Your eyes are indeed deceived; the fact that the
Mercator projection makes areas close to the poles look bigger is often illustrated by that many schoolchildren think that Greenland could give Africa a run for the money in the size compartment yet in real life Africa is vastly larger.
To illustrate this: zoom in somewhere on the equator on Google Maps(a map which uses the Mercator projection), drag yourself northwards and see how the scale in the lower right corner changes as you go further north.
