What is your favorite world size?

I'm not necessarily a new world builder, but the world I'm making right now is the only one I've spent a huge amount of time on. It's 2048 x 2048 and I've actually found it really enjoyable, as everything is spread out just how I wanted it to be. I'd say I'm more likely to build large worlds in the future because of this, but I guess time will tell about that for sure. :)
