White was born with a Tetralogy of Fallot, a congenital heart defect for which he endured two open-heart operations before the age of one. He stands 5'8" (1.73 m) tall. He spent his formative years riding Okemo Mountain and Bear Mountain, small ski resorts found in Ludlow, Vermont, and the San Bernardino Mountains of Southern California.

Addressing his perception of the nickname "The Flying Tomato", Rolling Stone wrote, "he used to embrace it, even wearing headbands with a flying-tomato logo, but he has grown tired of it." He has also been nicknamed as "animal", a reference to a character from the satirical puppet show The Muppet Show.

In February 2009, Red Bull built White a halfpipe completely out of natural snow in the back country of Colorado on the backside of Silverton Mountain, coordinates (37.838801,-107.710299).

White's skateboard career took place during the same time he was rising through the snowboard ranks. White quickly drew the eyes of many in the skateboarder scene including professional skateboarder Tony Hawk. At this point Hawk befriended the nine-year-old White at a local skatepark and mentored him, helping him turn pro in skateboarding at the age of 17. White has gone on to win many titles on his skateboard, most notably winning the overall title of Action Sports Tour Champion, as well as being the first person to compete in and win both the Summer and Winter X Games in two different sports. Following in his older brother's footsteps, White switched from skiing to snowboarding at age six, and by age seven he received his first sponsorship. White has participated in two Winter Olympics in his career. At both the 2006 and 2010 Winter Olympics, White won gold in the snowboard halfpipe event. White has also participated in the Winter X Games, where he has won a medal every year since 2002. Including all winter X Games competitions through 2009, his medal count stands at 15 (10 gold, 3 silver, 2 bronze), including the first four-peat winner by a male athlete in one discipline, the snowboard slopestyle. White's streak was snapped in 2007 when he lost to Andreas Wiig and Teddy Flandreau, with White taking the bronze. He won the Air & Style Contest in 2003 and 2004.

At the 2006 Winter Olympics, White won gold in the halfpipe. After his first run in qualifications, White was almost out of competition, scoring only 37.7. On his second run, he recorded a score of 45.3. In the finals, White recorded a score of 46.8 (50 is the highest possible score) to win. Fellow American Danny Kass won the silver with a points total of 44.0.

Executing a near-flawless second run, White captured his third consecutive snowboard halfpipe title at the 2008 U.S. Open Snowboarding Championships to go along with his third US Open slopestyle competition. This followed White's win at the 25th (2007) Burton US Open, where he placed third in slopestlyle and first in the halfpipe. At the 2007 Open, White was also crowned the first "Burton Global Open Champion". His take for the event was $100,000 (Global Open Champ), $20,000 (1st Place Halfpipe), $90,000 (3rd Place Slopestyle), and a new Corvette

On November 16, 2008 White Released his first videogame "Shaun White Snowboarding" in North America.(November 14, 2008 in Europe) Shaun White:Snowboarding was the 20th best-selling game of December 2008 in the United States.[citation needed]

There was a lot of controversy over who won the 2009 SuperPipe at Winter X Games XIII[citation needed]. Kevin Pearce had 5 hits in the pipe, and all were the same tricks White did in his final run. White, on the other hand, had 6 hits and he started off his run with a big backside rodeo 540 where Pearce started his run off with a big grab. Although Pearce went bigger, he only had 5 hits, and his first hit wasn't as technical as White's first hit.[citation needed] Judges came to the conclusion that White deserved the better score because he started off with a more technical trick and he had 1 more hit than Pearce.[citation needed] With the win, White became the second competitor, after Tanner Hall, to win a gold medal in the superpipe in consecutive years at the Winter X Games. He also won a gold medal in Slopestyle, finally winning gold after 2 straight years of bronze.

On February 14, 2009, White won the FIS World Cup Men's Halfpipe event at Vancouver's Cypress Mountain. Out of the gate in his first qualifying run, he qualified immediately with the day's best score of 45.5. With a thumb sprained on an over-rotated backside 1080 in the second qualifying run, he clinched the event with the first of his two runs in the finals. His first finals run was awarded the highest score ever in FIS halfpipe, a 47.3.

At the 2010 Winter Olympics in Vancouver, White again won gold in the halfpipe. In the finals, White recorded a score of 46.8 on his first run, which proved a high enough score to secure the gold medal without a second run. He performed his second run anyway, as a victory lap, ending his run with a well-anticipated Double McTwist 1260 which he named The Tomahawk. This second run resulted in a record score of 48.4 (50 is the highest possible score) enlarging his margin of victory. His nearest competitor won the silver with a points total of 45.0, 3.4 behind White.
