Boeing 737 and Boeing 757 are single-aisle, twinjet aircraft manufactured by Boeing Company. Boeing- 737 came into service in 1965, whereas Boeing 757 completed its first maiden flight in 1982. It is not easy to differentiate between both aircraft; however, some technical aspects make them separable from each other.
On the other hand, capacity and range are other factors that draw a line between these air jets. Boeing-737 had four generations, while Boeing 757 had two variants. Therefore, it is better to compare the variants of aircraft.
Boeing 737 is a single-aisle aircraft that originated in the United States, manufactured by Boeing Company at its Renton Factory in Washington. Before it, the name Boeing was inseparable from enormous multiengine stream planes; therefore, in 1965, the organization declared its new advertisement twin jet, the Boeing-737, the more modest twinjet; designed to boost the 727 and 707 aircraft on shorter and narrower routes.
To save creation time and get the plane available quickly, Boeing gave the 737 a similar upper projection fuselage as the 707 and 727, so similar upper deck freight beds could be utilized for each of the three planes.
This twinjet includes the 707-fuselage cross-section and nose with two underwings turbofans engine. Because it was as long as it was wide, the 737 was dubbed the “square” plane from the start.
The initial 737-100 was developed in 1964, sent off without precedent in April 1967, and entered administration with the Lufthansa in 1968. By April 1968, the 737-200 was broadened and placed into administration. It had more than four generations, with various varieties obliging 85 to 215 travelers.
The Boeing 737 had six side-by-side seating- a selling point this way, it could accommodate more travelers per load. The number of seats was increased by mounting the engines under the wings.
This proper arrangement of motors cushioned a portion of commotion, declined vibration, and made it simpler to keep up with the plane at ground level.
Compared with the previous 727 jetliners, the medium-range Boeing757 twinjet was designed with the specification of 80% more fuel-efficient. It replaced 727 while retaining the short-field performance of 727.
The 757-200 had a range of about 3,900 nautical miles and could accommodate up to 228 passengers (7,222 kilometers). This prototype rolled off the assembly line in Renton, Washington, and completed its first official flight on February 19, 1982.
On March 29, 1991, a 757 lifted off, orbited, and landed at the 11,621-foot-high (3542-meter-high) Gong Gar Airport in Tibet, fueled by only one of its motors. Despite the runway being in a deep gorge surrounded by mountains more than 16,400 feet (4998 meters) high, the plane flew flawlessly.
The Boeing 757-300 was sent off by the organization in 1996. It could accommodate 280 passengers and had a 10% cheaper seat-mile operating cost than the 757-200. In 1999, the first Boeing 757-300 was delivered. Boeing had transported over 1,000757 jets by that time.
Boeing agreed to terminate production of its 757 aircraft in late 2003 because the improved capabilities of the most current 737s and the new 787 met the needs of the 757 market. On April 27, 2005, Boeing delivered the final 757-passenger plane to Shanghai Airlines, capping a remarkable 23-year service.
The following video will further shed light on the differences between the two.
Since Boeing 737 had four generations and the 757 had two variants, it’s complicated to compare both. However, a comparison of variants of both aeroplanes is possible. Both are single-aisle and 3-by-3 seating planes.
The Boeing 737 is smaller, shorter, and has engines that are smaller, thicker, and rounder. It has a cone-like snout.
A Boeing 757 is significantly longer. It features a narrower, more pointed nose, as well as more extended, thinner engines that grow smaller as they go back.
Even though the 737 has expanded in size over time, the 737 and 757 are still in distinct size classifications. ETOPS certification is possible for both aircraft, although the 757 is more commonly utilized for lengthy trips.
When the Boeing 757 was introduced, the classic variant of the 737 was current.
Boeing 737-400 | Boeing 757-200 |
146 passengers | 200 passengers |
119 feet in length | 155 feet in length |
Wingspan;95 feet | 125-foot Wingspan |
1135 sq. ft. of wing space | 1951 sq. ft. of wing space |
MTOW (maximum take-off weight): 138,000 lb. | MTOW (maximum take-off weight): 255,000 lb |
Eight thousand feet is the maximum take-off distance. | Six thousand five hundred feet is the maximum take-off distance |
2160 nm is the wavelength range. | 4100 nm is the wavelength range. |
2x 23,500 lbs. thrust | 2x 43,500 lbs. thrust |
Maximum fuel capacity: 5,311 US gallons. | Maximum fuel capacity: 11,489 US gallons. |
The Boeing 757 was 35 feet more in length than the Boeing 737, accommodated 50 more travelers, and flew twice farther.
The first variant of the Boeing 757 was bigger and had a greater capacity to accommodate more passengers than the classic variant of the Boeing 737.
Analyze the maximum departure load (MTOW) of the planes. Although the 757-200 just conveyed a 33% more significant number of individuals than the 737-400, it had an 85 % more noteworthy MTOW, permitting it to convey over two times more fuel. The Boeing-737 is much more valuable for shorter and busy routes, while the Boeing-757 can be utilized on longer distances, busier routes.
The Boeing 757 quickly takes edge over the 737 in terms of range and passengers. It easily crosses oceans and seas. The Boeing 737 is slowly encroaching on the market of the 757, trying to compete in the range and number of passengers, but the 737 stays behind the 757 in terms of distance.
Both versions were upgraded in the 1990s. The 737 was considerably improved, with new wings and a new engine, resulting in enhanced efficiency.
The following table shows a comparison between the two.
Boeing 737 (NG) | Boeing 757-300 |
180 passengers | 243 passengers |
138 feet in length | 178-foot length |
117-foot wingspan | 125 feet wingspan |
MTOW(maximum take-off weight): 187,700 lbs. | Maximum take-off weight: 272,500 lbs. |
Distance to take-off: 9,843 feet. | Distance to take-off: 7,800 feet |
3235 nm(nanometers) is the wavelength range | 3595 nm is the wavelength range |
2×28,400 lbs. thrust | 2×43.500 lbs thrust |
Maximum fuel capacity: 7,837 US gallons | Maximum fuel capacity: 11,489 US gallons. |
Although the Boeing 737’s increased efficiency brings its range closer to the 757, the 757 remains much bigger.
