How Big Is Alaska Compared to Australia: A Detailed Comparison

Understanding the sheer size of geographical locations can be challenging. This is where COMPARE.EDU.VN steps in, offering detailed comparisons that bring clarity and insight. Let’s delve into a comprehensive analysis of Alaska and Australia, providing you with a clear understanding of their sizes, geographical features, and other essential aspects for well-informed decisions.

1. Understanding the Scope: Alaska vs. Australia Size Comparison

When asking, “How Big Is Alaska Compared To Australia,” it’s essential to grasp the sheer scale of both regions. Australia is a continent and a country, covering a vast area, while Alaska, though a large state in the United States, is significantly smaller. Let’s break down the numbers to provide a clear perspective.

1.1. Area of Alaska

Alaska spans approximately 665,384 square miles (1,723,337 square kilometers). This massive expanse makes it the largest state in the U.S., exceeding even Texas by a considerable margin. However, its vastness is often hard to fathom without a direct comparison.

1.2. Area of Australia

Australia, on the other hand, covers an area of about 2.97 million square miles (7.69 million square kilometers). This makes Australia nearly 4.5 times larger than Alaska. To visualize this, imagine fitting roughly four and a half Alaskas within the borders of Australia.

1.3. Population Density: A Key Differentiator

Size alone doesn’t tell the whole story. Population density further illustrates the differences between Alaska and Australia.

Alaska: With a population of around 733,000 people, Alaska has one of the lowest population densities in the world, at approximately 1.3 people per square mile.
Australia: Australia has a population of over 25 million people, resulting in a population density of about 8.5 people per square mile.

The vast difference in population density means that while Alaska offers unparalleled wilderness and solitude, Australia has more urban centers and developed areas.
