Zoom out from an average adult to a Boeing 737

A Boeing 737 is too big to show next to an average adult in one picture, so here it is in 2 steps. Each step is drawn to its own scale and zooms out from the step before.

  1. Step 1 of 2 Human → Megalodon

    A megalodon is about 8.6–15 times as long as an average adult is tall.

  2. Step 2 of 2 Megalodon → Boeing 737

    A Boeing 737 is about 1.6–2.6 times as long as a megalodon.

About the Boeing 737

The Boeing 737 is a twin-engine, single-aisle airliner family; the 737 MAX series, with CFM LEAP-1B engines and dual-feather Advanced Technology winglets, is its latest generation. Boeing's airport planning document gives the 737-8 an overall length of 129 ft 6 in (39.47 m) and a wingspan of 117 ft 10 in (35.92 m). It seats 178 passengers in a typical two-class layout and can take off at up to 182,200 lb.

  • The 737-8 seats 178 passengers in a two-class layout or 189 in a single class. [1]
  • The 737 MAX family covers the 737-7, 737-8, 737-8-200, 737-9, 737-10 and Business Jet versions, all powered by CFM LEAP-1B engines. [1]
  • The 737 MAX remains an FAA Airplane Design Group III and ICAO Aerodrome Reference Code C aircraft, the same airport category as earlier 737s. [1]

How many fit?

  • ≈ 23 × Human · height lined up end to end match the Boeing 737 · length
  • ≈ 800–1,100 × Human · body mass on the scales weigh as much as Boeing 737 · maximum takeoff weight
  • ≈ 1.6–2.6 × Megalodon · maximum length (estimates) lined up end to end match the Boeing 737 · length

Counts divide one sourced figure by another. "End to end" uses each object's main measurement; weight and volume rows appear only when both figures are sourced.

How it compares

  • 23× A Boeing 737 is about 23 times as long as an average adult is tall. See side by side
  • 1.6–2.6× A Boeing 737 is about 1.6–2.6 times as long as a megalodon. See side by side
  • 1.4× A Boeing 737 is about 1.4 times as long as an NBA basketball court. See side by side

  • 1/2.4 Big Ben is about 2.4 times as tall as a Boeing 737 is long. See side by side

Factors compare the length of a Boeing 737 with each object’s own main measurement (height for a human). Where a size varies, the factor is given as a range.

Notes on these figures

  • All figures are for the 737-8 (737 MAX 8). Other 737 versions range from shorter (737-7) to longer (737-10), and older generations differ.
  • Length, wingspan and fuselage length were read from Boeing's general-dimensions drawing (section 2.2.2), which Boeing says is accurate within +/- 6 inches.
