Distance measurement

Is there any way to measure long distances? I know about landscape tool, but it is suitable only for small distances. Or maybe someone can tell me world size and radius of the church.

Its 200 tiles of full light in every directions from church, so 200x200. The full darkness start with after next like a 100 tiles so area of Church is like a 300x300
