The largest pizza has a total surface area of 1,261.65 m² (13,580.28 ft²) and was prepared by Dovilio Nardi, Andrea Mannocchi, Marco Nardi, Matteo Nardi and Matteo Giannotte (all Italy) from NIPfood at Fiera Roma, in Rome, Italy, on 13 December 2012.

The pizza was named "Ottavia", a word of Roman origin for "eighth son", as a homage to the first Roman emperor Octavian Augustus, who represented an epoch-making change in the history of Rome and brought the Empire into a period of economic and cultural stability. Ottavia was 100% gluten-free.
