Sheldon Cooper has an IQ of 187. This is so high that IQ tests are not even built to handle it. He has 2 doctorates and works as a theoretical physicist and has an eidetic memory (can recall the exact scene with the mind's eye). Sheldon is a 6 sigma IQ, likely to be 1 in 500 million people.
Bones is a forensic anthropologist with 3 doctorates and exceptional skill in her areas. Like Sheldon, she also lacks in other {social domains". Her IQ could be in the 160s.
Howard is just a masters in engineering, but speaks 7 languages, juggles, sings, plays piano, does magic, goes to space, builds robots, has creepy social skills, exceptional humor, and generally fun. He is very likely the most all-round genius of the whole cast.
Arguably, Sherlock Holmes might be the smartest TV show character in history given the complexity of successful work without much "plot armor". His IQ is likely to be 190-200,, with exceptional deduction, reasoning, knowledge, and learning capacity. Probably a 1 in 4 billion kinda guy.
