Burger King is facing a class-action lawsuit alleging that the company misleads its customers by making its Whopper burgers appear larger on its posters than they actually are.

A lawsuit originally filed in March 2020 against the fast-food chain claims that Burger King gives its customers Whoppers 35% smaller than they advertise.

"Burger King advertises its burgers as large burgers compared to competitors and containing oversized meat patties and ingredients that overflow over the bun," says the document that criticizes the company for not complying with what they promote.

The restaurant chain tried to dismiss the lawsuit on the grounds that the company is not obliged to guarantee that the actual product is exactly as advertised.

A district judge in Miami named Roy Altman recently ruled, that while the restaurant chain certainly doesn't promise any burger size or weight in its ads, Burger King can be sued for negligence and unjust enrichment, allowing the company to face a court battle to let a jury decide.

Burger King isn't the only restaurant chain facing these kinds of lawsuits. Last year, McDonald's and Wendy's were also sued for having misleading commercials.

Taco Bell is also facing a lawsuit of more than $5 million for selling pizzas and wraps that allegedly contain only half the filling of what they show in their ads.
