Q & A: Humans collected together

Q: If all humans could be put together how much space would the total be?

A: If you mean all humans on Earth physically packed together, the answer is surprisingly small! 🌎👨‍👩‍👧‍👦

With roughly 8.3 billion people alive today, and assuming an average human body has a volume of about 0.06–0.08 cubic metres, the total volume of all human bodies would be approximately:

500–660 million cubic metres.

To visualize that, imagine putting every person on Earth into one enormous cube. A cube containing about 600 million m³ would be roughly:

843 metres × 843 metres × 843 metres

So, incredibly, all 8.3 billion humans could theoretically fit inside a cube less than 1 kilometre on each side!

Another way to picture it: 🏙️

• Volume: ~0.6 km³
• Cube: ~0.84 km on each side
• Compared with a city: roughly the volume of a large downtown skyscraper district
• Compared with Earth: essentially microscopic

Of course, this assumes the bodies could be packed together with no meaningful gaps, which isn't physically realistic. If you allowed space between people, the required area and volume would become dramatically larger.

And there's an even crazier comparison: the total mass of humanity is only around 500 billion kilograms, or roughly 500 million tonnes. That's a lot of people—but on the scale of the Earth, it's almost nothing. 🌍
