Nether Portal Calculator — Minecraft Coordinate Converter
Find the exact Nether coordinates where you need to build a portal so it links back to your Overworld location. Enter your Overworld X and Z and the calculator divides by 8 — the Nether scale factor in Minecraft Java and Bedrock editions.

Nether X coordinate
1,600 ÷ 8 = 200The Nether is scaled 1:8 — every block here equals 8 Overworld blocks.
How does this calculator work?
Divide your Overworld X and Z by 8 to get the Nether coordinates where you must build your portal: Nether X = Overworld X ÷ 8, Nether Z = Overworld Z ÷ 8. Build within ~1 chunk (16 blocks) of those coordinates to guarantee the portals link. Y is not scaled — pick any safe height.
Formula
How this is calculated
In Minecraft, the Nether dimension is scaled 1:8 relative to the Overworld — every block you travel in the Nether corresponds to 8 blocks in the Overworld. When the game tries to link two portals, it converts each portal's coordinates to the other dimension using this factor. To guarantee that a Nether portal connects to a specific Overworld portal, you must build the Nether-side portal within one chunk (16 blocks) of the scaled coordinate — rounding the result to the nearest whole number is usually fine.
This conversion applies to the X and Z axes only. The Y (height) axis is not scaled; you choose a convenient Y level in the Nether independently, typically between Y=64 and Y=100 to stay above the lava sea and below the ceiling. Press F3 in-game (Java Edition) or tap the coordinates display (Bedrock Edition) to read your exact X, Y, Z position.
If you already know the Nether coordinates and want to find the linked Overworld position, simply multiply by 8 instead. The formula works identically for negative coordinates (west or south quadrants of the world).
Frequently asked questions
The Nether world is generated at 1/8th the scale of the Overworld. One block of horizontal travel in the Nether moves your "linked" Overworld position by 8 blocks, making the Nether the fastest way to cover long Overworld distances.
The Y axis is not scaled. A practical Y level is between 64 and 100 — high enough to avoid the lava ocean (Y=31) and low enough to avoid the Nether roof (Y=128 in Bedrock, inaccessible in Java). Build at a Y that gives you safe access.
The game searches for an existing portal within 128 blocks in the Nether (16 blocks in older versions). If another portal is closer to the calculated coordinates, the game will link to that one instead. Remove or relocate competing portals to force the correct link.
