It has a diameter of just over 50,000 km. That makes it the third biggest planet in our solar system, but quite a bit smaller than Saturn, the second biggest planet, comparitively.
I also like Uranus. Despite it looking similar to Neptune at first, it has a lot of differences. Its perceived surface appears a lot smoother with less storms than its ice giant counterpart. It also has a significant ring system second only to Saturn's. Uranus feels like the gemstone of the Solar System to me. I just wish its moon system was more interesting, but I like how they follow its nearly 90 degree tilt with their orbits.
