I think it is very difficult to define size to a galaxy, as there is not real cut off point. Recent observations showed a "halo" of Stars around the Galaxy - a bit like suburbs to a city. Putting the size to 500,000 light years across. Current thoughts are that it is twice the size of our own Galaxy, so around 200,000 light years across.
Maybe someone else can contribute a more recent guesstimate.
What else can I help you with?
Put theses in increasing size. Andromeda galaxy Earth Sun Universe?
Earth, Sun, Andromeda galaxy and then the universe. increasing size------------------------->
