Nether Portal Designs: 16 Minecraft Ideas to Build

A plain obsidian frame gets you into the Nether, but it rarely looks like much. The best nether portal designs turn it into an entrance worth walking through from a cottage doorway to a mossy ruin or a stone arch.

Here are 16 designs, ordered from easy survival builds to advanced creative ones. Each lists the frame size the key blocks and a practical tip and a separate section shows how to build a round or arched surround with a circle generator.

Whatever you pick, the portal itself stays a simple rectangle. Every idea here is decoration built around it, so you can adapt any design to your own base.

Nether Portal Building Rules for Every Design

Every design below has to keep these core rules, so check them before you start building.

Everything outside the frame is yours to design. Only the obsidian ring and the air inside it are fixed.

Which Nether Portal Design Should You Pick?

Use this table to shortlist a design before you read the details. The numbers match the sections below. The difficulty and survival ratings are our own judgement:

Easy, Medium, Hard: how many different blocks a design needs and how much shaping it takes.

Survival friendly, Partly: the design needs Nether items a large amount of one block or a trip to a specific biome.

Survival friendly, No: the design needs creative-scale quantities of an expensive block.

How to Choose the Right Nether Portal Size?

When planning Nether Portal Designs, consider two sizes, the obsidian frame and the decorative surround. The frame is the obsidian rectangle that makes the portal work. The surround is everything you build around it, like a ring or an arch.

Start with the frame because the surround has to fit it. A 4x5 frame is the smallest you can build and the best choice for early survival. It needs 14 obsidian or 10 if you skip the corners. If you plan a round surround go for a 5x5 frame instead. 

Its square opening is much easier to centre and it needs 16 obsidian, or 12 without corners. For a big dramatic gateway in a creative world, try something larger like 7x9 which needs 28 obsidian or 24 without corners.

Want a different size? Add the outer width and height, double the total and subtract 4. That gives you the obsidian count with corners. Subtract 8 instead if you skip them.

Easy Nether Portal Designs for Survival

These easy Nether Portal Designs use common blocks and need very little shaping, making them ideal for an early survival world. 

1. Lava Cast Stone Surround

Frame size: 4x5 outer. Key blocks: cobblestone or dirt a lava bucket and a water bucket.

Build a mould in the shape of the frame, then fill every frame position with a lava source block. Use source blocks only, because flowing lava turns into cobblestone. Pour water over the lava to turn each block into obsidian, then clear the inside, pick the water back up and light the portal. Any stone brick or cobblestone mould blocks can stay as your surround. 

Tip: if you plan to cast more than one frame, a renewable lava source saves you from hunting for lava each time.

2. Cottage Doorway Portal

Frame size: 4x5 outer. Key blocks: stone bricks, stairs, slabs, spruce logs and lanterns.

Set the portal into a small front wall, like the door of a cottage. Put stairs along the top edge as a lintel, add a slab roof and hang a lantern on each side. From the front it looks like a house entrance, so the purple glow comes as a surprise.

Tip: use stone for the blocks that touch the frame and keep wood and leaves a little further away, because flammable blocks can catch fire near an active portal.

3. Garden Pond Portal

Frame size: 4x5 outer. Key blocks: leaf blocks, water, flowers, trapdoors and stone slabs.

Place the frame at the back of a small garden, wrap it in a leaf hedge and put a pond in front. Slabs make good stepping stones across the water so the walk to the portal feels like part of the garden. A stepping stone or gravel route also works well with the path designs you may already have near your base.

Tip: keep the pond on lower ground in front of the frame, and make sure no water or leaves end up inside the opening.

4. Double Portal With a Shared Pillar

Frame size: 7x5 outer. Key blocks: obsidian and a simple stone trim.

Two portals sit side by side and share the middle pillar. Skip the corner blocks, including the top and bottom of the shared pillar, and it needs 17 obsidian instead of the 20 that two separate frames take. A continuous top and bottom edge looks neater and makes it 19. Count in your own world before you mine.

Tip: both portals usually lead to the same place, so build this one for the look and the obsidian savings, not as a second route.

Compact Nether Portal Designs

These designs suit builds where space is tight.

5. Slim Tower Portal

Frame size: 4x5 outer. Key blocks: stone bricks, cobblestone, deepslate and glass panes.

Put the portal on the ground floor of a narrow tower and let the walls rise two or three storeys above it. The height does most of the decorating, so the rest can stay simple. Add a few window slits and a pitched roof to finish the shape.

Tip: keep the blocks above the frame solid, so it reads as a tower and not a floating frame.

6. Wall Inset Indoor Portal

Frame size: 4x5 outer. Key blocks: your base’s wall material, a stone floor and a few lanterns.

Build the frame into the wall of a dedicated hall and hide it behind a matching wall design. The portal stays out of sight while your base keeps a clean and tidy look.

Tip: zombified piglins can spawn at an active Overworld portal, so keep it away from beds, farms and storage.

7. Cave Mouth Portal

Frame size: 4x5 outer. Key blocks: stone, deepslate, moss and a few torches.

Carve a cave mouth into a hillside and place the portal at the back, so it looks like a passage into the mountain. A rounded opening suits this design and a circular mine entrance is a good starting shape.

Tip: light the cave floor well, because dark corners near the portal are where hostile mobs appear.

Themed Nether Portal Designs

Pick the one that matches the buildings around your base.

8. Medieval Gatehouse Portal

Frame size: 4x5 outer. Key blocks: stone bricks, spruce planks, stairs, slabs and iron bars.

Put a short tower on each side of the portal and join them with a roofed bridge above the frame. The portal becomes the gate and iron bars in the side windows add a defensive look.  The roof carries this design, so these roof designs are worth a look for pitched and hipped options that suit towers.

Tip: use a darker trim than the walls, so the frame stands out against the stone.

9. Mossy Ruin Portal

Frame size: 4x5 outer. Key blocks: mossy cobblestone, cracked stone bricks, vines and leaves.

Break up the surround on purpose. Make one pillar taller than the other, leave gaps in the top and let vines hang over the front.  Ruined portals also generate naturally in the game so this style looks familiar to players. Mossy blocks take only two items to make as this guide to crafting mossy cobblestone shows.

Tip: mix mossy and plain blocks unevenly, with more moss near the base.

10. Cherry Grove Portal

Frame size: 4x5 outer. Key blocks: cherry logs, cherry planks, cherry leaves, pink petals and lanterns.

Build a small cherry tree trunk on each side of the frame and let the leaves meet over the top. The pink canopy and the purple portal share a colour family so it looks designed without much detail work.

Tip: build near a cherry grove, so you can collect the wood on site.

11. Blackstone Temple Portal

Frame size: 4x5 outer. Key blocks: polished blackstone, deepslate bricks, crying obsidian and soul lanterns.

Stack two or three layers of stepped arches around the frame, with lighter stone on the outside and darker stone near the opening. Crying obsidian looks like the real thing but cannot be part of the frame, so use it in the surround only.

Tip: blackstone and soul lanterns come from the Nether, so build a basic portal first and make a trip before you finish this one.

12. Japanese Shrine Gate Portal

Frame size: 4x5 outer. Key blocks: stripped spruce or dark oak logs, slabs, trapdoors and lanterns.

Place two tall posts outside the frame and join them with two horizontal beams that stick out past the posts. The portal sits in the middle like the opening of a torii gate. Add a gravel path and a few lanterns for a shrine feel.

Tip: keep the lower beam clear of the opening, so you can walk through without bumping into it.

Round and Arched Nether Portal Designs

The portal frame has to stay a rectangle, but the surround can be circular or arched. A Minecraft circle generator lets you plan the outline block by block, so the curve stays symmetrical.

Frame size decides how easily the surround centres. A 4x5 outer frame is even in width and odd in height, so a circle cannot be centred perfectly on both axes. 

A 5x5 outer frame has a 3x3 opening and a circle with an odd diameter centres on that frame exactly. That frame needs 16 obsidian blocks with corners or 12 without them. The circle is decoration only, so keep the portal opening clear.

13. Round Wooden Ring Portal

Frame size: 5x5 outer. Key blocks: logs, stripped logs, stairs and lanterns.

Build a ring of logs around the frame, using an odd diameter. A 5x5 frame is about 3.5 blocks from its centre to its corners, so a ring of diameter 9 only just clears them while a diameter of 11 leaves a border of roughly one block.  Fill the space between the ring and the frame with stone bricks or a darker wood, keep the opening clear and put a lantern at the top of the ring.

Tip: choose 9 when space is tight and 11 when you want room for detail.

14. Arched Stone Gateway

Frame size: 4x5 outer. Key blocks: stone bricks, stairs, slabs and polished blackstone.

Wrap a semicircular arch around the top of the frame. The top half of a circle makes a clean template, and the half circle generator guide shows how to map it.  The Minecraft archway guide adds block by block layouts, stair and slab smoothing, and a Nether themed variant.

Tip: use a contrasting block for the keystone at the top centre, so the arch does not blend into the wall.

15. Stained Glass Halo Portal

Frame size: 5x5 outer. Key blocks: purple and pink stained glass end rods and obsidian.

Stand a thin ring of stained glass behind the frame, so it glows around the portal like a halo. Keep the ring a few blocks back and hide a few light sources in the base so it looks lit from inside.

Tip: this one suits creative worlds, because stained glass needs a lot of sand and dye.

Advanced Nether Portal Design

Advanced Nether portal designs use larger builds, connected frames or detailed structures to create a standout entrance. 

16. Portal Tunnel

Frame size: several 4x5 frames, one behind another. Key blocks: obsidian and a stone corridor.

Place several frames one behind another along the same line, so they form a tunnel you walk through. Standing anywhere inside connected portals runs the same four second countdown, so the whole tunnel works as one entrance. It makes an unusual entrance for a hub or a spawn area.

Tip: check that every frame in the tunnel is lit before you decorate it.

Nether Portal Safety and Linking Tips

Even the best Nether Portal Designs need a safe exit and protection from dangers on the Nether side. 

• Ghasts: their fireballs can destroy a portal. Surround the Nether side with a blast resistant enclosure such as stone or cobblestone and leave a safe landing area at the exit.

• Piglins and hoglins: zombified piglins can spawn at an active Overworld portal on the bottom frame in Java Edition and next to it in Bedrock Edition. Torches do not prevent this. Active portals repel hoglins.

• Light: good lighting reduces regular hostile spawns near the portal, though it does not stop piglins. These lamp post designs work well near a portal entrance.

• Linking: a portal sends you to the matching spot in the other dimension or to a portal that already exists nearby. Nether distances are one eighth of Overworld distances so turning on coordinates helps you plan where your second portal will land.

• Edition differences: spawn behaviour and a few other details differ between Java and Bedrock. The Java versus Bedrock guide covers the main ones.

Common Mistakes

Most portal problems come from small slips in the surround. Crying obsidian looks just like the real thing but it cannot be part of the frame, so use it only as decoration. 

If you build a ring, use an odd diameter with a 5x5 frame or it will sit half a block off centre. Keep wood, leaves and wool away from the frame as well because a fireball or stray fire can set them alight and the fire can spread. 

Finally, leave enough room to walk up to the portal since a surround that is too tight or too low can block the opening.

Conclusion

Choose from these Nether Portal Designs based on your available materials, building space and survival progress. If you are early in survival, start with the lava-cast surround or the cottage doorway because both use cheap blocks and go up quickly. 

Once you have spare materials, move on to a themed build like the mossy ruin or the Japanese shrine gate or try a round or arched surround if you want something people will stop to look at.

Whatever you choose build the frame and light it first, so you know it works before you decorate. Then add the surround one layer at a time. For a round design open the circle generator, choose an odd diameter for a 5x5 frame and the ring will sit exactly in the middle.

FAQ

Can a Nether portal be round or heart-shaped?

No. Portal blocks only form inside a rectangular obsidian frame. A round or heart-shaped portal is really a surround built around a normal rectangle.

Do you need a diamond pickaxe to build a Nether portal?

You need one to mine obsidian, because only a diamond or netherite pickaxe makes it drop. Without one, you can cast the frame in place with lava and water, as in Design 1 or finish a ruined portal that already has some obsidian.

What can light a Nether portal besides flint and steel?

A fire charge works the same way. A ghast fireball, a lightning strike or fire spreading from a flammable block next to the frame can also light it.

Can I hide the obsidian frame completely?

You can build around it and behind it, so most of the frame can disappear into your design. The inner face and the opening must stay clear because you need to reach the inside to light it and walk through it.

Does the design change where the portal leads?

No. Linking depends on the portal's position and the closest matching portal, not on its decoration.
