Question: How do I compute the length or size of a list or array?

I spent the last 2 hours searching in the Help commands for the command that returns the length or size of a given ordered array or list.

e.g. I have Thing:=[3,7,6,5]:

I want the function that returns the value 4 for the size of Thing.

I am really surprised that such an operation is so difficult and hard to compute that it is never in any of the Help menus.
