This question actually has many different answers as there are many types of cells. A cell, no matter what its composition, will be invisible to the human eye on its own. A skin cell is about 1/1000 the size of a grain of salt- too small for us to even really comprehend. A red blood cell is about 1/10 the size of a skin cell. Small enough that thousands of these cells could fit on the tip of a needle. So, cells are small, but vary depending on their composition. Check out the link below for an interesting perspective on how small cells, atoms and other particles that compose the matter around us really are.
