Chromosome 1 is the longest human chromosome at 245,203,898 base pairs (bp) according to the published sequence[1]. And the distance between base pairs along the sugar-phosphate backbone of DNA is about 0.33 nanometers (nm). Thus the total length

 

So the largest human chromosome is almost almost ten centimeters in length!
