Summary

  • The Big Bang Theory cast features a varied range of heights, with Melissa Rauch as the shortest at 4'11", enhancing her big personality.
  • Height preferences in casting were evident, with Christine Baranski and Lauren Lapkus standing out as the tallest female cast at 5'10" and 5'10" respectively.
  • Brian Posehn's portrayal of Bert Kibbler, at 6'7", adds a fascinating dynamic with his towering height and soft-spoken nature in The Big Bang Theory.

The Big Bang Theory cast creates one of the most beloved television ensembles and part of the joy of their chemistry is the unique appearance of each character, especially in their heights. Many actors are actually much shorter than they look, as the camera angles, or even clever lifts, make them look taller than they really are. Conversely, sometimes it's tough to tell how toweringly tall an actor might be when seeing them on screen from the comfort of the couch. When it comes to the heights of the cast of The Big Bang Theory, they vary quite a bit.

When The Big Bang Theory cast is all standing together, their height differences are easy to spot and sometimes become the topic of conversation. Most poke fun at Bernadette's small stature, mainly because her big personality is in stark contrast to that. Meanwhile, Sheldon is overpowering not only in his personality but his height, too. Alongside the main cast, fans also wonder how tall (and short) other cast are on the show.

Screen Rant has reached the ripe age of 20, and each year of its existence between 2003 and 2023 has contained one TV show that rose above the rest.

Melissa Rauch

Bernadette Is 4'11''

It's obvious that Melissa Rauch of The Big Bang Theory cast, who plays Howard's firecracker wife Bernadette Rostenkowski, is the shortest person on the show. They mention her tiny stature often, complemented by her high-pitched, shrill voice — which is not how Rauch actually sounds. Standing under five feet tall, Rauch measures in at just 4'11'', making her the shortest actor on the show.

Despite this, however, she has the biggest personality and often dominates over not only her husband, Howard, but the others in the group. Most of them talk about how they are afraid of her, proving that size does not matter when it comes to confidence. After The Big Bang Theory, Rauch went on to star in the Night Court reboot as Judge Abby Stone, who happens to be the daughter of the former Judge Harry Stone from the original run of the sitcom.

Carol Ann Susi

Howard's Mom Is 5'0"

Carol Ann Susi was one cast member who never appeared on The Big Bang Theory in person. That is because she was someone who was only known by her voice. Of course, Susi starred on the hit sitcom as Mrs. Wolowitz, Howard's overbearing and angry mother. If fans had seen her on the show, they would have realized that Susi was one of The Big Bang Theory's shortest actors, standing only 5'0" in height.

Sadly, The Big Bang Theory, and there was a very good reason this had to happen. It is because Carol Ann Susi also died in 2014, and the show honored the actress by writing her out with a touching death that hit Howard quite hard. While no one ever saw Susi, comparing her height to others, her voice was always bigger than almost any other character.

Sara Gilbert

Leslie Is 5'3"

Roseanne alum Sarah Gilbert played Leslie Winkle in The Big Bang Theory cast. Fans missed Leslie's dynamic with Leonard and Sheldon in later seasons. She was a lot like Leonard but didn’t know how to tolerate Sheldon quite as well. Nevertheless, Leslie wasn’t the shortest of the group, but she wasn’t the tallest either. She was most known for her quick comebacks against Sheldon and her on-and-off relationship with Leonard.

Some believe Leslie is one of the most underrated characters on The Big Bang Theory. She was one of only a few female colleagues and she was downright hilarious. After her role on The Big Bang Theory, Gilbert returned to headline the cast of The Conners, reprising her role as Darlene. In an interesting bit of trivia, Johnny Galecki also reprised his role on THe Conners as David Healey, Darlene's absentee husband.

Aarti Mann

Priya Is 5'3"

Like many other of The Big Bang Theory cast, Aarti Mann is of average height in of The Big Bang Theory cast. Her character Priya in introduced as Raj's sister and later ends up becoming Leonard's ex-girlfriend. Priya and Leonard had a solid relationship and probably would have ended up together if it hadn't been for having to do long distance. It helps that they complemented each other height-wise, as there were only two inches separating them.

However, it was for the best because fans wanted Leonard and Penny to be the endgame more than Leonard and Priya, and some fans did not like how Priya treated Leonard at times. As Raj's sister, she and Leonard staying together could have become awkward for their friendship. Mann later played Meera in The Donor Party and Violet Ebner in The Recruit.

Simon Helberg

Howard Is 5'4''

Simon Helberg is technically the shortest male cast member on The Big Bang Theory. Helberg, of course, plays Howard Wolowitz, an engineer with an inflated sense of confidence and a weirdly close relationship with his mother. Howard is often made fun of by his friends for not having a doctoral degree. His shorter stature also plays well with him always trying to show his self-confidence, yet always lacking in self-worth.

He doesn't appear to be as short, since the other guys are not much taller than he is, with the exception of Sheldon. With his wife Bernadette several inches shorter, it also makes Helberg appear taller than he is since many of his scenes include her by his side. Helberg recently played Dimitri in Space Oddity and had a brief stint on Poker Face as Luca.

In early seasons of The Big Bang Theory, Howard Wolowitz was creepy enough to be unlikable. Fortunately, a vital new character's arrival fixed this.

Mayim Bialik

Amy Is 5'4''

Interestingly, Mayim Bialik of The Big Bang Theory cast is the same height as Helberg at just 5'4'', which makes her one of the shortest women on the show. She is also nine inches shorter than her on-screen boyfriend, Sheldon. Bialik plays Amy, Sheldon's love interest and eventually his wife. There are many ways Amy matured throughout The Big Bang Theory, but most importantly, she was pivotal in helping Sheldon grow and evolve.

Bialik was known before this role for the '90s sitcom Blossom. She is also known for being the only cast member from The Big Bang Theory to understand the scientific lingo the core group uses since she has a Ph.D. in neuroscience. Bialik has voiced Amy on Young Sheldon, headlined the series Call Me Kat, and even temporarily took on the role of one of the hosts of Jeopardy! after host Alex Trebek died.

Johnny Galecki

Leonard Is 5'5''

It is pretty well-known that Leonard Hofstadter actor Johnny Galecki isn't exactly one of the tallest actors in the Big Bang Theory cast, as he is only 5'5", which is a full inch shorter than Kaley Cuoco, who plays his love interest and eventual wife, Penny. In fact, the two actors also dated in real life at one point.

Galecki has been acting for decades. While he is best known for playing Leonard on The Big Bang Theory, other notable roles include playing Darlene's boyfriend in Roseanne—and her ex-husband in the sequel series The Conners — as well as Griswold son Rusty from National Lampoon's Christmas Vacation and Max Neurick in the film I Know What You Did Last Summer. Since leaving The Big Bang Theory, Galecki has stepped out of the spotlight and only takes on choice roles in his acting career.

Kaley Cuoco

Penny Is 5'6''

As one of the tallest of the shortest The Big Bang Theory cast on the show, Kaley Cuoco, who plays Penny, is an average 5'6'', which is fairly tall considering the height of some of the other actors on the show. As one of the show's original cast , it's her presence in the building when she moves in that sets the stage for the entire premise. It also helps to have at least two male cast shorter than her, as it makes her look a little more intimidating.

Cuoco rose to fame with her role on the sitcom 8 Simple Rules and fantasy series Charmed, but it was her Big Bang Theory character Penny on this show that put her on the Hollywood map. She went on to win awards for her role on The Flight Attendant, a show she also created and executive produced. She also voiced Harley Quinn in the Max series and starred in the comedy thriller Based on a True Story on Peacock.

Laurie Metcalf

Mary Cooper Is 5'7"

In The Big Bang Theory cast, Laurie Metcalf plays Sheldon Cooper's mother, Mary Cooper. Mary is a devout Baptist who is out of touch and dated, but she adds comic relief whenever she comes to visit her "Shelly." Although her son is very tall, Mary is of slightly above average height at 5'7".

She ranks among the best relatives on The Big Bang Theory. Metcalf rose to fame as Aunt Becky on Roseanne, a role she has reprised for the sequel series The Conners. She also received an Oscar nomination for her performance in Lady Bird. She does not play Sheldon's mother on Young Sheldon, but there is still a connection. Audiences who notice that Zoe Perry, who plays a young Mary on Young Sheldon, bears a striking resemblance to Metcalf are correct: Perry is Metcalf's real-life daughter.

Kunal Nayyar

Raj Is 5'7''

Kunal Nayyar is in the middle when it comes to the height of The Big Bang Theory cast, standing at 5'7''. Many of the women Raj Koothrappali dated on the show stood taller than him, though he is slightly taller than his best friend, Howard. Keeping him shorter than his love interests helped show Raj's insecurities on the show, but keeping him taller than Howard did the same for his friend.

Nayyar played Raj, one of the most changed core characters on the show, who initially had selective mutism that made it impossible for him to speak to women. While he could be problematic in his treatment of women after he conquered his condition, Nayyar's acting helped keep him at least likable during these storylines. He most recently appeared in the Apple TV+ thriller Suspicion and headlined The Storied Life of A.J. Fikry.
