Nether Portal Calculator

Introduction

The Nether Portal Calculator helps you build and manage portals in Minecraft. When you travel through a Nether portal, every 1 block in the Nether equals 8 blocks in the Overworld. This makes Nether travel much faster for long trips. But portal math can be tricky, and placing portals wrong can cause them to link to the wrong spot.

This tool makes portal building easy. Type in your Overworld coordinates to see where your portal will appear in the Nether. Or type Nether coordinates to find the matching Overworld spot. You can also check if new portals will work right or if they're too close to old ones. The calculator shows you how many obsidian blocks you need for different portal sizes and helps you plan a whole network of portals. Use it to save time on long trips and avoid portal linking problems. For managing your Minecraft inventory more efficiently, try our Minecraft Stack Calculator to figure out how many stacks your items will take up.

How to use our Nether Portal Calculator

Enter your Minecraft coordinates to convert between Overworld and Nether dimensions. The calculator will show you where to build matching portals.

Overworld X, Y, Z: Type the X, Y, and Z numbers from your Overworld location to see where to build in the Nether.

Nether X, Y, Z: Type the X, Y, and Z numbers from your Nether location to see where to build in the Overworld.

Existing Portal coordinates: Enter the location of a portal you already built to check if new portals will connect properly.

New Portal coordinates: Enter where you want to build a new portal to see if it will work with existing ones.

From and To coordinates: Enter two Overworld locations to see how much faster you can travel using the Nether.

Portal Size selector: Click a size option to see how many obsidian blocks you need for different portal sizes.

Portal Name and Network coordinates: Type a name and location for each portal to manage multiple portals in your world.

Corner blocks checkbox: Check this box if you want to add optional corner blocks to your portal frame.

Understanding Nether Portals in Minecraft

Nether portals are magical gateways in Minecraft that connect two dimensions: the Overworld (where you normally play) and the Nether (a dangerous, fiery dimension). These purple, glowing doorways are one of the most important structures you can build in the game.

How Nether Portals Work

When you step through a Nether portal, the game uses special math to figure out where you should appear. Every block you travel in the Nether equals eight blocks in the Overworld. This means if you walk 100 blocks in the Nether, you've actually traveled 800 blocks in Overworld distance. This makes the Nether perfect for fast travel across your Minecraft world.

Building Your Portal

To build a portal, you need obsidian blocks and flint and steel. The smallest portal needs 10 obsidian blocks arranged in a rectangle that's 4 blocks wide and 5 blocks tall. You can make bigger portals too - up to 23 blocks wide and 23 blocks tall! Once built, light the inside with flint and steel to activate the purple gateway.

Portal Linking Rules

Portals can sometimes connect to the wrong place if they're too close together. In the Overworld, portals should be at least 128 blocks apart to work properly. If they're closer, they might link to the same portal in the Nether, causing confusion. The game always looks for the

Frequently Asked Questions

What happens if I build two portals too close together?

When two portals are closer than 128 blocks in the Overworld, they might link to the same portal in the Nether. This means both portals take you to the same place instead of different spots. To fix this, move your portals at least 128 blocks apart.

Can I build a portal sideways or upside down?

No, you cannot build portals sideways or upside down in Minecraft. Portals must stand upright like a door. The frame must be vertical with the opening facing north-south or east-west.

What is the fastest way to get obsidian?

The fastest way to get obsidian is to pour water on lava source blocks. Find a lava pool, place water next to it, and the lava turns into obsidian. You need a diamond or netherite pickaxe to mine obsidian blocks.

Why does my portal take me to the wrong place?

Your portal might connect to the wrong spot because the game found a closer portal within 128 blocks. To fix this, break the wrong portal or build your new portal exactly where the calculator tells you.

Can animals and items go through portals?

Yes, animals, mobs, and dropped items can go through portals. Push animals into the portal or throw items through. They will appear on the other side after a few seconds.

Do I need corner blocks for my portal?

No, corner blocks are not needed for portals to work. You can save 4 obsidian blocks by leaving the corners empty. The portal will still light and work perfectly without them.

How high can I build a portal?

You can build portals at any height in both dimensions. In the Overworld, you can build from Y=-64 to Y=320. In the Nether, you can build from Y=0 to Y=256. The calculator adjusts these limits for you.

What size portal is best for farms?

The standard 4x5 portal works best for most farms. It uses the least obsidian and fits in small spaces. Bigger portals don't transport items or mobs any faster, so save your obsidian.
