DNA'S MOLECULAR IS VERY SMALL AND it's width is 20 angstrom.but dna is made by many helical pairs. a helical pairs's length is 34 angstrom.

One 360 degree turn of DNA measures 34 angstroms in the direction of the axis. The width of the molecule is 20 angstroms, to the nearest angstrom. These lengths, 34:20, are in the ratio of the golden mean, within thelimits of the accuracy of the measurements. Each DNA strand contains periodically recurring phosphate and sugar subunits. There are 10 such phosphate-sugar groups in each full 360 degree revolution of the DNA spiral. Thus the amount of rotation of each of these subunits around the DNA cylinder is 360 degrees divided by 10, or 36 degrees. This is exactly half the pentagon rotation, showing a close relation of the DNA sub-unit to the golden mean

A natural helix of DNA is 20 angstroms wide. Stanford University scientists have created an expanded version, called xDNA, which is 22.4 angstroms across.
The persistence length of DNA is 50nm.
The average length per base pair in B-DNA is 3.4 angstroms (an angstrom equals ten to the minus ten meters).
The length per base pair of B form DNA is 3.4 angstroms, therefore the total stem length would be 30.6 angstroms.

About 20 angstroms wide, and 10,200,000,000 angstroms long
edit: we are talking human DNA, right?

well i don't know about the exact width as it is in a double helix form ,but it is around 2-2.5nm or
20-25Angstrom.
The length of a DNA is,3.4nm or 34Angstrom
