There is no verified built-in command that finds an existing Nether portal by name. To find one you have already visited, save its coordinates; to find its likely counterpart in the other dimension, convert its X and Z coordinates using Minecraft’s 8:1 Nether scale, then search nearby. The game may link you to a different nearby portal, and the search behavior can vary by edition and version.
How to find a portal you have already visited
Coordinates are the most reliable way to return to a known portal. Record all three coordinates—X, Y, and Z—while standing at the portal, and keep track of which dimension they belong to. Minecraft’s coordinate guidance explains how to display them and use them to record locations.
- Java Edition: Press F3 to open the debug screen and read the coordinates.
- Bedrock Edition: Enable Show Coordinates in the world settings.
When returning, use the saved coordinates in the same dimension. If you do not have them, look for landmarks or retrace your route; a map is general navigation help, not a portal detector.
How to estimate where a portal connects
The Nether uses an 8:1 horizontal coordinate scale relative to the Overworld. Divide the Overworld portal’s X and Z coordinates by 8 to estimate its Nether-side location. To estimate the Overworld location from a Nether portal, multiply its X and Z by 8. Y is not scaled.
#1 Best Overall
- Write down the portal’s X, Y, and Z coordinates and note the dimension.
- Convert only X and Z using the 8:1 scale. For example, an Overworld portal at X=800, Z=-400 corresponds to an estimated Nether target of X=100, Z=-50.
- Travel to the estimated location in the other dimension and inspect the area for existing portals.
- Once you find the portal you want to use, record its coordinates so you can return to it.
The converted coordinates are a search target, not a guarantee of the exact exit location. Portal linking searches for an existing portal near the converted destination, so another portal in the search area may be chosen instead. The portal mechanics reference describes the coordinate scaling and search behavior: Nether portal linkage.
What maps can—and cannot—tell you
A map can help you navigate by showing your position, but the available map behavior differs by edition. Mojang’s cartography-table guide says Java maps automatically show the player with a pointer; in Bedrock, add a compass at a cartography table to make a locator map. Neither source describes maps as detecting or marking Nether portals, so coordinates remain the useful record for a known portal.

Portal search distance and linking behavior are not identical across every edition and version. The community-maintained mechanics reference notes a Java Nether-side search change in version 1.16.2. Mojang’s issue tracker also documents that the Java 1.16.2 changes had not been ported to Bedrock in the affected versions recorded there: MCPE-68258. Because these details can change, do not assume Java and Bedrock use identical search ranges; check guidance for your specific edition and version before relying on an exact distance.

Java and Bedrock at a glance
| Edition | Display coordinates | Map behavior | Portal search note |
|---|---|---|---|
| Java | Open the F3 debug screen. | Maps automatically show the player with a pointer. | The mechanics reference describes a Nether-side search change in Java 1.16.2; search behavior depends on version. |
| Bedrock | Turn on Show Coordinates in world settings. | Add a compass at a cartography table to create a locator map. | Mojang’s tracker documents that Java’s 1.16.2 changes had not been ported in the affected Bedrock versions it records; do not assume matching search ranges. |
