Nether Portal Guide
Understanding Portal Mechanics
In Minecraft, Nether portals create a connection between the Overworld and the Nether dimensions. The Nether acts as a fast-travel system, where 1 block in the Nether equals 8 blocks in the Overworld. This 8:1 ratio is key to calculating perfect portal links.
Portal Construction Guide
- Portals must be at least 4x5 blocks in size (including the obsidian frame)
- The minimum obsidian required is 10 blocks
- Portals can be up to 23x23 blocks in size
- Use a Flint and Steel or Fire Charge to activate the portal
- Ensure both portals are built at the exact calculated coordinates for reliable linking
Troubleshooting Portal Links
- If portals aren't linking correctly, verify both portals are built at the exact calculated coordinates
- Nether portals search for a valid portal within a 128 block radius in the Nether
- In the Overworld, portals search within a 1024 block radius
- Building portals above Y-128 in the Nether (on the roof) may cause linking issues
Safety Tips
When building a portal in the Nether, always bring:
- Enough obsidian for the portal frame
- A Flint and Steel or Fire Charge
- Building blocks for platforms and safety
- Fire resistance potions for emergencies
- A way to deal with hostile mobs
