For those who visited the Pre-9/11 twin towers themselves. What was the size of the buildings like?

The only reason I ask is I never myself got a chance to visit New York City before in the past so far during my 38 years of life on this world we call Planet Earth and as such that is one of my biggest regrets as the original World Trade Center towers got demolished in the September 11th, 2001 terrorist attacks before that was possible.

So for you guys that did get to see the twin towers physically in person prior to 9/11. What was the size of those buildings like pictured above when you got do so, and why?
