Nether Coordinate Calculator
Convert coordinates between the Overworld and the Nether
Free Minecraft Nether portal coordinate calculator. Convert Overworld coordinates to Nether coordinates and back using the 1:8 ratio. Avoid portal mislinks with built-in safety tips.
Read the transcript
The Nether coordinate calculator converts a point from one dimension to the other.
The two worlds are tied by a one-to-eight ratio: one block in the Nether equals eight blocks in the Overworld. So to make a portal come out where you actually want it, the coordinates have to be divided or multiplied.
Type your coordinates and the calculator immediately shows the matching pair for the other dimension along with a ready teleport command you can copy with one button.
Next to it are the notes on what usually goes wrong. Portals link to the wrong place if you build them closer than sixteen blocks apart: the game ties the new portal to an existing one. For automatic generation the height is limited to the range from seventy to one hundred and eighteen. And the world border in the Nether is eight times smaller, so you cannot walk past the edge through it.
How does it work?
- Find your Overworld coordinates — Press F3 (Java) or enable coordinates in settings (Bedrock) to see your X, Y, Z position.
- Divide X and Z by 8 — The Nether is 8× more compact horizontally. Y stays the same — vertical scaling does not apply.
- Build the portal at the result — Build your Nether portal at the calculated coordinates so portals link correctly between dimensions.
Frequently asked questions
Why is the ratio 1:8?
Mojang designed the Nether as a fast-travel dimension. One block of horizontal travel in the Nether equals 8 blocks in the Overworld, making it ideal for long-distance routes via Nether highways.
Does the Y coordinate change?
No. Y is preserved when you teleport between dimensions. Only X and Z are scaled by the 1:8 ratio.
What is a portal mislink?
A mislink is when a portal leads you to an existing portal you did not mean to use. When you step through, Java Edition converts your position (÷8 into the Nether, ×8 back) and sends you to the closest existing portal near that point — it searches up to 16 blocks around it in the Nether and up to 128 blocks in the Overworld. Only if none is found does it build a new portal.
How do I fix a portal mislink?
Build the destination portal yourself at the exact coordinates this calculator gives, so it is the closest portal to the arrival point, then break the unwanted portal the game generated. In Java Edition, portals that must lead to different places should stand more than 16 blocks apart in the Nether.
What is the build height in the Nether?
In Java Edition the build limit is 256, with a bedrock ceiling at Y=123–127. In Bedrock Edition the limit is 128. You cannot normally get above the ceiling in Java; players reach the roof through unintended tricks such as ender-pearling through the bedrock, and can then build up to 128 blocks higher.
Is the calculation rounded?
Minecraft uses floor division for portal coordinate matching. Our calculator shows both the exact value and the integer the game actually uses for portal placement.
