A nucleus is generally 10 to 20 micrometers in diameter.  However, in 
humans, nuclei are only 6 micrometers in diameter on average.

Mitochondria are approximately 1 micrometer in length. 

Chloroplasts can be up to 10 micrometers long and 0.5 to 2 micrometers 
thick.  However, they do vary in shape and size in different types of 
cells.
