Microscopic · #993 biggest of 1,014
How big is a chloroplast?
5 µm
A chloroplast measures 5 µm. That's about 50 viruses lined up end to end.
By the numbers
- That's 5 micrometers (µm) — far too small to see with the naked eye.
- You'd need about 340,000 of them stacked up to reach the height of an average adult.
- Roughly 50 viruses could line up across it.
- Out of all 1,014 things in this collection, it ranks #993 by size.

Bars use a logarithmic scale so everything fits — real differences are even more extreme!
Fun fact
It's so small that about 200 of them would fit across a single millimeter.
