The World's largest pumpkin is the size of an adult walrus
Farming towns across the country host annual giant pumpkin weigh-off competitions, inspiring growers to invest their time and money into feeding massive gourds. About 125 giant pumpkin contests are held each year, but the Half Moon Bay World Championship is referred to as "the Super Bowl" of pumpkin weigh-off competitions.
Last year, Travis Gienger, a horticulture and landscape teacher at Anoka Technical College, grew a 2,749 pound pumpkin, breaking the world record for plumpest pumpkin on the planet. Gienger won the Half Moon Bay pumpkin weigh-off three years in a row. In 2024, his giant pumpkin weighed in at 2,471 pounds.
The festival in Half Moon Bay, located south of San Francisco, draws tens of thousands of visitors. Winners of the pumpkin weigh-off competition are paid $9 per pound or $30,000 for breaking a world record.
How much do giant pumpkins weigh?
A pumpkin is considered giant if it weighs over 150 pounds. Axios reported that some giant pumpkins can grow up to 50 pounds per day if the conditions are favorable. Once these pumpkins are cut from their vines they can lose 6 to 8 pounds a day.
Giant pumpkins can grow over 2,000 pounds. According to an online Alaska Wild fact sheet, Gienger's 2023 winning pumpkin was the equivalent weight of an adult male walrus.
Nick Kennedy, the second place champion from the 2023 Half Moon Bay weigh-off, compared his pumpkin's size – 7 feet by 6½ feet and about 45 inches tall – to a Smart car. This type of car can measure as little as 8½ feet by 5½ feet and 61 inches in height.
Giant pumpkins continuously break records
More than 50 years ago, the winning pumpkin from the Half Moon Bay Championship weighed 132 pounds. Since the competition began in 1974, pumpkins have steadily increased in size. In 2023, the winning pumpkin had increased in weight by nearly 2000% compared to 1974 winning pumpkin.
History of pumpkin weigh-off competitions
Jack La Rue, a former competitive grower who’s now a historian and statistician for the Great Pumpkin Commonwealth – the international ruling body for weigh-off contests – said the pursuit of record-setting pumpkins dates back to at least the late 1800s.
At the 1900 world’s fair in Paris, William Warnock set the recognized mark at 400 pounds, and topped it by three pounds in 1904. That record stood for 72 years until Bob Ford smashed it with a 451-pound gourd. In 1980, Canadian Howard Dill gave the movement a major push when he set one of his three world records with a 459-pound pumpkin the year after developing the Dill’s Atlantic Giant Pumpkin seeds.
The Half Moon Bay weigh-off began in 1974, when the California town barely edged out Circleville, Ohio, in an amiable contest for the fictitious title of pumpkin capital of the world.
The competition from other sites has increasingly gotten tougher, but La Rue said he still ranks Half Moon Bay as the leading contest, kept aloft by hosting the current world mark set by Gienger.
“Right now, Half Moon Bay stands on top of the world for the heaviest 10 pumpkins (on average) ever weighed at one site,’’ La Rue said.
