Size It Up answer: October 2
The five Mixed silhouettes for October 2, 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 29 ran from a toy building brick (3.18 cm) to the Hindenburg (245 m). The widest gap was round 2, Narwhal against Big Boy Locomotive, at 8.8×; the closest call was round 4, Gateway Arch against Hindenburg, only 1.3× apart — the kind of round that separates a 90 from a 60.
