Size It Up Landmarks answer: September 29

The five Landmarks silhouettes for September 29, 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 26 ran from the Leaning Tower of Pisa (57 m) to the Shimotsui-Seto Bridge Main Span (940 m). The widest gap was round 3, Hoover Dam against Leaning Tower of Pisa, at 3.9×; the closest call was round 5, Shanghai Tower against Ohnaruto Bridge Main Span, only 1.4× apart — the kind of round that separates a 90 from a 60.
