Xinjiang: Part of this region's boundary is disputed with India. Size Versus draws Natural Earth's de facto outline, the boundary as it is held on the ground, and takes no position on it.

What fits

Xinjiang is 85% of the size of Saudi Arabia.
Saudi Arabia is larger by 292,000 km² (113,000 mi²), which is 18% of the area of Xinjiang.
Measured in Belgiums: Saudi Arabia is about 62.7, Xinjiang about 53.2.

How they differ

Saudi Arabia also has the larger population: 33.0 million against 25.9 million, 1.28× as many people.
Per square kilometre that is 17 in Saudi Arabia against 16 in Xinjiang: Saudi Arabia is 1.08× as densely populated.
Their centres are about 4,170 km apart.
On a standard web map Xinjiang looks larger than Saudi Arabia: Saudi Arabia at 24°N is drawn about 1.2× too large and Xinjiang at 41°N about 1.8×, so the map shows Xinjiang as 1.24× the size of Saudi Arabia, when Saudi Arabia is 1.18× the size of Xinjiang.
Together Saudi Arabia and Xinjiang cover 3,552,000 km², close to the size of India (3,151,000 km², 11% smaller).
The gap between them, 292,000 km², is about the size of Philippines (293,000 km²).
At Xinjiang's density, Saudi Arabia would have 30.5 million people (it has 33.0 million). At Saudi Arabia's density, Xinjiang would have 28.0 million (it has 25.9 million).
Xinjiang's centre is 17.0° of latitude, about 1,890 km, farther north than Saudi Arabia's.
Saudi Arabia ranks 15th of 246 countries and territories by area.
Xinjiang is the largest of the 31 provinces and regions of China and covers 17% of its area; it is the 29th most densely populated of them.
Xinjiang lies about 17° of latitude (roughly 1,890 km) north of Saudi Arabia.
Shared out evenly, each person in Saudi Arabia would have about 58,230 m² and each person in Xinjiang about 63,060 m².

Sources and method

Outlines: Natural Earth, 1:10m Admin 1 - States, Provinces, public domain for the region; Natural Earth, 1:10m Admin 0 - Countries, public domain
Boundary: De facto, as drawn by Natural Earth. A region is drawn whole, every island included; a country is its main territory.
Area: Measured on the WGS84 ellipsoid from the full-detail outlines, shown rounded.
Drawing: Each outline is projected with an equal-area projection centred on its own centroid, so areas stay true and the two can be laid over each other.
