Detailed explanation-1: -Most common bacteria are about 1 to 2 microns in diameter and 5 to 10 microns long. A micron is one millionth of a meter, or 1/10, 000th of a centimeter. The human eye is amazing. Still, unaided, the smallest objects our eyes can see are about 100 microns long.
Detailed explanation-2: -From several images analyzed and more than 200 bacterial cells computed, the average dimensions obtained were: length 3.71 ± 0.18 µm and wide 1.73 ± 0.04 µm.
Detailed explanation-3: -Bacteria generally range from 0.3 to 5 microns (one micrometer, or 10-6 meters), with E. coli a respectable 2 microns in length, and typically approaching 1 micron in width. Most eukaryotic cells would loom over a bacterium, being at least 10 to 20 times wider.
Detailed explanation-4: -The size of a microbe is usually measured in micrometers, or one millionth of a meter.
