How do I resize terrain?

Well the title says it all
please help me I can’t find a way and I don’t want to put two terrains next to each other?

Thanks Jakob

In the Terrain component, go to Settings (right-most button, cog symbol), and under Resolution, set the Terrain Width/Length in world units. You might also want to change the Heightmap Resolution (increase it for larger maps), but that could get a bit complicated (it must be a power of 2 plus 1).
