Day 12 ran from the Arc de Triomphe (50 m) to the Tokyo Skytree (634 m). The widest gap was round 5, Arc de Triomphe against Great Pyramid of Giza, at 4.6×; the closest call was round 3, Brooklyn Bridge against Shanghai Tower, only 1.3× apart — the kind of round that separates a 90 from a 60.

  1. ROUND 1

    Tokyo Skytree vs Petronas Tower 1 (one tower, architectural height)

    Petronas Tower 1 · reference · 452 m
    Tokyo Skytree · true height · 634 m

    The Shard · reference · 309.6 m
    Colosseum · true length · 189 m

  3. ROUND 3
