How to Make a Nether Portal in Minecraft

You can link Nether Portals too

If you want to visit the fiery underworld, you need to know how to make a Nether Portal in Minecraft. Here's all the information you need, including the correct Nether Portal dimensions and how to build your portal.

Instructions in this article apply to Minecraft for all platforms including Windows, PS4, and Xbox One.

What Do You Need to Make a Nether Portal?

Nether Portals offer a gateway to the Nether, Minecraft's underworld. There are a few ways to construct Nether Portals, but they always require the same materials:

  • At least 14 obsidian blocks
  • An item that can create fire, such as lava, a fire charge, or flint and steel

The minimum dimensions for a Nether Portal are four obsidian wide and five obsidian high (for a total of 14 obsidian blocks). If you'd like, you can construct even larger frames and build adjacent Nether Portals that share sides.

Mobs can also travel through portals, so they can follow you from the overworld to the Nether and vice-versa.

Follow these steps to construct a portal to the Nether:

  1. Add obsidian and your combustible block (fire charge, flint and steel, etc.) to your hot bar.

When you arrive, the portal you built will follow you. To return to the overworld, reenter the portal.

The Nether randomly generates just like the overworld; however, there is only one Nether per world, so each portal you make will link to the same Nether.

How Much Obsidian You Need and Where to Get It

You'll need at least 14 obsidian per Nether portal, so you should collect as much as possible. To mine obsidian in Minecraft:

  1. Make a crafting table using four wood planks. Any type of wood will do (Warped Planks, Crimson Planks, etc.).

How to Deactivate Portals

There are a few things that can deactivate Nether Portals:

  • Explosive blasts
  • Water
  • Destroying the obsidian frame with a pickaxe

Although the obsidian frame can withstand explosions, the portal itself cannot. Nether Portals can be reactivated the same way you originally activated them.

To protect your portals, shelter them with cobblestone or other blast-resistant stone bricks.

How to Link Nether Portals

Anytime you make a new Nether Portal, a link between the Nether and the overworld is created. Portals work both ways, so you can go back and forth. Once you're in the Nether, you can place portals in strategic locations to create shortcuts to the overworld.

The Nether is smaller than the overworld by a ratio of 8:1 on the X-axis. In other words, if you move one block to the left or right on the map while in the Nether, you will have moved the equivalent of eight blocks in the overworld. The Y-axis ratio is 1:1, so this doesn't apply when moving up or down on the map.

You can create as many portals as you like; however, if you place multiple portals in close proximity, they will lead to the same spot.
