The reason Nether travel is worth building for is the ratio: one block walked in the Nether covers eight in the Overworld. A 40-block tunnel replaces a 320-block Overworld journey. A hub is just that advantage, organised.

Plan in Nether blocks, not Overworld blocks

The two spacing constraints are:

• Overworld portals more than 128 blocks apart
• Nether portals more than 16 blocks apart

These describe the same distance seen from each side of the ratio, so satisfying the Nether one automatically satisfies the Overworld one. Since 16 is the tighter number to work with, plan there and stop worrying about the Overworld side.

A worked hub:

20 ≥ 16 and 160 ≥ 128. Both clear, and only one number had to be checked.

Where the derivation comes from is set out in how far apart do nether portals need to be.

Give yourself margin

Sitting exactly on 16 is not a plan. Terrain forces portals a few blocks off target, and the radius is measured from the scaled coordinate rather than from your portal, so small errors eat the margin from both ends.

Space hub portals 24–32 Nether blocks apart. That is 192–256 Overworld blocks between destinations, still tight enough for a compact hub, with room to shift a portal when you hit a lava lake.

Building order that avoids rework

1. Pick the Overworld destinations first. Real places you actually travel between — base, farms, villages, mining outposts.
2. Convert each to Nether coordinates with the nether portal calculator. Write the list down.
3. Check the Nether gaps. If two destinations land within 16 Nether blocks of each other, they cannot have separate hub portals — either merge them into one stop, or move an Overworld portal further away.
4. Build the Nether portals at those exact coordinates, one at a time, testing each round trip before starting the next. The linking guide has the per-portal method.
5. Connect them with tunnels afterwards. Tunnels are cosmetic; the links are what matter, and digging before testing means digging twice.

Testing each portal as you go is the single habit that saves the most time. Building six portals and then discovering two of them cross-link means unpicking a hub you have already tunnelled through.

What the ratio actually saves

At a walking pace, the same journey:

The saving grows linearly with distance, which is why hubs pay off for far-flung bases and are barely worth it for two locations 200 blocks apart — that trip is 25 Nether blocks, less than the tunnel you would dig to reach it.

A few things that will bite

Y is never scaled. A hub at Y=70 serving an Overworld base at Y=12 still works, but match heights where you can — it keeps arrival points predictable.

Terrain overrides your plan. If the exact scaled coordinate is inside bedrock or over a lava ocean, you will have to shift. Shift, then re-check the gap to neighbouring portals rather than assuming the margin absorbed it.

Portals in the Nether are exposed. Anything that wanders near a portal can follow you through. Enclose hub portals rather than leaving them open to the wastes.

Adding a destination later can break an existing pair. A new Overworld portal within 128 blocks of an old one will compete for the same Nether portal. Check the gap before building, not after.
