Kazakhstan dwarfs United States: about 2,712,747 km² km² against 9,439,424 km² km². At true size Kazakhstan is about 3.5× larger — the whole of United States fits into Kazakhstan roughly 3 times.
Kazakhstan sits in Asia, United States in North America. On the old Mercator map the latitude gap distorted how large each felt beside the other; at true size the answer is simply 3.5×.
The old Mercator map treated both about equally (2.3× vs 2× inflation), so at least their relative sizes were preserved — even if both were drawn at the wrong absolute scale.
Kazakhstan fits 3× into United States.
