Seat pitch refers to the distance between a point on one seat and the same point on the seat in front of it. This measurement is typically taken in inches and is an important factor in determining passenger comfort on an aircraft. A greater seat pitch generally allows for more legroom, making it easier for passengers to sit comfortably during flights. Airlines often vary their seat pitch depending on the type of aircraft and the class of service. For example, economy class seats usually have a smaller seat pitch compared to business class or first class seats, which offer more space for passengers.
