Stephanie is known for her perky personality. She was a blabbermouth in the earlier seasons, but got over that eventually, though her younger sister Michelle received that trait as well (but she grew out of it, also, at an earlier age than Stephanie). She has blonde hair and green eyes. Stephanie is often defiant of her sister D.J. in the earlier seasons, but they eventually become much closer and bicker less as the series progresses, though her nosy habit of reading D.J.'s diary never faded, though her snooping on D.J.'s phone calls was gone by then. Stephanie is the most excitable of the girls—a trait she inherited from her mother, and the most talkative—a trait from her father. She often struggles with being the middle child and wanting attention (as seen in season two's "Middle Age Crazy"). Still, she is quite well-behaved and very hard on herself whenever she did something wrong. Although often noble and trustworthy, Stephanie has her weaknesses, which include being able to be swayed by her peers into dangerous situations, and prying. Like D.J., Stephanie is a good student. Her favorite color is pink. Stephanie is very athletic, as she also loves to dance and she performs ballet very well. Like D.J. and eventually Michelle, Stephanie is a member of the "Honey Bees" (an organization similar to Girl Scouts) in the first few seasons. Stephanie shares a room with D.J. until season five, when D.J. moves into Michelle's room and Michelle moves in with Stephanie.
She has a teddy bear named Mr. Bear, which she is very attached to, as Pam gave him to her when she and Danny brought Michelle home from the hospital. Mr. Bear wears a detective coat and a dark hat, and has a scar under one of his eyes. After season seven, Mr. Bear no longer makes an appearance, but he is mentioned in the season seven episode "The Apartment"; however, seeing as Danny wanted the stuffed animals raked up as well as Michelle's "Hobby Day" leaves, it seems that she did not completely get rid of him. As she mentions several times throughout the series, but is only heard twice (season two's "Goodbye Mr. Bear" and season five's "Oh Where, Oh Where Has My Little Girl Gone?"), "Mr. Bear is not a toy. He's a member of the family."
Though out the series, Stephanie has gone through many tough issues (possibly more than the other Tanner girls), such as smoking (in "Fast Friends"), "make-out parties" ("Making Out is Hard to Do"), joy riding ("Stephanie's Wild Ride"), witnessing child abuse (of a friend in "Silence is Not Golden"), as well as the death of her mother when she was only five years old (and, as an adult, not being able to have children).
She goes to a different school from D.J. when she hits junior high, because of zoning problems related to the change from junior highs (grades 7 & 8 or 7–9) to middle schools (where 6th graders are no longer elementary school). This change was common in the early 1990s across the United States, which is when it takes place.
Stephanie enjoys her father-daughter time when she is little. She has a stage where she only wants to be with Danny, and never wants him to leave when she is young. Danny is a typical over-protective dad when she starts dating. However, in the season four episode Happy New Year, when Stephanie kissed Rusty, Danny did not seem to mind one bit (even though he only showed surprise and amusement on his part).
Uncle Jesse is a major role model of hers when she is little. Jesse thinks that she is very cute, and has also taught her how to ride a two-wheeler. Stephanie gets Jesse to do a lot of things for her, as displayed below:
Stephanie: "Uncle Jesse, let's play ballerina."
Jesse: "Uncle Jesse doesn't want to play ballerina."
Stephanie: "Yes he does."
Jesse: "No he doesn't."
Stephanie: "Yes he does."
Jesse: "No he doesn't!"
Stephanie: [pretending to cry] "Yes he does."
Jesse: [reluctantly] "How do you play ballerina?
Stephanie later forms a band with Kimmy and Gia, making Jesse proud, but also making family differences emerge when Jesse proves to be an overbearing band manager.
Stephanie, perhaps, has the best adult-to-kid relationship with "Uncle" Joey. Joey helps her out quite frequently when she is younger. However, as Stephanie grows older they do not interact as much.
D.J. is Stephanie's older sister. When Stephanie is younger, D.J. is her role model. Before, she believed D.J. was born so she would have someone to play with. She is very curious about her social life and listens in on her phone calls, reads her diaries and even attempts to find them, which (as described by D.J. in the season 3 episode Bye, Bye Birdie), contains her "hot stories"; and even once, she even said that she had a journal, and not even Stephanie knew that D.J.'s "journals" and diaries were one and the same). Stephanie and Michelle sometimes get into D.J.'s business together; they were shown once reading her diaries ("Be True to Your Preschool"). She also borrows D.J.'s clothes many times while D.J. is taking showers and other times when she is not in the room, though Michelle joined in on this only once ("Support Your Local Parents"). They get along better in the later seasons. In the first four seasons and part of the fifth, they share the same room, where D.J. has a mandatory rule where Stephanie must keep her own stuff on her own side of the room (similar to the rule she set in the series premiere, where Stephanie could not set foot on her side of the room, in addition to being prohibited from touching her stuff). After her awful time at the mother/daughter Honeybee sleepover ("Slumber Party")—where the other girls that do have mothers were happy and she was not, and even wondering why she couldn't be happy like them—Stephanie tearfully explains that when D.J. was 8 years old, she got to attend one with their mother Pam; D.J. then explains that that does not mean that she doesn't miss her as much as Stephanie does. She also explains that when she attended the sleepover with Pam, she felt the same way Stephanie does when she looked at those girls who didn't have a mother at that time, and when Stephanie asks how she can make the feeling go away, she explains that Stephanie is special in the same way she is, in that they have something that the other girls don't have; namely Danny, Joey, and Jesse. After their talk, D.J. decides to accompany her on the return trip to the sleepover. In "A Pox in Our House", when Stephanie gets the chicken pox, D.J., who was invited to her first non-mother/daughter Honeybee sleepover since Pam's death, forgoes it to take care of her and the rest of the family. In "Sea Cruise", it is announced that D.J. is retiring as "Queen Bee" and from the Honeybees as a whole, so in true fashion, she passes the crown—or rather, antenna—onto Stephanie.
Michelle to Stephanie is much like Stephanie to D.J. Michelle looks up to Stephanie, and Stephanie, even though she loves her, is annoyed by her. Michelle is not as nosy as Stephanie was, however, as Stephanie is the one who encourages her to be nosy. Michelle usually accompanies Stephanie when they sneak into D.J.'s room to read her diary (which is one thing they enjoy doing without getting on each other's nerves, see above). In season three's "Divorce Court", she literally moves her bed out of her and D.J.'s room into Michelle's room, despite Danny telling both of them that Michelle was too young for a roommate at the time. From season five on, Michelle becomes Stephanie's new roommate and her pencil bed takes the place of Stephanie's old bed, while Stephanie gets D.J.'s old bed (and the desk and chair next to it). At first, Michelle was against the idea of being Stephanie's roommate (because she hated being called a "kindergarten baby" and a "little shrimp" by Stephanie and hated having her age of 4 ¾ misinterpreted and misjudged as 4 whole years old by both her sisters), but she accepted after Stephanie tempted and bribed her with a bag of cookies. Stephanie also alleviated the pain by inviting Michelle into a Big Girls' Club and taught her how to sing its short, but simple, song. While she initially had a problem with Michelle's Barney the Bear wall hanging, she slowly began to accept it, as she wanted to get rid of it, while Michelle, in return, wanted to get rid of Mr. Bear; this was part of a condition that to get into the Big Girls' Club, all the baby stuff had to go. The bears stayed, but since it was never mentioned, the two girls possibly got rid of the rest of their baby stuff. Like D.J., Stephanie's ways of caring for Michelle go beyond just safety. In season eight's "My Left and Right Foot", when they both find Michelle soaking her shrink-wrapped feet in a bucket of ice water in an effort to shrink her feet, she and D.J. immediately get Michelle out of her frigid foot bath, keep a tight grip on her to stop her from getting back into the tub, and insist that if she continues, she will freeze her feet off or that bunions will grow and possibly cause permanent damage; though Stephanie was the one who said Michelle would freeze her feet off, while D.J. simply asked Michelle if she was "making a bunion Slurpee", but she did concur with Stephanie on Michelle's extreme possibility of freezing her feet off. In season five's "Captain Video (Part 1)", Stephanie retires from the Honeybees, and in true fashion, she passes the crown/antenna onto Michelle, and explains that the reason why Michelle's sash does not have badges is, like the Girl Scouts, they cannot simply get them; they have to earn them.
Stephanie is glad when Becky comes into her life, having a motherly figure to look up to. They get along well.
Nicky and Alex Katsopolis
Stephanie is very good with her twin cousins. She is not afraid to babysit—even in one episode when Nicky and Alex panic when she gives them the wrong pajamas. Once, when Kimmy was babysitting, she took over for Kimmy—for a price. Afterwards, since Stephanie was the one who did all the work, she was the one that earned all the money.
Kimmy is annoying to most everyone including Stephanie. They would often make fun of each other (as they sounded like a great comedy team). Stephanie is more tolerable of her in the last couple of seasons, though they both constantly shoot insults at one another. It's thought to be normal of them; Kimmy once asked sadly if Stephanie was mad at her when she had not insulted her back.
Gia would become Stephanie's best friend when she grew older. In the beginning, Gia would often get Stephanie into trouble and has bad judgement (although she does grow out of it when they become friends). She is like Stephanie's Kimmy, since she brings excitement into her life.
Rusty is Cindy's trouble-making son. To get his mother out of his relationships, he pranked her boyfriend and his family. When the Tanners were the victims of his pranking, Stephanie, Michelle, and D.J. finally got him back. Once, Rusty teased Stephanie that he was going to kiss her on New Year's Eve, to drive her crazy. And it did. When he told her that he wouldn't actually kiss her, she surprised him and kissed him. After that, it was rumored that he liked her.
Stephanie likes Steve, but along with Danny, makes fun of how much he eats at their house.
Stephanie loves Comet. She was very enthusiastic about getting a dog, and grows up loving him. When they first got Comet, she had suggested they name him "Mr. Dog" after Mr. Bear.

After Full House, Stephanie moved to London, England to become a DJ (comically, under the name of "DJ Tanner"). She later returned home to San Francisco.
- Main article: Fuller House
In Fuller House, Stephanie steps into a role similar to that which her Uncle Jesse played in Full House. She moves in with her recently widowed sibling in order to help raise the three children that D.J. is now left to raise as a single parent after her husband dies. Also like Jesse, music is also a big part of Stephanie's life.
After D.J. reluctantly agrees to let Max have a dog the Tanner-Fuller family brings Cosmo home in "The Not-So-Great Escape". Cosmo is the son of Comet Jr. Jr. and the grandson of the late Comet.
Stephanie reveals to D.J., in "Mad Max", that she is unable to have children. Stephanie found out that she was infertile while she was living in England. She did not say anything to D.J. about it because Tommy Fuller, Sr. had just died. In addition to being a DJ, she becomes the coach for the Van Atta Middle School dance team and occasionally sings.
Stephanie goes to London in the summer before coming back to San Francisco. In "Welcome Back", she kisses Jimmy Gibbler, Kimmy's younger brother. She begins dating him in season two.
She writes a song for her boyfriend which flops the First time it is released but soon becomes an Internet hit with a better video. It garners 400,000 views.
Stephanie is supposed to appear on an episode of Wake Up USA, but because of being stuck in a cell set along with Jesse, Becky and Fernando, runs out of time.
- Full House Stephanie: These 33 books were written from the point of view of the Tanners' middle daughter, Stephanie Tanner. They take place with Stephanie in a different middle school, likely because of a slightly different redistricting plan compared to the one mentioned in season seven's Fast Friends. She has different best friends, Allie Taylor and Darcy Powell, as well. Though these are book creations, she has known Allie since kindergarten, and there are several places in the first five seasons of Full House where fans think an unnamed extra could be Allie. The first ten of these books overlap with seasons seven and eight of the TV series, though the school is not the only difference; there are a number of differences in the Tanners from the series. This series begins with Stephanie being pressured to join a clique called the Flamingos, by completing a series of dares. She almost does the last one, though she's not sure if she wants to, before D.J. catches her trying to steal Danny's phone card. Stephanie explains tearfully what was happening, and D.J. helps her to understand what the Flamingos were really up to: they wanted the phone card to use to call boyfriends. Stephanie and the Flamingos become fierce rivals, though not all books surround this rivalry or even show the Flamingos.
- Full House Sisters: These 14 books focus on Stephanie's friendship with younger sister Michelle and comical situations that occur between them. The sisters often alternate points of view in the story.
- D.J./Stephanie Flip-Over Book: This book features D.J. and Stephanie's opinions on different events in the book.
