Can one create a fully functional 3x3 portal? (That's 3x3 on the inside, and 5x5 on the outside)

If you're wondering why I would want to do such a thing, it's purely for aesthetic reasons. I have a room with a wall 3 wide built deep within my base and it would be more trouble than it is worth to resize the room. Hence a 3x3 portal would be perfect.

  • Portals to nether are 2x3, but if you have the Enhanced Portals mod, you can make portals of any size; i.e. 1x1, 5x10, 1x2, and so on.

As of snapshot 13w37a, you can now create portals of any size between 2x3 and 21x21. This is a feature in Minecraft 1.7.


As of Minecraft 1.5_01, only 2x3 portals can be created (via Obsidian frames) to provide transport to the nether.

You can use inventory hackers to give yourself some portal blocks (data value 90) to place down, seeing as it gives you no advantage as such it's not really cheating...

    Portal blocks not inside a frame and not touching other portal blocks will despawn as soon as they receive a block update, apparently. The result is that you can place (and use!) a single portal block just fine, but as soon as you place a second beside it the first despawns (because at least one of its other sides is non-obsidian, non-portal), and the despawning of the first is a block update so the second immediately despawns. Consequently, creative mode and inventory hacks that give you placeable portal blocks only let you create 1x1 portals. Feb 6, 2013 at 9:18

According to what I know, the 1.7 update allows you to build a portal at any size, but it can't be any smaller than 3x2. So, you can make a Square 3x3 portal, If that's what you're talking about. if you have a 23x23 room, internal space. then you will be able to build the maximum internal space portal, 21x21 internal space

    This just repeats what 3ventic's answer says. Nov 5, 2013 at 20:35

You can hand-place portal blocks (not the obsidian frame, but the actual purple portal blocks) using MCEdit, which is an external world editor. By hand-placing them, you can make a portal of any shape and size.

    You should offer more information. How would one do it with MCEdit?

    @3ventic I fixed it to say what they should have said. Sep 7, 2013 at 19:42

    Well, really it's not hand placing, you have to use mc edits external program to do it, if you're going to use a mod/program I'd just use TMI or NEI to spawn the block into your inventory EDIT: Doesn't work, block update, I forgot. Still, getting enhanced portals would be easier than getting mcedit if you'll only use it once
