The South American country, which is hosting the finals next year, has a law stating that at least one per cent of seats in each stadium are made available for disabled fans.
Obesity counts as a disability in Brazil, meaning it is the “first time tickets for obese people are offered at a FIFA event”, world football’s governing body said.
The same rules will apply to this summer’s Confederations Cup in Brazil.
"FIFA is generally following local legislation of the host countries, and is in Brazil guided by the general FIFA World Cup bill and a separate (Brazilian) decree related to obese people," FIFA told the Associated Press.
"The number of tickets available for disabled people depends on the infrastructure provisions of each stadium and the distribution between seats."
Fans thinking of overeating in an attempt to get priority seating should exercise caution though – fatties will need to provide a medical certificate proving they have a Body Mass Index of higher than 30.
