About DNA Length

DNA (deoxyribonucleic acid) is the molecule that contains the genetic code of all living organisms. In humans, DNA is tightly packed into chromosomes within the nucleus of each cell.

If you were to unravel and stretch out all the DNA from a single human cell, it would be about 2 meters (6.5 feet) long. Considering that the average adult human body contains approximately 30-40 trillion cells, the total length of DNA in your body is truly astronomical!

How is this calculated?

This calculator estimates the number of cells in your body based on your weight and height, then multiplies by the average DNA length per cell (approximately 2 meters) to calculate the total length.

Fascinating DNA Facts
  • 🧬DNA is incredibly thin - about 2.5 nanometers in diameter (2.5 billionths of a meter).
  • 👥Humans share about 99.9% of their DNA with each other.
  • 🍌We share about 60% of our DNA with bananas and 96% with chimpanzees.
