Size It Up answer: October 18
The five Mixed silhouettes for October 18, 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 45 ran from a tardigrade (0.5 mm) to an Airbus H135 (12.26 m). The widest gap was round 1, Interior Door against Airbus H135, at 6.0×; the closest call was round 3, Raccoon against Common Raven, only 1.8× apart — the kind of round that separates a 90 from a 60.
