GDP rankings are as follows from the last posted results (2018):

  1) United States 20,544,343.46
  2) China 13,608,151.86
  3) Japan 4,971,323.08
  4) Germany 3,947,620.16
  5) United Kingdom 2,855,296.73
  6) France 2,777,535.24
  7) India 2,718,732.23
  8) Italy 2,083,864.26
  9) Brazil 1,868,626.09
  10) Canada 1,713,341.70

So out of "EU" it's only Germany which was larger according to those figures (from the World Bank).

Of course things will have changed over the last couple of years, but I doubt it is substantially different in terms of order.
