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)

Build plan
Nether hub at (50, 64, -20) · total tunnel: 140 blocks (covers 1.1 km of overworld)
- Home 70 blocks of tunnel (50 W + 20 S) — saves ~560 blocks of overworld travel
- Village 70 blocks of tunnel (50 E + 20 N) — saves ~560 blocks of overworld travel
