What is the size of the columnar epithelial cells ????

@ joe 
the size of columner epithellium is 20 micrometer . 
squamous epithellium – 40-60 micrometer 
cuboidal epithellium – 14-15 micrometer . 
and just remember that their height are at least 4 times of their width . 
ALL THE BEST ..

The columnar epithelial cells are 20 μm tall and 10 μm wide(given size is approximate value).

 

Hope you got the answer.

 

Thanks.
