The Chongqing monorail trains actually fall within the same size range as typical subway cars. The following graphic shows the dimensions of the Hitachi Large Type monorail trains that the Chongqing trains are based on. Each car is 2.98m wide and has a length of 14.8m (End Car) or 13.9m (Middle Car).



This is much bigger than the cars of the former IRT lines of the New York Subway, which are 2.68m wide x 10.97m long.



Other subways do have larger train cars. The following graphic shows Toronto's, which are 3.134m wide x 22.787m long.

The point is not the size of the train but the capacity (frequency, train length, ratio of standing and sitting room, and passenger density).
Toronto's is the largest in size but has the lowest capacity (~1000 passengers per 6 car T1 series train).
New York is the smallest but has the largest capacity (~1800 passengers per 10 car R142 series train).
Chongqing is right in the middle (~1400 passengers per 6 car set).

Good and reliable comparison is impossible if you don't use the same density inside the vehicles
A 13,90 x 2,98 car or 15,65 x 2,68 car can't contain more similar people than a 22,78 x 3,13 car
(the Toronto car has not a lot of seats)

Yes it can if you don't use the space inside the car efficiently. The Chongqing monorail has walkthough cars that increases capacity. The T1's has wasted space between the cars, sliding door pockets and all the unused cabs.

Capacities are based on the context of the train's operating environment. Due to cultural differences the US uses a crush load in 6 pax/m^2 while in China and Japan its 9-8 pax/m^2. That's the best comparison, using what the train actually achieves by factoring in some local context.

Another thing, out of all the models listed the T1's are the only ones without longitudinal seating, so from a capacity perspective it has the most inefficient seating arrangement and the most seats per area.

Do not forget that Americans are mostly stout and obese while Asians (Chinese, Korean, Japanese etc) are slim.

Again only 6-car B-size trains. Why don't they take into account the mistakes of the past made in other cities?

I wrote "similar people" precisely thinking about this fact

Yeah, Americans don't like to crowd together as much, having been on at peak times in both Boston and Beijing, in Boston, the train left after it was reasonably crowded, but still enough room to move arms around, leaving many on the platform behind, Beijing was holy****ingshit levels of crowdedness and you were SQUEEEEEZED in there, and everyone on the platform tries to jam into the train as tightly as possible.

That is called maximum efficiency, minimum comfort. People are just get used to it.

Line 3 will use 8 car trains next year, capacity enhanced by 1/3
Line 2 thinking about going 8 car in the near future.

Loop Line (Cleverly named Line 0) started construction in the end October. FYI will use 6 car A size trains, music to _Night City Dream_'s ears.

B cars are fine. Just stop running them in 6 car sets every time. Tokyo and Osaka Subways use very similar if not exactly the same size cars yet they run them mostly in the 10 to 8 car formations.
