Loki’s Nidhogg dragon form is generally estimated to be hundreds of meters long , with some fan breakdowns pushing it into the kilometer range. The most cautious source-based estimate says it can be “estimated at hundreds of meters” when used by Loki.

What people are saying

  • Conservative estimate: a few hundred meters long.
  • Fandom speculation: around 3.5 km to 10 km+ depending on the scaling method used.
  • Why the range is so wide: there is no official fixed canon measurement yet, so fans are scaling from panel art and comparison characters.

Best simple answer

If you want the safest short answer: Loki’s Nidhogg form is probably at least several hundred meters, and possibly a few kilometers long.

TL;DR

The size is not officially locked in, but the most grounded estimate is hundreds of meters , while stronger fan estimates go as high as multiple kilometers.
