Seat legroom refers to the amount of space between a passenger's seat and the back of their knees when they are seated comfortably. It is an important factor in determining whether or not passengers can enjoy a comfortable flight, especially on long-haul flights where sitting for extended periods can be uncomfortable without adequate legroom. Seat pitch refers to the distance between one point on a seat to another point of the same type of seat in front of it. Generally speaking, more legroom is desirable and provides greater comfort during travel.
