Quick Reference
Common conversions (Overworld → Nether)How to convert Overworld and Nether coordinates
Pick the direction
Overworld to Nether divides by eight and Nether to Overworld multiplies by eight. Height is never scaled in either direction.
Enter X and Z
Only the two horizontal numbers matter, and a minus sign belongs with the number exactly as the game writes it.
Copy what you need
Every row copies on a click: the converted coordinates, the chunk they fall in and the finished teleport line.
Line up the portal
Build the Nether side at the converted spot so the two portals link to each other instead of pairing with something already there.

How to Use the Coordinate Converter
In Minecraft, the Overworld and the Nether are linked by an 8:1 coordinate ratio. Every 1 block you travel in the Nether equals 8 blocks in the Overworld. This converter lets you quickly translate coordinates between these two dimensions so you can plan Nether highway routes, find portal locations, and navigate efficiently between worlds. Because every 1 block in the Nether is 8 in the Overworld, a hub near spawn saves the most travel, and spawn always falls within 128 blocks of 0, 0: the seed analyzer works that region out from your seed.
Enter your X and Z coordinates and select your conversion direction. The tool instantly calculates the equivalent position in the other dimension, along with the chunk coordinates for both input and output. Chunk coordinates are calculated by floor-dividing the block coordinate by 16, which is useful for locating the exact chunk a position falls in.
Common Use Cases
Building Nether highways is one of the most popular uses for coordinate conversion. By traveling through the Nether, you can cover 8 times the distance in the Overworld. If your Overworld base is at X=1200, Z=-400, the corresponding Nether position is X=150, Z=-50. Building a tunnel to that point in the Nether saves significant travel time.
Portal linking is another common scenario. To link portals properly, you need the Nether-side coordinates that match your Overworld portal. Place your Nether portal at the converted coordinates and the game will link them correctly. The chunk coordinate display helps you verify which chunk your portal will load in, which matters for spawn chunk calculations and performance.
The teleport command output lets you quickly jump to the calculated position in-game. Copy the command and paste it into your chat to teleport directly to the converted coordinates. This is useful for server admins testing portal routes or players with operator permissions. A converted position also lands in a chunk, and the chunk border visualizer gives that chunk its numbers, while a teleport that carries rotation or a target selector is the kind of line the command generator assembles.
How the dimensions line up
| The ratio | One block in the Nether is eight blocks in the Overworld, horizontally. Divide X and Z by 8 going in, multiply by 8 coming out. |
|---|---|
| Height | Y is one to one and is not scaled at all. |
| Nether ceiling | The Nether is only 128 blocks tall, y 0 to 127. An Overworld build above y 127 has no matching height on the other side. |
| Portal search | A portal looks for an existing portal within 128 blocks of the scaled position before it builds a new one. That is the single biggest cause of a pair linking somewhere unexpected. |
| The End | No scaling. End coordinates are one to one with the Overworld and no portal maths applies. |
| Rounding | Going into the Nether the result is floored to the block, so half a block of drift in the Overworld disappears. Coming back out the multiplication keeps whatever fraction you typed, and there half a block becomes four. |
The 1 to 8 ratio is not a rule of thumb but the coordinate_scale field of the_nether.json in the game files version 26.2 ships, read 8 August 2026, against 1.0 for the Overworld. The ceiling of 128 blocks is the logical_height in that same file.
The four lines this converter runs, and the distance they imply
Nothing here is rounded for readability. Going in, the tool floors; coming out, it does not, and it also prints the chunk both coordinates land in, because a portal is bound by its chunk more often than by its block.
Overworld to Nether: floor(x / 8) and floor(z / 8), y unchangedNether to Overworld: x x 8 and z x 8, y unchangedchunk = floor(coordinate / 16), for the value you typed and the one you gotthe 128 block search around the target, scaled up, is 128 x 8 = 1024 Overworld blocksThat 1024 is the number worth carrying around. Anything closer than that in the Overworld can be captured by a portal you already built, however carefully you place the frame, and the fix is to build the Nether side first at the coordinates this page gives you.
Frequently Asked Questions
Answers to the most common questions about portal linking and coordinates.
Why did my new portal link to an old one?
Because there was already a portal within 128 blocks of the scaled destination, and an existing portal always wins over building a new one. Keep portals you want kept separate more than 128 Nether blocks apart.
Does the height change between dimensions?
No, Y passes through unchanged. The catch is the Nether's 128 block ceiling: anything you build above y 127 in the Overworld maps onto or above the bedrock roof.
How do I force a pair to link exactly?
Convert the coordinates, then build both portals yourself at those exact blocks instead of letting the game place the second one. Light them from the side you want to be the master.
Does the ratio apply in the End?
No. The 1 to 8 ratio exists only between the Overworld and the Nether. End coordinates match the Overworld one for one.
