The 400-pound Queens pedestrian who crashed through an Upper East Side sidewalk said yesterday that a thinner woman might have died from that fall.

“Thank God, they said that my size was the only thing that saved me,” Ulanda Williams, 32, told The Post as she was discharged from NewYork-Presbyterian Hospital.

City Department of Buildings inspectors found that a 4-by-6-foot section of sidewalk had collapsed into a vault cellar in front of the building.

“I was standing there approximately 10 seconds and when that occurred, I just fell right through,” said Williams, who stands about 6-foot-5.

The FDNY had to use a crane and cargo net to get her out.
