It just means "more than one block, but less than three". If someone said something was "two blocks away", I would expect to have to cross two streets to get there.

What does it mean 1 block away?

27 Sep 2019. A block is the distance on a street between one cross street and the next cross street. If you are 'three blocks away' from something, you are three of these (in the image) away.

How far is a block away?

A block is not really defined by distance, but rather is defined by the distance between cross streets, which could be 50 feet or 200 feet, depending on the place. Most blocks in cities tend to be between 200 – 300 feet apart, so the distance between 2 blocks would be roughly 400 – 600 feet.
