Individual all-aroundThe final was held on October 13. None of the medalists from the previous year were able to compete to defend their title as the gold and bronze medalists—Aliya Mustafina and Rebecca Bross, respectively—were both unable to compete at worlds due to knee injuries, and silver medalist Jiang Yuyuan did not qualify high enough over her teammates. A number of gymnasts ranked high enough to make the all-around final, but did not qualify due to the two-per-country rule. All the gymnasts from the US that competed in the preliminary round ranked in the top 24. The gymnasts affected were Gabby Douglas, Sabrina Vega, and McKayla Maroney of the United States. Also affected were Tan Sixin and Jiang Yuyuan of China, Yuko Shintake and Yu Minobe of Japan, and Anna Dementyeva of Russia. The last gymnast to qualify was Carlotta Ferlito, who ranked 32nd in the preliminary competition.

As her first world championships was in Indianapolis in 1991, she has been competing at an international level since before her fellow vault finalists were born.

FloorThe final for Men's Floor Exercise took place on October 15. Marian Drăgulescu had qualified in 2nd, but pulled out of the competition on the morning of the final. As the first reserve, Jake Dalton took his place. There was also an inquiry made by the Japanese coaches into the scoring when Kōhei Uchimura's difficulty score was only awarded a 6.500 because they had mistaken a triple twisting move for a double twisting move. The inquiry was accepted by the judges, and the score adjusted accordingly, which gave Uchimura the gold medal.
