In 2004, she played the lead role in romantic comedy Win a Date with Tad Hamilton!, opposite Topher Grace. It was critically and financially unsuccessful. Also in 2004, she portrayed actress Sandra Dee in Beyond the Sea. Reviews were mixed, and it was a box-office bomb, though Bosworth's performance received critical acclaim. The next year, she portrayed Chali, a Hare Krishna, in the film adaptation of Myla Goldberg's novel Bee Season (2005), about a dysfunctional Jewish family.
Bosworth starred as Louise in the psychological drama The Girl in the Park with Sigourney Weaver, Alessandro Nivola and Keri Russell, written and directed by Pulitzer Prize winner David Auburn in his directorial debut. It premiered at the 2007 Toronto International Film Festival, and was subsequently picked up by The Weinstein Company. Alissa Simon of Variety wrote that Bosworth "tries her best, but her character's too extremely drawn." Bosworth also filmed 21, an adaptation of the book Bringing Down the House, in early 2007 in Boston, Massachusetts and Las Vegas, Nevada, reuniting with co-star Kevin Spacey and director Robert Luketic. It garnered mixed reviews, with Joanne Kaufman of the Wall Street Journal concluding, "Very little adds up in 21."
In 2006, she optioned the film rights to Catherine Hanrahan's novel Lost Girls and Love Hotels and was set to produce the project with filmmaker Nadia Connors. It was finally made with Alexandra Daddario in the lead role. In 2010, she starred in The Warrior's Way, shot in New Zealand with Korean actor Jang Dong-gun and Geoffrey Rush. It was one of 2010's biggest box-office flops, grossing only slightly more than $11,000,000 worldwide against its $42 million budget. Bosworth has said about her roles, "I just don't do comfort zones."
In January 2008, Bosworth was named the new face of Calvin Klein and appeared in their ad campaigns. She also became the spokesperson for the American luxury bag brand Coach in Asia.
Bosworth designed a jewelry line with friend and celebrity stylist Cher Coulter called JewelMint, which launched in October 2010. The first vertical market venture of MySpace co-founder Josh Berman and Diego Berdakin's social commerce company, BeachMint features designs by Coulter and Bosworth.
In 2012, Bosworth was the face of skincare brand SK-II.
She appeared in 10 films between 2011 and 2014, moving away from the big-budget Superman franchise into lower-budget film roles, such as Still Alice with Julianne Moore. The short film Lov, filmed in Slovenia, featured her and launched fashion designer Vanessa Bruno’s fall 2011 campaign.Quereshi, Afsun.

In 2013, Bosworth was cast in the horror film film Before I Wake directed by Mike Flanagan; it was released on Netflix in 2017.
In 2018, she was cast in the postapocalyptic horror film film The Domestics released on June 28 that year.
In September 2018, Bosworth was announced as having the main role of KC on the Netflix science-fiction miniseries The I-Land. It was released on September 12, 2019. That year, she was cast in the sci-fi thriller Genesis.
In 2018, Bosworth and Polish opened the Montana Institute of the Arts, a summer school for filmmaking students.
She had a relationship with actor Orlando Bloom from 2002 to 2005.
In mid-2011, she began dating American director Michael Polish, whom she met earlier that year when he directed her in Big Sur. They announced their engagement in August 2012, and married on August 31, 2013, in Philipsburg, Montana. Bosworth became the stepmother to Jasper, Polish's daughter from a previous marriage, whom Bosworth said was “hands-down the greatest unexpected gift of her life”. In August 2021, she announced her separation from Polish. They legally divorced in March 2023.
Bosworth is a Buddhist, following Mahayana Buddhism. She enjoys running and Pilates, and practices meditation. She is a fan of the Dallas Cowboys.
Because Bosworth's grandparents suffered from Alzheimer's disease, the book Still Alice has had an impact on her. She contacted the author, Lisa Genova, and later landed a co-starring role in the Still Alice of the book.
In January 2022, it was reported that Bosworth was in a relationship with actor Justin Long. In April 2023, the couple confirmed their engagement. A month later, Long indicated that the couple had married. On July 18, 2025, Bosworth and Long welcomed their first child, a daughter.
