This is my best effort yet, guys.
1.) I took the overall length
(18.80m) and wingspan
(13.56m) data of F-22 from Lockeed Martin's website, and use the wingspan data
(13.47m) of J-20, posted Deino earlier.
2.) I two high resolution, and most flat pictures of J-20 and F-22, I can find, and overlaid F-22 ontop of J-20, while keeping the proportion, the same.
3.) I resize the F-22 picture, until, it's wingspan is about the
same as J-20, then I align them at the nozzles. (You can also align them at the noses)
4.) Then, I took a ruler image from the web, and overlaid it ontop of F-22, and resize it and align it, so the
mark 18.8 is exactly the same as F-22's overall length.
5.) I copied the same ruler, and place it at various measurement points, and obtained the following values, by using F-22's overall length of 18.8m as reference.
(1.) F-22 overall length:
18.80m
(2.) F-22 nose-nozzle length:
16.7m
(3.) J-20 overall length:
21.64m
(4.) J-20 nose-nozzle length:
21.14m
(5.) F-22 Wingspan:
13.56m (given by Lockeed Martin)
J-22 wingspan:
13.47m (posted by Deino)
(6.) Nose to Nozzle Fuselage Length difference b/n J-20 and F-22:
4.4m
(7.) I obtained the overall length difference b/n J-20 and F-22, by subtracting 21.64m - 18.8m =
2.84m
Those values are very close to what I have posted before. I challenge anybody, who disagree with my findings to do his own researches, not just quoting values, from some very blurry satellite pictures.
So my final conclusion is
J-20's overall length is 21.6m (which is 2.84m longer than F-22), not 20.35m, and
J-20 is 4.4m longer than F-22, when measured from Nose to Nozzle.
