Boeing 737 Specs

In the more than fifty years of its existence, the Boeing 737 has evolved from a stumpy little twin-jet airliner into a family of high performance and versatile jet transports. Check out the Boeing 737 Specs tables below to get a clear picture of how these city jets stack up.

The global climate of rising fuel costs, as well as increased competition in the form of the Airbus A320, have ensured that Boeing continues to bring out more improved versions of the type. Of course, we know that there have been major hiccups in the introduction of the new 737 MAX with the tragic loss of life as a result. Whatever the reason, we hope that both Boeing and the F.A.A. (Federal Aviation Administration) have cleaned up their act and made the MAX as safe an airliner as its predecessors.

Its all about family

The Boeing 737 has four distinct families of variants within the type. These are:

Family Variant
Original 737 100 737 200ADV
Classic 737-300 737-400 737-500
Next Generation (NG) 737-600 737-700 737-800 737-900
MAX MAX-7 MAX-9 MAX-200 MAX-9 MAX-10

  1. Why has Boeing maintained its designation to be B737, despite the latest B737 bears little resemblance to the original variant of the B737?

    1. Hi and thanks for stopping by. I suppose you have to look at the 737 as an aircraft class that is targeting a certain segment of the market. The Boeing 737 is designed to fill the smaller jet airliners space over a given range of seats. Whilst bigger than the Embraer E-Jets, Boeing feels this is an optimum size range for a small city jet which can also be used for medium-haul international services.

      If you look at your favourite model of car, you would see that they have also evolved over time to be something unrecognisable from their ancestors. Gains in technology as well as traveller expectations, continue to drive aeroplane makers to come up with improved, more cost efficient and more comfortable versions of their offerings.

        1. Hi Jeffrey,
          I’m not sure I understand the question. Are you after the radius of the fuselage at the level of the cargo door?
          Cheers Peter

    2. Lemuel Rodriguez

      Greetings. A family consultation. In which manual could you find the cross-sectional dimensions of the wing spars and stabilizer (737-300)
      You could support me with that.
      I already checked in the AMM, SRM.

  2. Do you have the estimated production material used for the 737 Next Gen? I know the 787 is moving toward using more composite materiel instead of aluminum. Is the same happening with the 737?

    1. Hi Shawn,

      it seems that Boeing has not leaped ahead with the 737 as much as they have with the 787. The use of composite materials in the 737 Next Gen or even the 737 Max is quite conservative. Aluminium alloys are still the mainstay of the construction materials used with various blends used according to the strength required for the particular component.

      For Example:
      Slats, flaps and Fuselage skin – areas primarily loaded in tension – Aluminium alloy 2024 (Aluminium and copper)

      Wing lower skin – Aluminium alloy 7055 (Aluminium, zinc, magnesium and copper)

      Wing ribs, Frames, stringers, keel and floor beams – Aluminium alloy 7075 (Aluminium and zinc)

      Spars, beams and Wing upper skin – Aluminium alloy 7178 (Aluminium, zinc, magnesium and copper)

      Landing gear beam – Aluminium alloy 7175 (Aluminium, zinc, magnesium and copper)

      I hope that helps.

      Cheers Peter

  3. Hi. I am looking for a wheelbase in one main shin and the pressure in the wheel ( Boeing 737-500)

    1. Hi and thanks for your question. For the wheels, I will give you two measurements. The wheelbase which is the distance from the nosewheel to the line between the main wheels, which is 11.07 metres. The wheel track, which is the distance between the main wheels is 5.25 metres. The nose wheel pressure in PSI is 186-194. The main wheel tyre pressures are 193-202, once again PSI.
      Happy Flying.

  4. Anumula Sai Pramod

    Hi. I am looking to build a prototype of Boeing 737 for numerical simulation purpose. Can you please tell me where to look for the cabin height,width, seat height, width and door to door length. from cockpit door to the kitchen alley .

    1. Hi Anumula,

      thank you for stopping by. I found this image that might have some of the answers you need. Click here.
      We’d love you to share what you build when you’re done. Best of luck.
      Cheers Peter

      1. Anumula Sai Pramod

        Thanks, peter!
        I started of using with this image. I will be very happy to share with you once I get decent results. My simulation is focused on postcrash fires. And I hope I will get some good stuff to post it to you

  5. Andre Renaldy Pandie

    hello, i would like to know about the technology which applied on B737 NG flight cockpit lay out include it’s characteristics (advantages and disadvantages), especially on PFD and MFD, can you tell me or send me a link which discuss about that?

    1. Hi Andrey,
      It sounds like you have a bit of a project on your hands. The information is surely out there, but maybe the questions need to be a bit more specific.
      Good luck.
      Cheers Peter

  6. Hello, do you know the meaning of the 737-8K5 designation and its background? The aircraft look like standard -800s, so why the difference?

    1. Hi Ben,
      You are right, it does look very much like a 737-800. That is because it is an 800. It is simply an 800 with certain modifications that might have been stipulated by the customer airliner. In this case I believe TUI fly is the main customer. We don’t actually have access to a table of these variants and their features. If anyone does, please feel free to share with us all.
      Thank you.
      Cheers Peter

      1. Peter

        Thank you for your reply. I cannot find any more information anywhere, but if I stumble across it, I will be sure to post it!


  7. Ana-Maria STOICA

    Hello! I would like to know what is the AOA during cruise for B737 NG and also the Fuel Flow cruise.

    1. Hi Anna-Maria,
      this question can have so many answers depending on the conditions, such as weight, air density, required speed etc. Maybe there is someone out there who can give you a better answer.
      Thanks for stopping by.
      Cheers Peter

  12. Hi,
    Is the Range with Max Payload NM(Km) wrong?
    At least with the Max 8, looking into the ACAP of Boeing (Rev E), I found it is 2500nm.
    I think in the table you are talking about the range where payload is limited by MTOW.
    Can you confirm if I’m right or wrong?
    Thank you so much

    1. Hi Josep,

      thank you for stopping by and we appreciate you checking us out on the details. You were right, there were some discrepancies around the range. We have rechecked with Boeing and the figure should now be up to date and correct.

      Cheers Peter

    1. Hi Mark,
      thanks for stopping by. As you can appreciate, the cockpit of any aircraft is always a non-standard shape. With the tapering of the aircraft nose, it is hard to give any one clear answer. what we have done is sourced a document that gives the various dimensions of a 737 cockpit with which you should be able to find your desired outcome.

      Perhaps you will build a cockpit and use it with the new Flight Sim 2020. 🙂

      Happy flying.


    1. Hi Aaron,

      thank you for stopping by. The data for our pages are sourced from various locations, ranging from airliner manufacturer websites, technical airliner manuals etc.

      Cheers Peter

      1. Hi Peter,
        Have you got any exact places or web address please? Just not sure how to access these.
        Thank you


  15. Hi, How can I learn aerospace materails about a and b basis allowables for Boeing-737 ? I am looking forward to your responses.
    Thanks now.

    1. Firstly, thank you for reply. For instance, What is the Aluminium alloy 7055 basis values ?

      1. Hi Mehmet,

        sorry that is way out of our knowledge here. Can we suggest copying and pasteing ” Aluminium alloy 7055 basis value” into your search engine of choice? There seem to be a lot of answers that come up, some of which might be what you’re looking for.

        Good luck.

        Cheers Peter

  16. Hiya,
    Just wondering, where did you get the information about what specific aluminium alloys are used on different parts of the aircraft? Are there any useful sources where I might find the exact materials used in other aircraft?

    1. Hi Henna,
      each aircraft is sourced from different places. Usually, you can find technical manuals, sometimes in PDF form which are full of information.
      Cheers Peter

  17. Hi there.. is anyone able to tell me the radius of the arc of the L1 and L2 doors as they are being opened? i.e..what is the maximum lateral distance the doors swing away from the aircraft, before they get to rest in the fully open position?

    1. Hi Bradley,
      thanks for stopping by. The VNE or never exceed speed for the Boeing 737-800 is 340 KIAS(Knots indicated airspeed) or Mach 0.82. Additionally, below 10,000 feet it should not exceed 250 knots.
      Cheers Peter

  18. Hi All,
    Perhaps somebody has experience in shipment of landing gear. i would like to know the dimension of both nose and main landing gear crates also the approximate weight of the shipment.
    Thank you.

  19. Hi
    I am looking for some spec information in more detail for a project
    could you point me in the right direction or tell me what the weight of the landing gear would be on a 737? Also looking for the materials used for the front windscreen?

  20. Hello

    I’m doing a dissertation on morphing wingtip devices, looking at varying the cant angle to maximise efficiency. Do you know how or where I would be able to get details on the dimensions or materials of the wingtip for this aircraft or other similar aircraft?

    Any help would be greatly appreciated and thank you for all your work it’s extremely helpful!
