Size It Up answer: October 10
The five Mixed silhouettes for October 10, 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 37 ran from a SIM card (2.5 cm) to Denali (6.19 km). The widest gap was round 2, Pink Salmon against Pencil, at 3.3×; the closest call was round 4, Semi-Trailer Truck against Brachiosaurus, only 1.3× apart — the kind of round that separates a 90 from a 60.
