How long is it? VS How long does it take?

First off, VS means VERSUS and is often used in boxing. For example:

Mike Tyson VS Evander Holyfield

So today I will talk about the differences between these two sentences.

HOW LONG DOES IT TAKE?

This is often used to talk about flights, boat trips, train trips, etc. It is short for:

How long does it take (to get there)?

or

How long does it take (to get to ___________ )?

It has no positive or negative connotations or nuances. It is a simple request for information.

HOW LONG IS IT?

When talking about time, this has a NEGATIVE connotation. It means that I have something else to do or I don't really want to do this so I am hoping it will finish quickly.

If you are asking about a tour when traveling and say "How long is it?" the guide will get the feeling you want it to be a short tour.

You can also use this to talk about movies or music albums where it isn't negative just a bit strange. It is not a normal question when talking about movies or CDs...

Be careful!

A: Would you like to see a movie?

B: Sure. Which one?

A: How about Titanic?

B: Uuum, how long is it?

A: ???

In this conversation, person A will get the feeling you don't really want to see Titanic!

Have a good weekend,
