ALL ANSWERS · LANDMARKS · DAILY No. 46 · OCTOBER 19, 2026
Size It Up Landmarks answer: October 19
The five Landmarks silhouettes for October 19, 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 46 ran from the Space Needle (184 m) to the Minami Bisan-Seto Bridge Main Span (1.1 km). The widest gap was round 4, Space Needle against Brooklyn Bridge, at 2.6×; the closest call was round 2, Tokyo Skytree against Burj Khalifa, only 1.3× apart — the kind of round that separates a 90 from a 60.
