Seat pitch refers to the amount of space available to passengers between each row of seats on an airplane, train, or bus. When it comes to travel, the comfort of a passenger is often directly related to the seat pitch measurement. An alternative term for seat pitch could be "legroom." Another synonym often used is "seat spacing" which refers to the distance between the back of one seat to the back of another. "Toe room" or "foot space" might also be used to describe the amount of space a passenger has to rest their feet. Other terms used include "knee space" or "knee room," which refers to the distance between the seat in front and the passenger's knees. Ultimately, all these terms are used interchangeably and refer to the comfortable seating space provided to passengers.
