Sense of Scale

Tap any object to pin it as a ghost outline, then zoom to see how it compares with everything else. Press 🎯 Hunt to race the clock: find objects from size clues.

Every object is drawn at its true size compared with its neighbours. The width of the bar above shows the distance written beneath it.

Sizes are widely published values, rounded. For living things and buildings they are typical heights or lengths; for stars, galaxies and the universe they are diameters, some known only roughly.
