Ok thanks. So size dont really matter? (I look like the biggest country in the world on the map)
Size does matter, but a lot of your size is in Siberia. You're basically Russia + Scandinavia, so most of your provinces are very large in size. You've risen quite high in total development too though, which is basically the total value of your provinces (divided into tax, production and manpower). Eboue is smaller on the map, but his provinces are both physically smaller and much higher average value.
