Against the lower 48

Laid over the lower 48 states, Alaska covers about a fifth of them. On most web maps it looks far bigger than that, because the Mercator projection stretches everything near the poles.

Across the date line

Its Aleutian Islands run so far west that they cross the 180th meridian, which makes Alaska both the westernmost and the easternmost state. It also has more coastline than all the other states together.
