Disneyland fireworks themselves are typically about 15 minutes long, and one Disneyland fireworks page lists the show duration as 15:00 while noting the show lights up the park at roughly 9:30 pm. A forum post about a Disneyland fireworks night also says the fireworks themselves are about 12 minutes , which suggests the exact runtime can vary by show or source.

Matterhorn angle

If you mean the view from or near the Matterhorn , that does not usually change the fireworks runtime; it just changes the viewing angle. The Matterhorn is one of the park’s well-known spots for watching the show, but the public sources I found do not give a separate “Matterhorn-only” fireworks length.

Quick answer

  • Typical Disneyland fireworks show length: about 12–15 minutes.
  • The location near the Matterhorn affects where you watch , not usually how long the show runs.

Note

Because the wording is a little unclear, I’m reading this as asking how long the Disneyland fireworks show lasts when viewed near the Matterhorn.
