Amity Arena is the area that the Huntsmen teams face off during the Vytal Festival and is considered the marvel from all 4 Kingdoms of Remnant. At the moment, let's first solve the area for the actual fighting arena and move on from there.

I had to find something to compare the arena with, and conveniently near the end of Volume 3, we get to see a large Nevermore break through the arena's forcefield. Using Pyrrha and Ruby as height references, I estimate the wingspan for the nevermore to be around 100 to 115 feet.

We also see when all the students are killing the nevermore we see it flat on the ground, with the wingspan being about the same as the smaller octagon on the arena.

After doing some measurements based on that small octagon to the main larger one, I can say that the larger octagon is about 5 times the size of the smaller one or about 500 feet in length.

Using an octagon calculator for the rest of the data, the total area for the actual arena alone is about 176,777 square feet or 16,423 square meters or 4 acres. In comparison, the largest stadium in the world, The May Day Stadium in North Korea, has a field around 22,500 square meters.

Using the arena, we can use it as a reference as I can assume that the largest point of the Stadium at the top is about 1500 feet in length.

After using the equation for finding the area of a circle, we find that the largest that the arena will be is around 164,000 square meters or 40 acres in area. The May Day Stadium in total is over 207,000 square meters or 51 acres.

Amity Arena is smaller than the largest stadium on Earth, but it depends In where in the stadium you are. The arena gets smaller from the bottom and so the area can depend on where you look at it. In terms of the actual arena to the stadium itself to the seating, where I estimate to have about 92,347 square meters or 23 acres, still shorter than the May Day Stadium.

While impressive, what is, even more, is the power of Dust tech and how it's applied to lift that island in the sky. (See Next Page.)

Revan4221: You are right that they aren't unkillable, just really tough. Never thought how chemical warfare would work on a Huntsman, could negate effects if Aura is strong enough. There is also the case how we never see how big the population in Remnant is, so we can't be sure and how it has been stated that there are new types of Grimm being discovered every day, so we would need to be expect anything and everything. I'll give you credit, most of your evidence is well backed up and I'm honestly impressed how seriously you take this for something that I do like a little hobby. Just take to note that stuff will be in inaccurate in some cases, but feel free to bash me for anything wrong!

Guest: That's an interesting theory along with the theory about Remnant having weaker gravity that I'll cover in the future.

Mr. Sandman: You are right in a sense. Planned to make Remnant Reality much sooner, but I had to rework the plot to better flow. I then got the idea to better research Remnant instead of just looking through the show. I'll make a story soon, but for now you have this!
