There are almost 100 trillion or 1014 cells in human body and on average the size of a typical cell is 10 micrometer. Human cells are eukaryotic cells and the size of a typical human cell is almost 10 times greater than the prokaryotic cell. On the other hand bacteria are unicellular prokaryotic organisms and there are 40 million bacterial cells in one gram of soil. The size of a typical bacterial cell is  0.5–5.0 micrometer.

This shows that human cells are bigger than the bacterial cells almost ten times. There can be even variations in the sizes of bacterial cells and the smallest bacterial cell is about 0.3 micrometer in the genera Mycoplasma.
