4x4 Tiles or larger

I was reading this unity blog post ( Experience the new Unity Terrain Demo scenes for HDRP and URP ) about the terrain demo using HDRP and URP. They said they created 4x4 tiles at 4000 units at scale.

But wouldn’t that be 1,000 tiles?

I’m creating an open world exploration game with a main island surrounded by smaller ones. I would like the main island to be roughly 3 square miles. But if I create that using 4x4 tiles, that’s a lot of tiles.

Would that be the preferred way? Or should I just use larger tiles?

I think it’s badly worded, maybe, but my interpretation is that they made 16 tiles total and each tile is 4000x4000.

In other words, the tiles are not 4x4 units, but rather the whole map is 4x4 tiles. I could be totally wrong, though.
