Which is bigger: Monaco or San Marino?

Monaco is larger (74.9 km²) — about 1.2 times the size of San Marino (61 km²).

Why do Monaco and San Marino look different on the map than in reality?

The common Mercator projection enlarges areas the farther they lie from the equator, so the on-map size proportions of Monaco and San Marino are distorted compared to their true land area.
