Boeing 737 Vs 757: A Comprehensive Comparison

When it comes to commercial aviation, two aircraft that have left an indelible mark on the industry are the Boeing 737 and 757. Both are highly efficient and versatile aircraft in their respective categories, and have fundamentally altered the way people travel.

In this article, we’ll take a deep dive into the differences between the Boeing 737 and 757, touching upon their specifications and design considerations. The aim is to provide potential travelers with a comprehensive understanding of both aircraft, helping them make informed decisions about their travel plans.

Boeing 737 Vs 757: Overview and History

The Boeing 737 and 757 were designed and developed by the Boeing Company in the 1960s and 1980s, respectively. The Boeing 737 was first introduced in 1967 and has since become the most popular commercial aircraft in the world due to its efficient size and fuel economy. The 757, on the other hand, was developed in the 1980s as a complete redesign of the 727, which was becoming increasingly outdated.

Boeing 737 Vs 757: Specifications

The Boeing 737 and 757 differ in terms of their size, range, capacity, and speed.

The Boeing 737-800 has a length of 129 ft and an overall wingspan of 112 ft, while the 757-200 has a length of 155 ft and a wingspan of 124 ft. The design difference is noticeable, but both aircraft have been designed to be highly efficient and reduce drag.

The 737-800 has a capacity of 162-189 passengers, while the 757-200 can carry up to 295 passengers. The 757 can also be configured for mixed classes such as business and economy, whereas the 737 is typically used for single-class service.

The 737-800 has a range of 3,115 nautical miles, making it suitable for short to medium-haul flights. The 757-200, on the other hand, has a range of 4,100 nautical miles, making it an ideal choice for transatlantic flights.

The 737-800 has a cruising speed of 530 mph, while the 757-200 has a cruising speed of 540 mph. The difference is negligible and both flights are well suited for reaching their respective destinations.

Boeing 737 Vs 757: Design and Performance

Both the 737 and 757 are built with modern design principles and innovative features, which make them highly efficient and reliable.

The Boeing 737 and 757 have distinctively different wings; the 737 has a narrow wing while the 757 has a wide one. The narrow wing on the 737 allows for it to fly at slower speeds and still maintain lift, whilst the wide wing on the 757 allows it to fly faster and with greater lift.

The Boeing 737 was designed for fuel efficiency and versatility, making it an excellent choice for airlines operating in high-density markets. It has a better fuel economy than the 757, which enables airlines to serve smaller airports that the 757 cannot serve.

The 757, on the other hand, was designed for longer distances and higher speeds, making it a popular aircraft for transatlantic and intercontinental routes. It has a higher thrust engine, longer fuselage length, higher wings that allow it to take off and land on shorter runways, or challenging ones like those of small, remote airports.

Boeing 737 Vs 757: Economical Considerations

Airlines, just like any business, prioritize cost-efficiency as one of their main objectives. They’ll therefore be more inclined to choose aircraft that guarantee great fuel efficiency, minimal maintenance costs, and maximum passenger capacity.

Fuel Efficiency:
The 737 has a better fuel economy per seat-mile (ASM) as compared to the 757.

Maintenance Costs:
Maintenance costs are reasonable for both aircraft, but the 737 has a slight edge because of its smaller size and fewer parts.

The Boeing 757 has a larger passenger capacity than the 737, which is well-suited for airlines trying to manage high passenger traffic. However, the 737’s smaller size makes it versatile, allowing it to operate more frequent flights in high-density markets.


Both the Boeing 737 and 757 have distinctly different yet highly efficient features that make them popular choices for airlines in their respective segments. The 737 is highly efficient for short to medium-haul flights, with reduced fuel consumption and operating costs, while the 757 is built for long-haul flights with high-speed capabilities and passenger capacity. In the end, each airline will choose the aircraft that matches their specific needs, based on capacity requirements, costs, and environmental factors.
