The verdict
Which is actually bigger?
Same manufacturer, same job description, twenty years apart. The 777 is bigger in every dimension and carries far more people; the 787 flies nearly as far on dramatically less fuel and opened routes too thin for a 777 to ever fill. It is the clearest illustration on this site of what composites and modern engines actually bought aviation — not more speed, not more size, but more range per seat.
The Boeing 777 is the longer of the two, at 73.86 m against 68.28 m — a difference of 5.58 m. It also has the greater wingspan, 4.68 m wider, so it is the bigger aircraft on both measures.
The world's largest twinjet — the long-haul workhorse. The aircraft that reinvented long-haul economics. The silhouettes above are drawn at true relative scale from the sourced figures on each aircraft's page — same metres, same pixels, no artistic licence.
On capacity, the Boeing 777 carries more people in a typical layout — 396 against 336.
