There’s some variation in the dimensions of every plane in the picture because of distortion effects. It’s generally best practice to choose planes that exhibit the least amount of distortion.

It would seem like camera is closer to being nearer the top of first J-20 than it is to the top of leading MKK. This means J-20 is even short than we would have estimated. It is most definitely a pure air superiority fighter. How people can still think it's an interceptor etc is beyond me. It doesn't even look like it's designed for altitude and speed. Top view is definitely J-20's best angle. Can't get tired looking at it.

I thank you, too, just ... what specifically did he get wrong Yesterday at 9:51 PM
? for example "J-20 length, as it's actually shorter"

The tail boom should be the longest point in the J-20. But that is not the case in the pic. Meaning he has chosen a J-20 further away from the camera. In my comparison I used only the planes closest to the center.

I disagree. It is a better practice to choose planes with the SAME amount of distortion. In this case, choosing the left-most J-20 for comparison is correct.
Not with perspective distortion.

In the context of the picture we are talking about, the distortion is symmetric around the centre of the picture. So, the left-most J-20 has the same distortion as the J-16's.
Say to troll get a lifeI remember you had to go through a lot personal attacks at Key-Forum. I re-checked your original estimate of 20.35 m (). Considering the J-20 in that sat pic is the demonstrator 2001/2002 (which shorter than the production version), I did some adjustments based on this new J-20 + J-16 pic and you were off only by 20 cm at most 30 cm.That is very impressive and hats-off to you.

First of all, the picture of the J-20 has been cropped, with the aircraft being originally at the center of the picture.
i.e. the J-20 is at the center of the field of view of the picture and the J-16 at the edge of the field of view.
This means that the J-20 will appear slightly bigger than the J-16 due the camera being closer to the J-20 and farther from the J-16. The J-16 is also at an angle to the field of view (which explains why the vertical stabilizers appear to be longer than the tail boom) which further makes the J-16 smaller than it would otherwise appear to be.
And then there is the question of the different amount of lens distortion between the center and the edge of the lens.
