There are programs and mods that display coordinates for aligning portals perfectly. That is what I used to place 3 portals within 8 blocks of each other. I used the SimpleMap mod, but there are other mods like sign tags for example, and there is even a program called MinecraftGPS that you can use to show your coordinates. I use these tools instead of counting blocks or time to precisely align portal placement.
I'm starting to hollow out a 1000x1000x128 area in order to store all my belongings.
It will take a while but it will be worth it, risking your precious blocks to a rogue creeper just isn't worth it.
It may or may not take hundreds, maybe even thousands of hours to complete this storage room but in the end creepers will be unable to destroy my stuff and then i can build my treehouse in peace.
Updated "the Basics" with a new rule of thumb, the minimal distance.
8. The minimal distance between portals is at least 80 blocks on the surface, 10 blocks in the Nether as in my example, but for the best results I suggest at least 128 blocks between portals on the surface, and 16 blocks distance in the Nether. There seems to be a 1 portal per Nether chunk (16x16 area) limit...
This is wrong. The only reason it doesn't work is because your initial portals aren't perfectly aligned. Align them perfectly and enjoy the fruits of your labour. It seems like you've done extensive testing as this method is exactly how I've been fixing my portals yet I can recreate tiny distances perfectly. Note that there needs to be perfect alignment in both planes for small distances to work 100%. It's a bit of a pain and its practical uses are questionable but it works.
You are correct and i have adjusted that line.
The minimal distance is only 1* block of space in between Nether portals if they are aligned perfectly.
*Building a portal with zero space in between another portal seems to simply extinguish the other portal.
It appears the test portal i've been using to test minimal distance is not aligned properly... i will have to conduct my tests again on a new portal.
For now I still recommend 64(8) and 128(16) as the minimal distances to absolutely ensure successful portals.
Thanks for the response. I haven't had a chance to test this yet because the portals I am talking about all happen in my Let's Play series and I am currently 10 episodes ahead so I am waiting a few more days before I record anymore. I trust that this will work but I will let you know either way.
I'm 99.99% sure this will work if you follow the instructions correctly.
BUT in a way i hope it doesn't...
Im still waiting for a portal problem that i simply can't fix.
Problems are how we will learn solutions.
I've had numerous problems with portals and i've fixed them all.
If i can find a new problem that i haven't fixed before this will give me new insight into the problem.
So please, if you try and try but still can't fix your portals I'd love a crack at it myself, upload your save and i'll see what i can do.
Updated "the Basics" with a new rule of thumb, the minimal distance.
I actually have 2 portals in the Nether separated by just 1 block in one plane. I have 3 portals very close together in the Nether(less than 8 blocks), and they all work. The key to creating these portals close together was building them in pairs instead of allowing the game to spawn any of them.
To create these pairs, I built the frame(s) in both the Nether and the surface before I activated either one. This works because the game will first check for any portal frame on the other side before creating one. If you have already built a frame on the other side in the right location, or very near it, that frame will then link.
Sorry you must have missed my post.
I've had portals work with less than 16 blocks between them in the Nether, but i believe they were in their own Nether chunks.
To avoid frustration make sure there is at least 16 blocks in between your Nether portals, 128 blocks in between your surface portals.
Smaller Nether distances as close as 2 blocks away are theoretically possible but unlikely to work unless you can see where your chunks are with a map editor and avoid building Nether portals within the same Nether Chunk or juust get lucky with your placement.
For example: Building a portal in the center of a Nether chunk will restrict any portals from working as 2 way portals within 8 blocks in every direction, building on the edge of a Nether chunk will restrict 2 way portals for 1 block in one direction and 16 blocks in another direction.
If you can find out where your Nether chunks are you could possibly build portals with only a single block in between them but this is just a hypothesis for now.
Stick to 128 surface blocks, 16 Nether blocks between portal for worry free portal placement.
I too have portals only a few blocks apart on one of my maps but have been unsucessful at recreating the short distance with 100% accuracy.
I'm pretty sure it has to do with the Nether Chunks.
I'm guessing that you have built your portals on the edge of chunks and both portals are inside of their own chunks.
Try and build your nether Portals 3 blocks away in other directions, you will run across problems building multiple Nether portals within the same Nether chunk.
As i said, this is a variable rule of thumb and I'm still working out the specifics but i feel that I'm getting close.
I just now tried your guide, and it worked without a flaw! Now I've got to redo my portal room in celebration of a functional portal!
I do have one little tip for lazy people: MC edit. Select one block of portal A (referring to the guide) then fly over to portal D (the duplicate portal created on the surface), and select a block there, too. I don't use MCedit very much and don't know how to do anything fancy, but it gave me a little prompt that showed the dimensions of the selected area. For me, it was 60x160 (WxL.) Divide those two numbers by 8 (7x20 for me), and then build the portal in the nether in the corresponding area.
If your width was 1 (assuming you selected the same block in both portals; I selected the lower right in both to be sure), then your nether portal will be directly behind the misplaced portal. If there IS a width, then it gets slightly more annoying. It's easy to build a few blocks out in one more direction, but you have to pay attention to orientation. To help with this, it's going to be in an either dangerous or unsuitable area, but it's best to simply pay attention to the direction you're facing. It's helpful to know that you come out of a portal facing the same way you entered it in
Awesome!

So if there are any portal experts here, I have a question.
Based on prior experience, I was thinking of making a portal network in my new save with the following rules:-
a} No portals less than 50 overworld blocks apart, minimum.
b} Portals are primarily built in the Nether. The first portal will be the only overworld portal manually built.
c} Portals will only be built above sea level, and in relatively open areas, to minimise obstruction issues.
Are these good rules of thumb, to try and make working portals? If anyone can add more information to this, I'd appreciate it.
In my last save, I had a problem where I built two gates in the overworld; one near my spawn, and a second at a mine some distance away, in an underground gateroom. I realise now that building two manually in the overworld was my first mistake, but the end result of it was that several new portals got built, but I could enter any portal from the overworld, and coming out of the Nether, they would all exit from a new randomly generated portal near my spawn. (Although not the one I'd built)
I wanted to be able to go from the portal near my spawn, into the Nether, and come out from my portal in my mine gateroom, but I think the first problem was that my mine portal was built around 18 blocks below sealevel. Both portals ended up initially generating two gates in the Nether that were literally one block apart from each other, but they both went back out to the spawn portal.
Both gates also generated on top of a cliff, however; and then ghasts blew out all of the hellstone underneath them, so I could exit the gateroom portal and literally fall straight into an ocean of lava below. I am assuming it would have worked if I'd destroyed that portal, and built another around two blocks below it, but I never tried that.
Those rules are more like guidelines along the path of conquering portals.
a) I've never tested the minimal distance, it could be around 50 blocks on the surface, 5 or blocks in the Nether, i'll test it.
**Correction**
a) After extensive testing the minimal distance is at least 64 blocks apart on the surface, 8 blocks in the Nether, further testing is still required to pinpoint the exact minimal distance.
:cool.gif: This makes it a lot easier but isn't necessary if you know how to fix them.
c) An unnecessary restriction once you know how to fix them vertical placement is irrelevant.
I have made a simple guide for fixing portals found here:
I've had to fix that problem many times, it's the same basic problem with an extra twist.
That would be awesome.
I tried destroying some portals but it didn't really work. I didn't want to destroy the portal in the nether because I had spent 2 days making a minecart system to it.
Please excuse my laziness but i didn't have to create a new picture for this explanation.
This is your situation.
Everytime you create a new portal (portal D) it just links back to your Portal B.
Here is how to fix.
Find out where your game wants to make Portal C, in this picture it is marked with an X.
You have no choice but to build Portal C yourself in the Nether.
1. Count the distance between Portal D and Portal A, in this case you said it was 30 minutes away.
2. Divide by 8, 30/8 = 3.75 minutes.
3. Face the direction of Portal D
4. Enter Portal A, walk 3.75 minutes and build Portal C.
I can tell you right now there is an obstruction in the way. Since it is 3.75 minutes wide it is probably a lava lake or a pretty massive mountain.
Clear the obstruction, build Portal C.
Time the distance between your new portal C and portal B, it should be exactly 1/8th the distance between A and D in the same exact direction.
I would love to know how to fix the problem that I currently have. Which is any portal I make takes me back to the last portal that was made in the nether. I walked literally 30 mins in one direction in the real world, created a portal and when I enter it once again I am sent back to the last portal that was created in the nether. It is kind of cool because I can always get back to my base, but it almost kind of sucks because I can never use a portal in the nether to go anywhere in the real world other than my base.
I will create a diagram for you.
I've had to fix that problem many times, it's the same basic problem with an extra twist.
2. Building a portal on the surface will spawn a portal in the Nether
3. Building a portal in the Nether will spawn a portal on the surface.
As far as I can tell, these statements are incorrect or incomplete. Portals spawn either on activation ( ) or when you first travel through one. I'm not sure which. If a portal frame is already placed in the proper location on the other side, then the portals will just link, and no portal generation takes place.
Good job on the guide. It's a simpler explanation than others I've seen. I also like portals the way they are now.
You are correct!
It is only after you light/enter the portal that a new portal is created in the other world.
This is essentially how I fixed up my own portals back when I was first exploring the Nether. I'm still not 100% sure they're in exactly the right places, but they work both ways and don't seem to be making extra portals, so that's enough for me.
This is a really good explanation and demonstration of how to fix them up, though. Hopefully it'll help people fix up their portals too.
Incidentally, another useful tip is that the vertical distance doesn't matter. So once you've managed to work out where your portals need to be, you can move them directly up or down in either the Nether or the surface world as needed. (Build the new ones one at a time and make sure they're working properly before you destroy the old portals.) I've used this trick to put my Nether portals into a protected underground corridor -- and it also means that I can enter my sea-level base portal, walk a short distance along a level corridor in the Nether, and be transported to my near-bedrock mining zone. (A drop pool would have been faster, but my mining zone is quite a fair distance away as well.)
Absolutely correct!
Vertical placement does not matter. I have moved a portal from the very top of the Nether all the way down to the lava lake level and they still link up perfectly fine.

I will use these mods to solve the minimal distance problem without resorting to hours of trial and error.
