what size in acres are the chicago o'hare terminals

Chicago O’Hare’s entire airport complex is reported at over 7,200 acres, while newer airport references also list it at about 7,627 acres; the passenger terminals themselves are part of that total, but the airport sources I found do not break out terminal acreage separately.

What that means

• O’Hare has four passenger terminals: 1, 2, 3, and 5.

• The acreage figures refer to the whole airport property, not just the terminals.

• So if you mean “how big are the terminals combined,” the public sources here don’t give a clean terminal-only acre total.

Practical answer

For a quick estimate, it’s safest to say: Chicago O’Hare is about 7,200 to 7,627 acres total , with the terminals occupying only a portion of that land.
