737 Family Identification Charts

737 family identification charts for spotters and curious passengers: our own unbranded drawings to count the overwing exits, judge the length, spot winglets and tell a 737NG from a 737 MAX, with flight-tracker type codes, a six-drawing same-scale practice quiz and an answer key.

What’s inside:

- Start here: four clues, in order

- Chart 1: count the overwing exits

- Chart 2: judge the length

- Chart 3: wingtips, with and without winglets

- Chart 4: under the wing

- Chart 5: 737NG or 737 MAX?

- Chart 6: flight-tracker type codes

- Practice: six mystery twinjets, drawn to the same scale

- Answer key and quick reference

- Credits, licence & sources

Pages: 11 (including cover and credits). Sizes: A4 (210 × 297 mm) and US Letter (8.5 × 11 in), both PDFs included in one zip.

Printing: Print at 100% / actual size on A4 or US Letter. Inside pages use light backgrounds and print well in black and white; covers are dark, so start from page 2 to save ink.

Every fact is checked against named source pages from Boeing, EASA, the FAA and the US Navy (checked 29 Oct 2026), and the sources are listed on the pack’s credits page. Figures that can change, such as Boeing’s current lengths and the FAA type codes, are printed with that date.

There are no photos in this pack: all drawings, puzzles and layouts are REALLYBYTE’s own work. Aircraft drawings are generic and unbranded, not scale plans, with no manufacturer or airline logos, liveries or markings. Not affiliated with or endorsed by The Boeing Company or any airline, nor by CFM International, the US Navy, EASA or the FAA. Boeing, 737 and other names are used only to identify the aircraft, engines and organisations discussed.

Licence: personal use. Print as many copies as you need for yourself and your household. Please don’t resell, re-upload or share it publicly. For club, school or commercial use, please email info@reallybyte.com.
