Size It Up answer: July 29

The five Mixed silhouettes for July 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.

This pre-launch puzzle ran from a tennis ball (6.7 cm) to Earth (12,740 km). The widest gap was round 1, Tennis Ball against European Rabbit, at 6.0×; the closest call was round 3, Holstein Cow against King-size Bed, only 1.2× apart — the kind of round that separates a 90 from a 60.
