Size It Up Landmarks answer: October 4
The five Landmarks silhouettes for October 4, 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 31 ran from the Horyuji Five-storied Pagoda (32.5 m) to the Tokyo Skytree (634 m). The widest gap was round 4, Parthenon against Horyuji Five-storied Pagoda, at 2.1×; the closest call was round 3, Manhattan Bridge Main Span against Tokyo Skytree, only 1.4× apart — the kind of round that separates a 90 from a 60.
