How big is the Earth?

Browse → Science → Our Planet
Have you ever heard somebody say “it’s a small world”? Well, here are some numbers to make you think again!

The circumference of the Earth is about 40,000 kilometers or 24,900 miles. This refers to how big the Earth is around it’s fattest middle part, like if you were to measure the length of a string going around the center of the Earth at the equator.  Because the Earth isn’t shaped like a perfectly round sphere or ball, it’s a little wider going around the equator than it is if you measure the circumference from top to bottom (like through the North and South Pole).

The total surface area of the Earth is about 500,000,000 square kilometers. “Surface area” refers to all of the area of the lands surface, such as oceans and continents. It’s sort of like the total amount of space on the Earth that you could walk on or swim through. It means that if you were going to gift-wrap the Earth like a present, you would need 500,000,000 square kilometers of wrapping paper!

    It’s a BIG world!

    Here are some other ways to think about the size of the Earth!

    The Earth has over six and a half billion people who live in about 200 different countries on seven different continents.

    If a person were able to drive all the way around the circumference of the earth going nonstop at highway speed (100kph or 62mph), it would take about 17 straight days to make it from beginning to end!

    If you were to lay down a bunch of shoelaces from end-to-end, you would need over 157 million laces that were each 10 inches long in order to make them go all the way around the circumference of the Earth!
