Microscopic · #1004 biggest of 1,014
How big is a transistor (modern chip)?
3 nm
A transistor (modern chip) measures 3 nm. That's about 30 atoms lined up end to end.
By the numbers
- That's 3 nanometers (nm) — smaller than a wavelength of visible light.
- You'd need about 567 million of them stacked up to reach the height of an average adult.
- Roughly 30 atoms could line up across it.
- Out of all 1,014 things in this collection, it ranks #1004 by size.

Bars use a logarithmic scale so everything fits — real differences are even more extreme!
Fun fact
It's so small that about 333,333 of them would fit across a single millimeter.
