You are shorter than he or him?

Here is a website with the rules of comparison.

"English Grammar"
Comparision using comparative adjectives and adverbs
To say that people, things etc are unequal in a particular way, we can use comparative adjectives/adverbs.

She is older than me.
Tom is taller than his brothers.
Iron is more useful than any other metal.
He is cleverer than her.

In an informal style, object pronouns are used after than. In a more formal style, subject pronouns are used usually with verbs.

He is cleverer than she is.
He earns more than I do.

I think this site can help people make their minds clear and find the correct answer about which one should be used in which case.

By the way, being an ignorant in using those grammatical terms such as "object pronouns" and "subject pronouns" I ask for you to show their examples while using them please.

As a last two remarks, I need to tell that "you are shorter than he" doesn't seem correct in both formal and daily usage for me as well.

Subject pronouns are the ones that are subjects in the sentences.(nominative case)
e.g. He is smart;you are clever, they are wonderful.

Object pronouns are the ones that are objects in the sentence.
e.g.Maria likes him; Rodger wrote it; people love them.

Thank you very much for your taking time on making these explanations.

I am bound to admit that I would rather you began your message with at least a formal greeting.

Assuredly, "You are shorter than he is" and "You are shorter than him" are both standard and worthy of being accepted but the very difference lies between formality and informality. We encounter the former in formal speeches, written papers and presentations, though; the later is admissible in informal speeches and so forth. Given the fact that, we can see both of them in grammar books like advanced grammar in used by Martin Hewings, a practical English grammar by A.J. Thomson and A. V. Martinet and practical English usage by Michael Swan. The authors didn't differentiate them and they all accepted that both are free from error or fault.
