Burger King is currently facing a class-action lawsuit alleging false advertising related to the size and amount of ingredients in its signature Whopper sandwich. The lawsuit, filed in 2022 and representing 19 plaintiffs from 13 states, claims that Burger King's advertisements depict the Whopper as approximately 35% larger and containing more than double the meat than what customers actually receive. The plaintiffs argue that since 2017, Burger King's marketing materials have exaggerated the size of the Whopper, showing oversized patties and ingredients spilling over the bun, while the actual product served has not changed in size or quantity of ingredients
. Burger King has denied these claims, stating that the flame-grilled beef patties used in advertising are the same as those served in restaurants and that the differences in appearance are due to the hand-made nature of each burger and common food styling practices to make items look more appealing
. However, a federal judge in Florida, U.S. District Judge Roy Altman, denied Burger King's motion to dismiss the lawsuit in May 2025, ruling that the plaintiffs' claims go beyond mere advertising puffery and allowing the case to proceed. The judge found it plausible that reasonable consumers could be deceived by the advertisements and allowed claims of negligent misrepresentation to move forward
. The outcome of this case could have broader implications for advertising standards in the fast-food industry, as similar lawsuits have been filed against other chains like McDonald's and Wendy's for comparable false advertising allegations
