I Too or Me Too? Which is correct?

“I Too” and “Me Too” are both correct but we use them in different contexts. We use “Me too” as a short answer when we agree with someone or have done the same thing. We use “I too” when we need to make a full sentence.

“Me too” is more common than “I too” because it is often redundant to repeat the action performed. “Me too” is slightly informal whereas “I too” can sound formal. 

It is also important to know that “me” is correct when “me” is the object of the sentence and “I” is correct when we need to use the subject of the sentence. 

Me too

We often use “me too” to say that you have had the same experience, belief, or opinion as someone else 

I was invited to the wedding.

Me too.

Notice that when we say “me too” we are using the object pronoun “me”. “Me” is the object of the verb “invited” because I received the invitation. You can read more about subject and object pronouns here

I too

We should use “I too” when we need to use the subject pronoun.

I love cats.

I too.

In the example, above we are doing the action (loving cats) and not receiving the action(in this case “the cats”). 

In modern English, this is not the way most people would respond. Most people would say “me too”.

I love cats.

Me too.

The only time people may use “I too” is when the experience or belief is lost in a longer speech and if you reply “me too”, it might be difficult to understand what you are agreeing on.

Example:

I like cars and motorbikes but I dislike the fact they use so much petrol and gasoline. We are ruining the environment. 

I too like cars and motorbikes. 

If we use “me too” in the above example, it might be confusing whether we agree with liking the cars and motorbikes or that cars and motorbikes are running the environment.

In reality, most people would use “I also” because “I too” sounds too formal/old-fashioned.

I like cars and motorbikes but I dislike the fact they use so much petrol and gasoline. We are ruining the environment. 

I also like cars and motorbikes.
