The Artemis II rocket is about 322 feet tall (about 98 meters) when fully stacked with the Orion spacecraft on top.

Quick Scoop

NASA’s Artemis II mission uses the Space Launch System, and multiple recent sources describe the full launch stack as standing 322 feet / 98 meters tall.

If you want, I can also break down how that height compares to Saturn V, the Statue of Liberty, or a 30-story building.
