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.
