Overworld Nether
Nether coordinate (÷8)
12 64 -32
X and Z are divided by 8 (rounded down to the block). Y stays the same.
Nether Overworld
Overworld coordinate (×8)
96 64 -248
X and Z are multiplied by 8. Y stays the same.
Portal pairing helper
Using your Overworld portal at 100 64 -250, build the paired Nether portal here so the two link reliably:
Build the Nether portal at
12 64 -32
Nether search radius
128 blocks
The game looks this far (Nether scale) for an existing portal before making a new one — build within a few blocks of the spot above.
Keep separate pairs apart by
≥ 1,024 blocks
Two Overworld portals closer than this (on X or Z) risk sharing one Nether portal.
Distance & Nether shortcut
Overworld point A
Overworld point B
Overworld distance
1,442blocks
Same trip via the Nether
180blocks
Digging a Nether highway between these points is 8× shorter — you only walk 180 blocks instead of 1,442.
