Size It Up answer: September 15

The five Mixed silhouettes for September 15, 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 12 ran from a coffee mug (9.5 cm) to Mount Everest (8.849 km). The widest gap was round 5, Hindenburg against Cargo Van, at 41×; the closest call was round 1, Coffee Mug against House Sparrow, only 1.7× apart — the kind of round that separates a 90 from a 60.

  1. ROUND 1

    Coffee Mug vs House Sparrow

    House Sparrow · reference · 16 cm
    Coffee Mug · true height · 9.5 cm

    1.7× shorter than the house sparrow

    A standard coffee mug is about 9.5 cm tall.

  2. ROUND 2

    Big Ben (Elizabeth Tower) vs Blue Whale (Average Adult)

    Blue Whale · reference · 27 m
    Big Ben · true height · 96 m

    3.6× taller than the blue whale

    The clock tower is 96 m tall; Big Ben is strictly the 13.7-tonne bell inside it.

  3. ROUND 3

    Nuclear Submarine (Ohio class) vs Eurostar e320 (complete 16-car train)

    Eurostar e320 · reference · 400 m
    Nuclear Submarine · true length · 170 m

    2.4× shorter than the Eurostar e320

    An Ohio-class submarine is 170 m long — longer than the Washington Monument is tall.

  4. ROUND 4

    Mount Everest (above sea level) vs Golden Gate Bridge (total length)

    Golden Gate Bridge · reference · 2.737 km
    Mount Everest · true height · 8.849 km

    3.2× taller than the Golden Gate Bridge

    Everest is 8,849 m above sea level — airliners cruise only a little higher.

  5. ROUND 5

    Hindenburg vs Cargo Van (long-wheelbase panel van)

    Cargo Van · reference · 5.98 m
    Hindenburg · true length · 245 m

    41× longer than the cargo van

    The Hindenburg was 245 m long — nearly as long as Titanic.
