The Twin Towers were each a little over 200 feet wide on each side of their square footprint, specifically about 207–209 feet (around 63–64 meters) per side.

Quick Scoop: How wide were the Twin Towers?

To picture it, each tower was essentially a giant square.

  • Each side: about 207–209 feet wide (roughly 63–64 meters).
  • That means the base was roughly 200 feet by 200 feet, forming a huge square footprint.
  • Each floor was about an acre in area, which matches that width and gives a sense of how massive a single level was.

In simple terms: walking along just one side of a tower at a normal pace could easily take close to a minute, which is why people often say they didn’t realize “how wide” they really were until they saw the numbers.

TL;DR:
Each Twin Tower was roughly 207–209 feet (about 63–64 m) wide on every side of its square base.
