The head of a typical pin has a diameter of about 1 millimeter, which translates to an area of approximately 0.785 square millimeters. Since a single E. coli bacterium is about 2 micrometers in length and 1 micrometer in width, roughly 10,000 E. coli cells could fit on the head of a pin, depending on their arrangement. This highlights the incredible microscopic scale of bacteria compared to everyday objects.
