About Guess the Size

Guess the Size is a free browser game about how big things really are. Each round shows a familiar object at its real size next to a mystery object. Stretch the mystery object to the size you think it is, lock in your guess, then see the real size and your score.

Three ways to play

• Daily: the same 5 objects for everyone, with a new puzzle at local midnight.
• Unlimited: 10 random objects per run. Try to beat your best score.
• Duel: take on Sizebot on Easy, Normal or Hard. The closer guess knocks a heart off the other side.

Where the sizes come from

Sizes are typical values from encyclopedias and official sources such as NASA and the US National Park Service, rounded to keep them simple. Real things vary, so each size is a typical value, not an exact measurement.
