Calculators for game mechanics. The Nether Portal Calculator converts Minecraft coordinates between the Overworld and the Nether so your portals link up.

How Nether Coordinates Work
In Minecraft, one block in the Nether matches eight blocks in the Overworld on the X and Z axes. To find where to build the Nether side of a portal, divide your Overworld X and Z by 8. To go the other way, multiply by 8. The Y coordinate (height) is not scaled. An Overworld portal at X 800, Z −240 matches a Nether portal at X 100, Z −30.
Build the second portal as close to the converted point as you can. The game links a portal to the nearest one it finds nearby, so a portal far from the right spot can connect to the wrong one.
Frequently Asked Questions
What is the Nether ratio in Minecraft?
1 : 8. Each block you travel in the Nether covers eight blocks in the Overworld, which is why players use the Nether for fast travel.
Does the Y coordinate change between the Overworld and the Nether?
No. Only X and Z are divided or multiplied by 8. Keep the portal at a height you can reach on both sides.
Are the gaming calculators free?
