How big is a human egg cell?
100 µm
A human egg cell measures 100 µm. That's about 13 red blood cells lined up end to end.
By the numbers
- That's 100 micrometers (µm) — far too small to see with the naked eye.
- You'd need about 17,000 of them stacked up to reach the height of an average adult.
- Roughly 13 red blood cells could line up across it.
- Out of all 1,014 things in this collection, it ranks #980 by size.
