DAILY NO. 2 · VERIFIED MEASUREMENTS

Size It Up answers – September 23, 2026

The September 23, 2026 puzzle ran from a Velociraptor at 2 m to a Triceratops at 9 m — about 5× apart, drawing on dinosaurs. The pair furthest apart was round 3: an Allosaurus is about 1.3× smaller than an American school bus.

Puzzle #2 asked about a Triceratops, a Pteranodon wingspan, an Allosaurus, a Velociraptor and an Ankylosaurus. Each answer below gives the measured size, the reference it stood beside and the source behind the number. Want the surprise first? Replay this puzzle — archived days never touch your streak.

ROUND 1

How long is a Triceratops compared with a Stegosaurus?

Answer: Triceratops — 9 m. A Triceratops measures 9 m (length / span), which is almost exactly the same size as the reference, a Stegosaurus at 9 m.

The skull alone could reach 2.5 m, among the largest of any land animal.

Common miss: players tend to inflate a Triceratops when it sits beside a Stegosaurus — big things get squeezed, small familiar things get stretched.

ROUND 2

How wide is a Pteranodon wingspan compared with an American pickup truck?

Answer: Pteranodon Wingspan — 6 m. A Pteranodon wingspan measures 6 m (length / span), which is almost exactly the same size as the reference, an American pickup truck at 5.9 m.

Measured across the wings — a span no living bird comes close to.

Common miss: players tend to compress a Pteranodon wingspan when it sits beside an American pickup truck — big things get squeezed, small familiar things get stretched.

ROUND 3

How long is an Allosaurus compared with an American school bus?

Answer: Allosaurus — 8.5 m. An Allosaurus measures 8.5 m (length / span), which is about 1.3× smaller than the reference, an American school bus at 10.7 m.

The common large predator of its day: far more Allosaurus fossils exist than T. rex ones.

Common miss: players tend to inflate an Allosaurus when it sits beside an American school bus — big things get squeezed, small familiar things get stretched.

How long is a Velociraptor compared with an adult horse?

Answer: Velociraptor — 2 m. A Velociraptor measures 2 m (length / span), which is about 1.2× smaller than the reference, an adult horse at 2.4 m.

Real Velociraptors were closer to turkey-sized than movie monsters.

ROUND 5

How long is an Ankylosaurus compared with a Triceratops?

Answer: Ankylosaurus — 8 m. An Ankylosaurus measures 8 m (length / span), which is about 1.1× smaller than the reference, a Triceratops 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 Triceratops — big things get squeezed, small familiar things get stretched.
