How It Works

Overworld to Nether

Nether X = Overworld X ÷ 8

Nether Y = Overworld Y

Nether Z = Overworld Z ÷ 8

Nether to Overworld

Overworld X = Nether X × 8

Overworld Y = Nether Y

Overworld Z = Nether Z × 8

Portal Alignment Offset

How It Works

Travel Ratio (8:1)

Every 1 block traveled in the Nether equals 8 blocks in the Overworld. This applies only to the X and Z axes. The Y axis remains unchanged between dimensions.

Portal Linking

When you enter a portal, the game searches for the nearest existing portal within 128 blocks in the destination dimension. If none is found, a new portal is created at the calculated coordinates.

Pro Tip

For perfect portal linking, build your Nether portal at the exact coordinates shown by the calculator.
