The weight of a passenger plane varies drastically by its category and size. A "narrow-body" workhorse like the Airbus A320 or Boeing 737 typically has an empty weight of approximately 90,000 lbs (41,000 kg) and a Maximum Takeoff Weight (MTOW) of roughly 170,000 to 200,000 lbs. Moving into the "wide-body" class, a Boeing 777-300ER has an MTOW of a staggering 775,000 lbs (351,000 kg). The world's largest passenger airliner, the Airbus A380, holds the record with a maximum weight of over 1.2 million lbs (575,000 kg) when fully loaded with fuel, passengers, and cargo. On the smaller end of the spectrum, light aircraft like the Cessna 172 weigh only about 1,600 lbs empty. These weights are meticulously managed in 2026 using digital sensors and real-time fuel monitoring, as every extra pound significantly impacts the aircraft's fuel efficiency and center of gravity during the critical phases of takeoff and landing.
