The largest webpage is 9 quadrillion pixels wide by 9 quadrillion pixels tall.  If you could see it laid out without scroll buttons, it would be 17 billion times the surface are of the Earth.

And if you were to repeatedly click (or hold down) the right arrow on the scroll bar, thus moving the image from the left hand side to the right hand side, it would take you half a million years to reach the end.

That’s one big page, and it’s right here.  (No, it doesn’t take long too load at all….)
