Which is bigger: United States or Australia?
The United States is larger: 9,833,517 km² versus 7,692,024 km² for Australia, or about 28% more.
Both areas at the same scale: United States and Australia. Drag the outlines, separate them and see what the Mercator map hides.

What the map gets wrong
True area tells a different story than the Mercator map.
True area ratio1.3×Larger in reality: United States.
How it looks on Mercator2.1×Looks larger on a Mercator map: United States.
Why does this happen?
The Mercator projection enlarges areas more and more the farther they lie from the equator. The centers of the two areas lie about 45° (United States) and 26° (Australia) from the equator. On a Mercator map their area ratio is 2.1 : 1, while in reality it is 1.3 : 1.

Why do the United States and Australia look different on a Mercator map than in reality?
The Mercator projection preserves angles, which makes it useful for navigation, but it enlarges areas more and more the farther they lie from the equator. At 60° latitude, areas already appear four times larger than at the equator. A same-scale comparison like the one on this page greatly reduces that distortion.
