most of that ruler, like from the start to where the number “20” is written. It’s also about how tall a small book might be, or the width of a big plate.
Next time you see something that's 20 centimeters long, you can imagine it as almost your whole hand, and that makes measuring fun!
Examples
