Minecraft Nether Portal Calculator - Coordinate Converter
Free online calculator to convert Overworld coordinates to Nether coordinates. Plan nether portals, calculate obsidian requirements, and travel distances.
Overworld
Enter Overworld coordinates
Nether
Result
1 block in the Nether = 8 blocks in the Overworld
The Y coordinate is not scaled between dimensions, but affects portal linking distance.
How Nether Portal Coordinates Work
The Nether operates at 1/8 the scale of the Overworld on X and Z axes. This means travelling 1 block in the Nether is equivalent to 8 blocks in the Overworld, making it ideal for fast travel. Use this calculator to find the exact coordinates where you should build portals in each dimension to link them correctly.
Portal Linking Rules
When you enter a portal, the game searches for the nearest existing portal within range in the destination dimension. In Java Edition, the search radius is 128 blocks in the Nether and 1024 blocks in the Overworld. If no portal is found, a new one is created.
Tips for Perfect Portal Linking
- 1.Build your Nether-side portal at the exact calculated coordinates for reliable two-way linking.
- 2.Portals should be at least 1,024 blocks apart in the Overworld (128 in the Nether) to avoid cross-linking.
- 3.The Y coordinate matters for linking distance — try to match Y levels when possible.
- 4.Use F3 in-game to view your exact coordinates before entering them here.
