ALL ANSWERS · LANDMARKS · DAILY No. 58 · OCTOBER 31, 2026
Size It Up Landmarks answer: October 31
The five Landmarks silhouettes for October 31, 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 58 ran from Al-Khazneh (39.5 m) to the Burj Khalifa (828 m). The widest gap was round 1, Palace of Culture and Science against Burj Khalifa, at 3.5×; the closest call was round 2, Ben Franklin Bridge Main Span against Merdeka 118, only 1.3× apart — the kind of round that separates a 90 from a 60.
