Canada dwarfs Saudi Arabia: about 9,872,102 km² km² against 1,925,871 km² km². At true size Canada is about 5.1× larger — the whole of Saudi Arabia fits into Canada roughly 5 times.
Canada sits in North America, Saudi Arabia 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 5.1×.
The old map muddied it further: Mercator inflates Canada about 4.1× and Saudi Arabia about 1.2×, so on a Mercator-style map this pair appears 17.5× apart instead of the true 5.1×.
Saudi Arabia fits 5× into Canada.
