Nether Portal Calculator (Java & Bedrock)
Divide your Overworld X and Z by 8 to get Nether coordinates, and multiply Nether X and Z by 8 to go back. Overworld 1000, -480 becomes Nether 125, -60.

How to use it
- Press F3 (Java) or turn on Show Coordinates (Bedrock) and note your X, Y and Z.
- Pick which dimension you are in, then type the numbers into the calculator.
- Go through your portal and travel to the X and Z shown in the green box.
- Build and light a new portal there. The two portals will now link to each other.
- Use Share link to send the exact coordinates to friends on your server.
How it works
One block of travel in the Nether equals 8 blocks in the Overworld, on the X and Z axes only. The calculator divides by 8 and rounds down, the same way the game maps a position to the other dimension. Height (Y) is not scaled.
Questions
Does the Y coordinate change in the Nether?
No. Only X and Z are divided by 8. Build your portal at a similar height if you can, but the Y value itself is not scaled.
Why did my portal take me to the wrong portal?
Portals link to the closest existing portal near the matching coordinates. If two portals are close together, the game may pick the other one. Build the second portal exactly at the calculated X and Z to link them reliably.
Why is Nether travel faster?
Because 1 block in the Nether equals 8 blocks in the Overworld, walking 100 blocks in the Nether moves you 800 blocks in the Overworld.
