Nether Portal Linker & Network Mapper

Plan a nether hub: enter your overworld bases, get exact nether portal coordinates (x ÷ 8, z ÷ 8), catch portals that would cross-link, and map the hub tunnels. 1 nether block = 8 overworld blocks.

Overworld bases

Coordinates of each overworld portal. Z runs north (−) to south (+).

X
Y
Z

Nether portal: (0, 64, 0)

X
Y
Z

Nether portal: (100, 64, -40)

Hub settings

Y is not scaled between dimensions, so keep the nether side at roughly the same height as the overworld portal. Most players pick one hub Y and build every nether-side portal at it.

Hub position

Hub at (50, 64, -20) in the Nether.

Coordinate converter

Nether: (0, 0) (Y unchanged)
