Size It Up answer: October 12

The five Mixed silhouettes for October 12, 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 39 ran from a drink can (12.3 cm) to an Airbus A380 (72.7 m). The widest gap was round 5, Airbus A380 against Horse, at 30×; the closest call was round 4, Porsche 911 Carrera against Moai, only 1.1× apart — the kind of round that separates a 90 from a 60.

  1. ROUND 1

    Drink Can · true height · 12.3 cm

    1.3× shorter than the US dollar bill

    A twelve-ounce drink can stands 12.3 cm tall; the ounces measure what is inside it.
