How big is Times Square?

Answer 1

the space that one would consider to be strictly within Times Square is pretty small.

the area where you want to be is where Broadway and 7th Avenue intersect, and that occurs from 43rd Street to 46th Streets, so all you really need to do is: walk along the sides of Bway/7th Avenue between 43rd and 46th Streets, and you've basically seen 90% of all there is to see. it'll take you all of about 15 minutes.

of course, you can walk as far up Bway and 7th Avenue as you want, like to 50th Street, because those areas are always busy and lit up.
