After so many years of them being on the small screen, it's impossible not to get to know them as real-life actors and actresses, too. Whether fans are in love with Kaley Cuoco or are super-fans of Jim Parsons, how much do they really know about their personal life? It's time to get to know this cast - so here are all their ages, heights, and relationship statuses.

10 Simon Helberg

Simon Helberg was perfectly cast as Howard Wolowitz, and he'll probably never be able to shed that role. He was born in 1980, making him one of the younger ones on the list, at 40, with his birthday being December 9th.

This cast isn't known for their height, and Helberg is actually shorter than Galecki! He's only 5'4", but his personality makes up for it. He's actually also been married since 2007 to Jocelyn Towne and has two kids.

9 Kaley Cuoco

This blonde bombshell will definitely always be Penny in the hearts of all television lovers. However, this actress has a lot more talent up her sleeve. She was born on November 30th, 1985, making her 34.

She's also a surprising 5'6", which yes, makes her a bit taller than her on-screen husband, Leonard. When it comes to love, Cuoco was married to Ryan Sweeting for three years but is currently with Karl Cook, who she married in 2018.

8 Johnny Galecki

This actor is arguably the lead on the show and definitely became famous for his role as Leonard Hofstadter. He was born on April 30th, 1975, making him only two years younger than Parsons, but a whopping 10 years older than Cuoco.

It's no secret he's a shorter fellow, clocking in at 5'5", which, is nothing to fret over! He's also been off the market since 2018 when he married Alaina Meyer. He even has one kid!

7 Kevin Sussman

Sussman is an actor and a comedian, but all fans know and love him as Stuart Bloom from this show. He's actually older than the main gang and was born on December 4th in 1970. He is also not actually that tall, but reaches the taller side on this list at 5'9".

He was married to Alessandra Young from 2006-2017, so this hilarious and lovable guy is still on the market. Of course, it's hard to think of him as anything but the guy at the comic book store.

6 Mayim Bialik

Mayim Bialik is an actress that is greatly known for this show, but she's also an actual neuroscientist! This intelligent gal was born in the same year as Galecki, but her birthday is during the holidays, on December 12th.

She's actually shorter than Galecki, too, with a fairly average height for a woman at 5'4". The best fact about Bialik is that she has two gorgeous children, but she separated from her husband after a ten-year marriage in 2013.

5 John Ross Bowie

This guy made everybody laugh whenever he appeared as Barry Kripke. It shouldn't be surprising that he's both an actor and a comedian! He was born in 1971 on May 30th, making it 49 years old.

He's been married to Jamie Denbo since 2004, but he and his wife are still free of children, which, means they're living life. He's a whopping 5'9", which actually almost makes him Jim Parsons' height!

4 Kunal Nayyar

This British-Indian actor is everyone's sweet Rajesh Koothrappali. He was born in 1981 and was born on April 30th. Yes, that's the same birthday as Jonny Galecki (what are the odds?)!

He's actually one of the tallest on the show, reaching 5'7". It doesn't matter though, because he's been married since 2011 to Neha Kapur, and he's clearly got it all figured out.

3 Melissa Rauch

This fiery actress is the perfect woman to have played Bernadette, and fans are definitely in love with this stunning and talented gal. She was born in 1980, on June 23rd, which makes her pretty close in age to Helberg.

It's not surprising she's the shortest on this list, but she's actually only 4'11"! She has so much personality to make up for it, though, and she's been off the market since 2007 and is tied to Winston Beigel. She also has one daughter.

2 Wil Wheaton

Wil Wheaton is definitely famous for being on the show, but all fans know that he actually just plays himself, and he's been a famous actor for many, many years. He was born in 1972 on July 29th, in California.

He's been married since 1999! That's totally impressive, and he has two kids with his wife, Anne Wheaton. He's also one of the taller ones this show has to offer, clocking in at 5'11". He's almost giving Parsons a run for his money.

1 Jim Parsons

Jim Parsons took the world by storm with his brilliant portrayal of Sheldon Cooper. Since then, he's certainly expanded his horizons into film. This actor is actually older than his counterparts, being born on March 24th, 1973.

He's a whopping 6'1", which definitely adds to his lanky character awkwardness. Plus, his love story is totally wholesome, and he's been tied to Todd Spiewak since 2017 when they got married.
