Land area: The US is 27% larger than Australia
Australia has a land area of approximately 7,741,220 square kilometres. In comparison, the United States boasts a larger land mass of roughly 9,833,517 square kilometres. This makes the US approximately 27% bigger than Australia in terms of land area.
To put this into perspective, consider that the extra 27% of land area in the US is equivalent to more than a quarter of Australia's total land mass. This significant difference in size becomes evident when examining the individual states that comprise each country.
For instance, the state of Alaska in the US, with a land area of approximately 1,518,800 square kilometres, already surpasses the entire land area of Australia by almost 10%. Additionally, the contiguous US states, excluding Alaska and Hawaii, collectively cover a larger area than Australia.
The disparity in size is further accentuated when comparing the respective populations of the two countries. The US accommodates approximately 311.2 million people, significantly outnumbering Australia's population of around 26.1 million. This indicates that the US not only possesses a larger land area but also supports a substantially higher population.
In summary, the land area of the United States is approximately 27% larger than that of Australia. This substantial difference in size becomes apparent when comparing individual states and population numbers, highlighting the geographic and demographic variations between these two countries.

Population: 311.2 million more people live in the US
When comparing the sizes of the United States and Australia, it is evident that the US has a significantly larger population. With approximately 311.2 million more people, the US population surpasses that of Australia. To put this into perspective, the entire population of Australia is similar to the population of a single US state, such as Texas, which has around 30 million people.
The population disparity between the two countries is quite substantial. The US has a total population of roughly 301,000,000 million people, while Australia's population is significantly smaller at approximately 26.1 million people. This means that the US has more than triple the number of residents compared to Australia.
The impact of this population difference is noteworthy. From an infrastructure standpoint, Australia's travel industry faces challenges in matching the frequency of transportation services offered in the US. The lower population density in Australia affects the feasibility of maintaining the same level of connectivity and convenience in travel options as seen in the US. This underscores the importance of careful trip planning when visiting Australia to avoid potential issues with connections and travel times.
The population concentration in the US allows for a more extensive and frequent transportation network, offering greater flexibility and convenience for travellers. In contrast, Australia's smaller population results in a less dense distribution, necessitating careful consideration of travel logistics to ensure a smooth and well-connected journey.
The vast population difference between the United States and Australia, with the US boasting a substantially larger population, has a direct impact on the travel experience and infrastructure within each country. The US benefits from its population size, offering a more comprehensive transportation network, while Australia, with its smaller population, requires more mindful trip planning to navigate potential limitations in travel options.

Mercator projection: This distorts size near the poles
The Mercator projection is a conformal cylindrical map projection that was first introduced by Flemish geographer and cartographer Gerardus Mercator in 1569. It became the standard map projection for navigation in the 18th century due to its ability to represent rhumb lines or loxodromes as straight lines, making it ideal for marine navigation.
However, one of the primary criticisms of the Mercator projection is its distortion of land areas, particularly near the poles. This distortion occurs because circles of latitude on Earth decrease in size as they approach the poles, but they are stretched in an East-West direction on cylindrical map projections to maintain a uniform length. The Mercator projection uniquely combines this East-West stretching with a corresponding North-South stretching, resulting in local scale uniformity and preserved angles at every location.
Consequently, the Mercator projection inflates the size of lands farther from the equator. For example, Greenland and Antarctica appear much larger on Mercator maps than they are in reality relative to landmasses closer to the equator. This distortion has led critics like George Kellaway and Irving Fisher to argue that the projection is unsuitable for general world maps, as it can influence people's perceptions of different regions' importance.
While the Mercator projection is still commonly used for areas near the equator, where distortion is minimal, and in maps of time zones, other projections like the Gall-Peters projection have been proposed to address the distortion issues associated with Mercator maps. Additionally, specific projections like the Universal Transverse Mercator (UTM) and Universal Polar Stereographic (UPS) are recommended for latitudes between 84°N and 80°S and polar regions, respectively.

Comparison methods: Use outlines to reposition for scale
To compare the size of the United States and Australia, one can use outlines to reposition the countries and gain a better understanding of their relative sizes. This method involves superimposing the outlines of the two countries on a map, allowing for a direct visual comparison.
When using outlines to reposition for scale, it is important to ensure that the maps or outlines are to scale. This means that the shapes and sizes of the countries are accurately represented. One popular map projection that can be used for this comparison is the Mercator projection, which is often used for navigational purposes and can provide a relatively accurate representation of the countries' sizes. However, it is important to note that the Mercator projection does distort the size of regions near the poles, which can affect the accuracy of the comparison near the northern or southern extremities of the countries.
By superimposing the outlines of the United States and Australia, one can visually appreciate the differences in their sizes. The United States, with an area of approximately 9,833,517 square kilometres, is larger than Australia, which has an area of approximately 7,741,220 square kilometres. The United States is, in fact, around 27% larger than Australia when considering their landmasses.
This comparison method can be particularly useful when trying to understand the relative sizes of countries that are distant from each other, such as the United States and Australia. By repositioning the outlines, one can imagine overlapping the countries in a different configuration, bringing them closer together on the map. This can aid in visualising how much larger one country is compared to the other.
Additionally, by using outlines, one can also compare the overall shapes of the countries and how their landmasses are distributed. For example, the United States has a more elongated shape, stretching across multiple time zones, while Australia is wider and more compact in comparison. These visual cues can provide a more comprehensive understanding of the countries' sizes and geometries, complementing the quantitative data on their areas.

Size in context: Australia is still quite large
With a total land area of approximately 9.8 million square kilometres, Australia is indeed the smaller country when compared to the United States, which boasts a land area of about 9.9 million square kilometres. However, it's important to remember that Australia is still an extensive and spacious country in its own right. To put things into perspective, let's consider some comparative analyses.
Australia is comparable in size to mainland China, which is slightly larger at 9.6 million square kilometres. This makes Australia the sixth-largest country by area, with a vast interior that includes a variety of landscapes, from dense forests to arid deserts. In contrast, the United States, with its famous diversity of regions and environments, is roughly comparable in size to the entire continent of Europe, excluding Russia.
Another way to conceptualize Australia's size is to think of it in relation to other countries or territories. For instance, Australia is about 50 times bigger than the United Kingdom, and if you were to place Australia over a map of the United States, the continent would cover the mainland US, stretching from the west coast to the east, and from Canada in the north down to Mexico in the south. In fact, Australia is so large that it actually constitutes one of Earth's seven continents, often referred to as "Australia, the continent country."
Despite being smaller in land area, Australia has a much smaller population than the United States, with around 26 million people compared to over 331 million. This means that Australia has a much lower population density, offering a sense of spaciousness and a different relationship to the environment than many other countries. So, while the United States may surpass Australia in sheer geographical size, Australia remains an impressively large and geographically diverse country on the world stage.
