Legroom refers to the amount of space available for a person's legs when seated, particularly in vehicles like airplanes, cars, and buses. It is an important factor for comfort, especially during long journeys. Insufficient legroom can lead to discomfort and fatigue, making travel less enjoyable. In the context of air travel, legroom is often measured in inches and varies by airline and seating class. Economy class typically offers less legroom compared to business class or first class. Passengers may choose seats with more legroom for added comfort, especially on longer flights.
