The average weight of a single lettuce head varies depending on the variety and growing conditions. Iceberg lettuce, a common type, typically weighs between 500 and 700 grams. Romaine, butterhead, and other varieties can range from 300 to over 1000 grams. Factors influencing weight include maturity at harvest, water content, and agricultural practices.
Understanding the typical weight range is valuable for several reasons. In culinary settings, accurate portioning and recipe scaling depend on consistent ingredient weights. For growers and distributors, weight is a crucial factor in pricing, packaging, and yield calculations. Consumers, too, benefit from understanding typical weights to make informed purchasing decisions and minimize food waste. Historically, the weight of produce has played a role in trade and commerce, highlighting its enduring significance.
