Canada has a surface area of 9.98 million and a volume of 349.46 mllion cubic kilometers while the Moon is a spherical entity with a surface area of 37.9 million square kilometers and a volume of 21.92 billion cubic kilometers. It only makes sense that the Moon would be bigger as it is spherical whilst Canada is a flat land mass.

For a more thorough look at each of these bodies below, continue reading as it will be covered in a lot more detail below.

How Big Is Canada?


Canada is one of the world’s largest countries, second only to the vast expanse of Russia. Still, with a population of just over 38 million, it remains one of the least densely populated countries, with more than 10 million people.

Canada has a total area of 9,984,670 sq. km, which encompasses its land mass and vast stretches of water. This country possesses an estimated 31,752 lakes, giving it the greatest number of lakes of any country in the world – they account for 9% of the country’s total surface area.

Without these, Canada would be smaller than both China and the US, possessing a land area of “just” 9,093,510 sq. km.

Canada has a width of 5,514km between its most extreme easterly point of Cape Spear across to the Yukon and Alaska boundaries. Its height – from Cape Columbia to Ontario – is 4,634km at its peak. And it has the longest coastline in the world, stretching over 240,000km. Canada is so big that the UK could fit inside it over 40 times.

Canada’s border with the USA is the longest in the world, with a length of 8,891km; this also holds the title for the longest undefended boundary in the world. In addition, the sheer size of Canada means that it borders three oceans: the Atlantic, the Pacific, and the Arctic. And from east to west, the country covers six time zones.

Roughly 24% of Canada’s total land area comprises mountains, with the tallest peak being Mount Logan which reaches a height of 5,959 meters. Still, the vast number of lakes reduces the average thickness of Earth’s crust. Scientists estimate that the thinnest strips of crust are around 29 km thick. But the average thickness is between 30 and 40 km.

If we take the average thickness to be 35 km and multiply it by the total surface area, we can calculate the estimated volume of Canada to be around 349,463,450 cubic km.

Canada’s diverse physical geography encompasses towering mountains, rolling plains, and expansive lakes. The Canadian Shield is a northern hilly region of swamps and lakes that contains some of the oldest rocks in the world. Further north, ice and snow dominate the landscape in the glacial Arctic regions.

How Big Is The Moon?

The moon has a surface area of 37,936,695 sq. km, which is about 4 times the area of Canada. While this celestial body may appear to be a perfect sphere, it is an oblate spheroid which means that the diameter is slightly less when you measure it pole to pole instead of across the equator.

The moon’s volume, when we look at its entire body, is 21,971,669,064 cubic kilometers. The crust is thicker than the Earth’s crust, which is pretty significant if you’re comparing the size of these two bodies. The moon’s crust is between 60 and 100 kilometers thick.

Even if we take the moon’s crust at its thinnest, the total area tops two billion cubic kilometers, which is still significantly bigger than the volume of the Canada.

Viewing the moon, you can see the mix of dark lunar plains and bright mountainous highlands. Early observations led scientists to believe that the dark areas could represent water, but we have since discovered that there is no water on this airless surface.

Earth mountains are created through tectonic or volcanic action. In comparison, the moon’s mountainous ranges formed almost exclusively from the impact of crater collisions.

There are three significant mountain ranges on the moon: the Montes Caucasus and Montes Apenninus create a barrier between the Sea of Serenity and the Sea of Showers. And in the northwest, the Plato crater is encased by the Montes Alpes (lunar Alps).


Canada may be the second biggest country on Earth but, being a flat land mass it isn’t anywhere close to the Moon in size. The only area it overtakes it is in diameter where Canada’s is 5,514km whereas the Moon’s is 3,474.8km.

In regards to surface area and volume, the moons surface area is about 4 times bigger and in regards to volume, the moon is roughly 220 times larger than Canada, making it far and away the larger body of the two.
