The hole "extends about 90 feet on the first floor -- wide enough to have allowed the vast majority of a 757 to enter the building, even considering the trajectory of the plane."

This is the FEMA/ASCE study:

It has some diagrams and good photos.

I don't recall seeing a picture of the exit holes in the WTC, although somebody (maybe Seatnineb) did post a video of some of the debris exiting the building. The holes were in the form of severed perimeter columns.
