Seat pitch refers to the distance between a point on one seat, such as the front edge, and the same point on the seat in front or behind it. It is a measurement used in the airline industry to determine the amount of legroom provided to passengers. A greater seat pitch generally indicates more legroom, while a smaller seat pitch means less legroom. Seat pitch is an important factor for passenger comfort, especially on longer flights, and can vary depending on the airline, aircraft type, and class of service.
