Size It Up answers – September 22, 2026

The September 22, 2026 puzzle ran from a road bicycle at 1.8 m to a Boeing 747 at 70.7 m — about 40× apart, drawing on vehicles. The pair furthest apart was round 5: a Boeing 747 is 1.9× as big as a Space Shuttle orbiter.

Puzzle #1 asked about a road bicycle, an American pickup truck, an American school bus, a farm tractor and a Boeing 747. 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 road bicycle compared with a Velociraptor?

Answer: Road Bicycle — 1.8 m. A road bicycle measures 1.8 m (length / span), which is about 1.1× smaller than the reference, a Velociraptor at 2 m.

A road bike’s wheelbase is barely a metre; the wheels themselves add the rest.

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

ROUND 2

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

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

A full-size pickup can be nearly six metres long.

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

ROUND 3

How long is an American school bus compared with a Stegosaurus?

Answer: American School Bus — 10.7 m. An American school bus measures 10.7 m (length / span), which is 1.2× as big as the reference, a Stegosaurus at 9 m.

A full-size American school bus is commonly around 10.7 metres long.

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

ROUND 4

How long is a farm tractor compared with a family sedan?

Answer: Farm Tractor — 5 m. A farm tractor measures 5 m (length / span), which is 1.1× as big as the reference, a family sedan at 4.6 m.

Five metres of tractor is mostly wheelbase; the rear tyres alone can stand taller than an adult.

Common miss: players tend to compress a farm tractor when it sits beside a family sedan — big things get squeezed, small familiar things get stretched.

ROUND 5

How long is a Boeing 747 compared with a Space Shuttle orbiter?

Answer: Boeing 747 — 70.7 m. A Boeing 747 measures 70.7 m (length / span), which is 1.9× as big as the reference, a Space Shuttle orbiter at 37.3 m.

A classic Boeing 747 is roughly 70.7 metres long.

Common miss: players tend to compress a Boeing 747 when it sits beside a Space Shuttle orbiter — big things get squeezed, small familiar things get stretched.
