This page is 384,400 km tall — the distance from Earth to the Moon. Scroll down to travel upward, passing altitude milestones including Mount Everest (8,849 m), commercial aircraft cruising altitude (10,000 m), the Kármán line where space begins (100 km), the International Space Station (408 km), and all the way to the Moon. It puts the true scale of space into perspective like nothing else.
How to use: Scroll down with your mouse wheel, trackpad or finger. Your altitude is shown throughout the journey. There is no shortcut to the Moon — you have to earn it.
The World's Highest Webpage is a free interactive experience that is exactly 384,400 kilometres tall — the average distance from Earth to the Moon. Scroll down to travel upward through the atmosphere, past altitude milestones, through the vacuum of space and all the way to the Moon.
What you'll pass on the way up:
How to use it: Scroll down with your mouse wheel, trackpad or finger. Your current altitude is displayed throughout the page. The scale is intentional — the distance between each milestone is proportionally accurate, so you really feel how far away space is compared to where planes fly, and how incomprehensibly far away the Moon is compared to space itself.
Why does this exist? Most people have no intuitive sense of how big space really is. Graphs and numbers don't capture it the way scrolling does. This page makes you feel the scale physically — one scroll at a time.
