How about vs. what about

Are “how about” and “what about” used exactly the same ways?


Most of the time, certainly.

I’m trying to think of an example where they aren’t (because I’m sure a few exist) but off the top of my head I can’t come up with one.


Both expressions are used when you offer a suggestion. Broadly speaking ‘How about doing something?’ is when you put forward an idea as in: How about travelling there by bus?, which is not a very original or positive suggestion. 'What about spending the summer in Canada? suggests an original or a fresh idea that would provoke quite a bit of interest.
