Common questions
World Border Calculator FAQ
Is world-border size a radius?
No. The command size is the full side length or diameter, so the half-size reaches from the centre to an edge.
How does the calculator show an outside position?
It labels the position outside and reports the absolute number of blocks beyond the nearest boundary.
