Why do San Marino and Tuvalu 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.
