Nether portal coordinates calculator

Type where you are (or paste what F3 shows) and we'll tell you where the portal goes on the other side. That way the way there and the way back stay linked and nobody pops out of someone else's portal.

Where are you now?

Your coordinates

Or paste them as they are

The “Block” or “XYZ” line from F3, a /tp command or three plain numbers all work.

Build the portal in the Nether at

X
125
Y
64
Z
-300

From 0 0: 2,600 blocks walking through the Overworld, or 325 through the Nether.

The rule: divide by 8

Every block you walk in the Nether is worth 8 in the Overworld, along X and Z. So a portal in the Overworld at X 1000, Z -2400 has its partner in the Nether at X 125, Z -300. With negative numbers you round down: -1 divided by 8 is -1, not 0 (that's where doing it by hand goes wrong most often).

That makes the Nether a shortcut: to reach a base 4,000 blocks away, it's 500 through the Nether. On a server, a Nether hallway with portals to everyone's base is the most convenient setup for all.

Linking two portals, step by step

  1. Note down the coordinates of the Overworld portal (F3, the “Block” line).
  2. Convert them to the Nether here and travel to those coordinates through the Nether.
  3. Build the Nether portal there and light it. Now they're linked both ways.
  4. If the game had already created a stray portal nearby, break it so it doesn't send you off course.

Running the server? With /tp you get there without crossing lava, and if the Nether stutters when everyone explores it at once, pre-generate it with Chunky: the Chunky calculator tells you how much disk and time it takes.

Frequently asked questions

How do you convert coordinates to the Nether?

Divide X and Z by 8 and round down to the whole number below; Y stays the same. From the Nether to the Overworld, multiply X and Z by 8. It works the same in Java and Bedrock.

Why do I come out of a portal that isn't mine?

When you go through, the game looks for an existing portal near the calculated point and, if there isn't one, builds a new one. In Java it searches about 128 blocks around in the Overworld and about 16 in the Nether, so two Overworld portals close together can end up at the same Nether portal. Build it yourself at the coordinates you get here and each one will lead to its own.

Does the height (Y) have to match?

No: Y isn't scaled. Just don't put it on the bedrock roof in the Nether; if it has to sit at a different height, the link still works through X and Z.

Where do I see my coordinates?

In Java, press F3: the “Block” or “XYZ” line. In Bedrock, turn on “Show coordinates” in the world settings. You can paste that line into the calculator as it is.

Do you play in one person's world, only when they're on?

With a server, the world stays up even when the host isn't playing. At NapNodes the RAM in your plan is yours alone and each machine's load is public on the status page. Try it with a free 3 GB Minecraft server, no card and no end date.
