In 2016, Wevers upgraded the difficulty score of her beam routine by seven-tenths and won gold at the Olympic Test Event.
She then became the Dutch national champion on beam with a score of 15.650.

In July, Wevers was named to the Dutch team for the 2016 Summer Olympics, and her sister Lieke also made the team.
In qualifications on 7 August, Wevers scored 14.408 on uneven bars and 15.066 on balance beam, advancing to the final in fourth place.
On 15 August, she won the gold medal in the balance beam final with a score of 15.466, outscoring Americans Laurie Hernandez and Simone Biles, who won silver and bronze.
This was the first time a Dutch woman won an individual medal in artistic gymnastics, the second time a Dutch woman won a medal in artistic gymnastics after the Dutch team won gold at their home Olympics in 1928, and the second time a Dutch gymnast won an individual medal, following Epke Zonderland's win on the horizontal bar at the 2012 Summer Olympics.
Wevers was selected to be the country's flag bearer at the closing ceremonies.

"Dutchwoman Sanne Wevers won gold with [a] routine that stood out with a sharp contrast in styles to the others ... [She] performed a routine that was short on acrobatic skills, but big on pirouettes, a skill that Wevers is known for.
She pulled off a triple turn without a hint of hesitation early in the routine and later added a turn that reversed fields and headed back in the other direction."
