It's pretty hard to gauge how tall music artists are when they're constantly bouncing around on stage or walking red carpets in sky-high heels. They also have tons of tricks up their sleeves to create optical illusions with their height. To celebrate the release of the documentary "Gaga: Five Foot Two" on Netflix on Sept. 22, Wonderwall.com is revealing your favorite pop stars' real heights… starting with Lady Gaga who is, as the title of her documentary reveals, a petite 5 foot 2.

Demi Lovato measures 5 foot 3. With an album dubbed "Confident," we bet she'd be happy at any height.
Though Kelly Clarkson comes in at just 5 foot 3, her amazing voice gives her a larger-than-life stage presence.
Britney Spears is just 5 foot 4, but you wouldn't know it when she shows off her gams in short minidresses.
Pink's smaller frame is probably helpful when she's on stage doing all of her aerial and acrobatic stunts. The "What About Us" singer is 5 foot 4.
Jennifer Lopez easily distracts us from her 5-foot-5 frame with her super-sexy legs. We bet her 6-foot-3 retired baseball player boyfriend, Alex Rodriguez, agrees.
Bruno Mars hits the height charts at 5 foot 5, but it can be hard to tell since he often wears heeled boots for a lift.
Also 5 foot 5? Pop icon Madonna.
Selena Gomez too! She comes in at 5 foot 5, which definitely seems to be a popular pop star height.
Though Sia's face is often a mystery, her height isn't. The "Chandelier" singer is 5 foot 5.
"All About that Bass" singer Meghan Trainor comes in at 5 foot 5 too.
Rounding out the 5-foot-5 club is Miley Cyrus, who we always thought was taller. Those pop stars and their optical illusions!
There's no doubt that Gwen Stefani is 5 foot 6, but we totally thought she was even taller. It must be the fact that she has legs for days. (Her country singer boyfriend Blake Shelton, by the way, is 6 foot 5!)
Nick Jonas hits the height charts at 5 foot 7. What he lacks in height, he makes up for in hotness.
Do these Grammys make Beyonce look taller? Queen Bey comes in at 5 foot 7.
Ed Sheeran often sits down to play his guitar during performances of his hit songs. Maybe it's to detract from his diminutive 5-foot-8 frame? No matter — we'd love the cutie at any height.
Did you know that Katy Perry is 5 foot 8? As in, she's taller than both Beyonce and Rihanna. Shocking!
Mariah Carey is also 5 foot 8! That must make it a bit difficult for her dancers to balance her when they carry her around in the air on stage.
Justin Bieber comes in at 5 foot 9. But hey, that's a whole two inches taller than his mentor, fellow artist Usher.
It's not just Adele's voice that towers. She's also 5 foot 9!
Like Adele, "Praying" singer Kesha is also 5 foot 9.
Former One Direction member Zayn Malik doesn't have to worry about how he stacks up next to his bandmates anymore. He's a cool 5 foot 9 on his own. (That's one inch shorter than his girlfriend, model Gigi Hadid.)
Taylor Swift takes the female pop star lead at 5 foot 10! But we always realized how tall the "Look What You Made Me Do" singer was thanks to those long legs of hers.
Taylor Swift's ex-boyfriend, Harry Styles, is an inch taller than her at 5 foot 11.
Also 5 foot 11? "Attention" singer Charlie Puth.
Maroon 5 singer Adam Levine hits the 6-foot mark. He's just one inch taller than his model wife, Behati Prinsloo.
Justin Timberlake beats out Adam Levine for tallest male of the bunch at 6 foot 1. Though we think he'd bring sexy back at any height.
