Size It Up Landmarks answer: October 11

The five Landmarks silhouettes for October 11, with the true sizes. If you have not played yet, this page is a spoiler — play these five first, then come back to argue with the numbers.

Day 38 ran from the Brandenburg Gate (26 m) to the Akashi Kaikyo Bridge Main Span (1.991 km). The widest gap was round 4, Akashi Kaikyo Bridge Main Span against Lotte World Tower, at 3.6×; the closest call was round 1, Leaning Tower of Pisa against National Monument (Monas), only 2.3× apart — the kind of round that separates a 90 from a 60.

  1. ROUND 1

    Leaning Tower of Pisa (high side) vs National Monument (Monas) (monument with flame)

    National Monument (Monas) · reference · 132 m
    Leaning Tower of Pisa · true height · 57 m

    2.3× shorter than the National Monument (Monas)

    The Leaning Tower is 57 m on its high side and leans about 4 degrees.

  2. ROUND 2

    Empire State Building (to the tip) vs Golden Gate Bridge (main span only)

    Golden Gate Bridge · reference · 1.28 km
    Empire State Building · true height · 443 m

    2.9× shorter than the Golden Gate Bridge

    The Empire State Building is 443 m to the tip of its antenna; the roof sits at 381 m.

  3. ROUND 3

    Tower Bridge (central span only) vs Brandenburg Gate (with the quadriga)

    Brandenburg Gate · reference · 26 m
    Tower Bridge · true length · 61 m

    2.3× longer than the Brandenburg Gate

    Tower Bridge: 61 m length (central span only). Central span between the two towers; not the full length of the bridge.

  4. ROUND 4

    Akashi Kaikyo Bridge Main Span (between tower centres · schematic) vs Lotte World Tower (height, rounded)

    Lotte World Tower · reference · 555 m
    Akashi Kaikyo Bridge Main Span · true length · 1.991 km

    3.6× longer than the Lotte World Tower

    Akashi Kaikyo Bridge Main Span: 1991 m length (between tower centres · schematic). Horizontal main span between the two tower centre lines; approach roads and side spans excluded. Tower heights, deck depth and cable details are schematic, not measured.

  5. ROUND 5

    Washington Monument vs Petronas Tower 1 (one tower, architectural height)

    Petronas Tower 1 · reference · 452 m
    Washington Monument · true height · 169 m

    2.7× shorter than Petronas Tower 1

    The Washington Monument is 169 m — the world's tallest stone structure.
