Nether Coordinate Calculator
Instantly convert between Overworld and Nether coordinates. Type in either side — the other updates live.
Linking Portals
Divide your Overworld X and Z by 8, then build your Nether portal at exactly those coordinates for a guaranteed direct link.
Chunk Alignment
Keep portals well inside a single chunk (16×16 blocks). Portals near chunk borders can link to unexpected locations.
Fast Travel
1 block in the Nether = 8 blocks in the Overworld. A 10,000-block Overworld trip shrinks to just 1,250 blocks in the Nether.
Frequently Asked Questions
What is the exact ratio between dimensions?
Exactly 8:1. Every block traveled in the Nether equals 8 blocks in the Overworld — both Java and Bedrock editions use this same ratio.
Why do my portals sometimes link incorrectly?
Two Overworld portals that are too close may share the same Nether portal. Fix it by manually building a second Nether portal at the calculated coordinates for your second Overworld portal.
Does the Y coordinate matter for linking?
Primarily no — the game matches portals by X and Z. Y can matter if two portals share the same X/Z but differ in height; the nearest one wins.
Does this work for Bedrock Edition?
Yes. The 8:1 coordinate ratio is identical in Bedrock Edition. These calculations apply regardless of platform.
