DAILY NO. 4 · VERIFIED MEASUREMENTS
The five dinosaurs objects from the Size It Up puzzle on September 4, 2026, with the measured size of each, the reference it was compared against, a source you can check, and how the community's guesses landed. Want the surprise first? Replay this puzzle — archived days never touch your streak.
Answer: an Iguanodon measures 10 m (length / span), which is about 1.2× smaller than the reference, a Tyrannosaurus rex at 12.3 m.
Its thumb spike was first reconstructed, wrongly, as a horn on the nose.
Common miss: players tend to inflate an Iguanodon when it sits beside a Tyrannosaurus rex — big things get squeezed, small familiar things get stretched.
Answer: an Ankylosaurus measures 8 m (length / span), which is about 1.1× smaller than the reference, a Stegosaurus at 9 m.
The tail club weighed tens of kilos and could swing hard enough to break bone.
Common miss: players tend to inflate an Ankylosaurus when it sits beside a Stegosaurus — big things get squeezed, small familiar things get stretched.
Answer: a Pteranodon wingspan measures 6 m (length / span), which is about 1.5× smaller than the reference, a Triceratops at 9 m.
Measured across the wings — a span no living bird comes close to.
Common miss: players tend to inflate a Pteranodon wingspan when it sits beside a Triceratops — big things get squeezed, small familiar things get stretched.
Answer: a Velociraptor measures 2 m (length / span), which is almost exactly the same size as the reference, a queen bed at 2 m.
Real Velociraptors were closer to turkey-sized than movie monsters.
Common miss: players tend to inflate a Velociraptor when it sits beside a queen bed — big things get squeezed, small familiar things get stretched.
Answer: a Tyrannosaurus rex measures 12.3 m (length / span), which is 1.1× as big as the reference, an American school bus at 10.7 m.
A large T. rex reached around 12.3 metres long.
Common miss: players tend to compress a Tyrannosaurus rex when it sits beside an American school bus — big things get squeezed, small familiar things get stretched.
