Cole and his brother, Dylan, began acting at the age of eight months following a suggestion from their grandmother, Jonine Booth Wright, who was a drama teacher and actress.
Much of Sprouse's early career was shared with his brother—some of their earliest roles were shared roles as one baby or child in commercials, television shows, and films.
Due to child labor laws in California restricting the amount of time children can be filmed in a day, casting twins in a single role allows more time for one character to be filmed.
Some notable roles he shared with his brother include the characters of Patrick Kelly in the sitcom Grace Under Fire from 1993 to 1998, Julian in the 1999 film, Big Daddy, and young Pistachio Disguisey in 2002's The Master of Disguise.
In 2001, Cole began appearing in episodes of NBC's television sitcom Friends, as Ross Geller's son, Ben; this role was his first role in which he did not appear with his brother.
As he and his brother grew older, they began taking on more roles as separate characters but often still worked on the same projects.
Their first role as separate characters in the same production was as kids in a MADtv sketch.
Sprouse portrayed Cody Martin in the 2005 Disney Channel original series, The Suite Life of Zack and Cody alongside his brother; he reprised the role in the show's 2008 spinoff, The Suite Life on Deck and its related film.

On February 9, 2016, Sprouse was cast as Jughead Jones in The CW's teen drama series Riverdale, based on the characters of Archie Comics.
The series premiered on January 26, 2017.

In 2019, Sprouse starred in Five Feet Apart, a romantic drama which was released in March and performed well at the box office.
He plays a cystic fibrosis patient who falls in love with a girl (played by Haley Lu Richardson) with the same disease.
It was his second lead role in a major theatrical film, 20 years after his first, Big Daddy.

Sprouse produced and starred in the eight-episode podcast Borrasca in 2020.
