Nearly a tie: Argentina and Kazakhstan differ by barely 2% in area: about 2,780,400 km² against 2,724,910 km².
Argentina sits in South America, Kazakhstan in Asia. On the old Mercator map the latitude gap distorted how large each felt beside the other; at true size the answer is simply 1.02×.
The old map muddied it further: Mercator inflates Argentina about 1.5× and Kazakhstan about 2.3×, so on a Mercator-style map this pair appears 1.5× apart instead of the true 1.02×.
Kazakhstan fits 1× into Argentina.
