How to Make a Nether Portal in Minecraft (Recipe + No Diamond Method)
Short answer: to make a Nether Portal in Minecraft, build a frame of obsidian (minimum 10 blocks, standard 14 blocks) in a rectangle that's at least 4 blocks wide and 5 blocks tall, then ignite the inside with a Flint and Steel. The corners of the frame don't need to be obsidian — you can leave them empty or fill with any block. Once lit, the inside fills with purple swirling portal blocks and you can step through to the Nether dimension. The classic recipe needs only obsidian + flint and steel — but there's also a clever way to make a portal WITHOUT a diamond pickaxe (using lava + water buckets directly).
The Nether Portal is the gateway to the Nether — Minecraft's hellish dimension where you find Nether quartz, blazes, Wither Skeletons, Netherite, and the Trial Chambers' source materials. This guide covers the standard recipe, the no-diamond alternative method, common mistakes, and how Nether-Overworld distance works.
Quick Answer Table
| Question | Answer |
|---|---|
| Minimum obsidian needed? | 10 (corners empty), or 14 for a full frame |
| Standard frame size? | 4 wide × 5 tall (outer dimensions) |
| Inner portal size? | 2 wide × 3 tall (the actual portal opening) |
| How to ignite? | Flint and Steel (right-click inside the frame) |
| Need a diamond pickaxe? | NO — there's a lava-bucket trick (see method 2) |
| Largest possible portal? | 23×23 (Java); standard frame works fine |
| Distance ratio | 1 block in Nether = 8 blocks in Overworld |
| Cooldown after teleport? | 5 seconds — wait before re-entering |
Method 1: Standard Obsidian Portal (Need Diamond Pickaxe)
Step 1: Get obsidian (need at least 10, ideally 14)
Obsidian is created when flowing water touches a lava source block. To make it:
- Find a lava source pool (Nether is full of them; Overworld has lava lakes at low Y levels)
- Place water with a bucket on top of the lava source — it converts to obsidian instantly
- Mine the obsidian with a Diamond Pickaxe or Netherite Pickaxe
Mining obsidian with anything less than diamond breaks it but drops nothing. Obsidian takes ~9.4 seconds to mine even with a diamond pickaxe.
Step 2: Build the frame
Build a 4×5 (outer) rectangle:
- Bottom: 4 obsidian in a row (or 2 if you skip corners)
- Top: 4 obsidian in a row (or 2)
- Left side: 3 obsidian stacked vertically
- Right side: 3 obsidian stacked vertically
Total: 14 obsidian (standard) or 10 (corners empty). The corners can be empty air or filled with any block — the portal still works.
Step 3: Light it with Flint and Steel
Craft a Flint and Steel (1 iron ingot + 1 flint). Right-click on the bottom interior face of the frame. Fire appears, then the interior fills with purple swirling portal blocks.
Method 2: No-Diamond Portal (The Lava + Water Trick)
You can build a Nether Portal without ever mining obsidian. Cast obsidian directly into the portal shape using buckets:
Step 1: Dig a portal-shaped hole
Mine into a wall or hillside to create a frame-shaped depression. The frame's interior should be empty (2 wide × 3 tall). The frame slots themselves should also be empty (you'll fill them with obsidian via lava-bucket pours).
Step 2: Place lava sources in the frame slots
Use a bucket of lava. Pour it into each frame slot — bottom row first, then sides, then top. (Lava only stays as a source block when placed in a 1×1 enclosed space.)
Step 3: Pour water on the lava sources
Use a water bucket. Pour water at the top of each lava block. The water turns the lava source into obsidian.
You now have a full obsidian frame without ever needing a diamond pickaxe.
Step 4: Light it
Same as Method 1 — Flint and Steel on the bottom interior.
This method requires more buckets and patience but is critical for early-game players who haven't reached diamonds yet.
How Nether-Overworld Distance Works
Here's the most important Nether Portal fact: 1 block in the Nether = 8 blocks in the Overworld. If you build a portal in the Overworld at coordinates X=800, Y=64, Z=800, then go through, your Nether portal spawns at approximately X=100, Y=64, Z=100.
This means:
- To travel 800 blocks across the Overworld, you can walk 100 blocks in the Nether instead — 8× faster
- The Nether is the best way to travel long distances
- Build a network of portals — one at base, one at end portal stronghold, one at ocean monument, etc.
Linking portals correctly
When you travel through a portal, Minecraft tries to find an existing portal within ~128 Overworld blocks (16 Nether blocks) of your destination. If one exists, you use it. If not, a new portal spawns automatically.
To force a specific portal pair to link, build BOTH portals at exact 1:8 coordinates. For example:
- Overworld portal at X=800, Z=800
- Nether portal at X=100, Z=100
This guarantees they link to each other.
What's in the Nether (Why Build a Portal)
| Resource | Found In | Used For |
|---|---|---|
| Nether Quartz | Quartz Ore | Comparators, daylight detectors, decoration |
| Glowstone Dust | Glowstone blocks (ceiling) | Brewing, Respiration potion |
| Blaze Rods | Killing Blazes (Nether Fortress) | Eyes of Ender, Brewing Stand |
| Wither Skulls | Killing Wither Skeletons | Summoning the Wither (for Beacons) |
| Ancient Debris (Netherite) | Mining at Y -16 to -8 | Netherite ingots — best armor/tools |
| Soul Sand | Soul sand valley biomes | Summoning Wither, growing nether wart |
| Nether Wart | Nether Fortress chests | Brewing potions |
| Crying Obsidian | Bartering with Piglins | Respawn Anchors |
Going to the Nether is essentially required for any mid-game progression: brewing potions, getting Netherite gear, summoning the Wither, finding the End Portal.
Common Mistakes
"My portal won't light"
Causes:
- Frame is incomplete — make sure the inner area is 2×3 and all 10 (or 14) obsidian blocks are placed
- You used a non-obsidian block — only obsidian works for the frame
- You're using a fire charge instead of flint and steel — both work, but the fire charge requires more precise placement
- Cobblestone or other blocks adjacent — sometimes blocks near the frame can interfere
"My portal disappeared after I came back"
Causes:
- The portal block can be destroyed by ghasts in the Nether (ghast fireballs can shatter portal blocks)
- You may need to re-light the portal — the frame's intact, just no portal blocks
"My portal teleported me to the wrong place"
The 1:8 ratio is at play. Build your Overworld portal at coordinates that match your desired Nether destination. Use F3 (Java) to check coordinates.
Common Questions
Can I make a Nether Portal without any mining?
Yes — use Method 2 (lava + water trick) and you never need a pickaxe at all. You just need 2 buckets, lava, and water access.
Can I use cobblestone or other blocks for the frame?
No. Only obsidian works.
What's the maximum portal size?
23×23 blocks in Java Edition. But you only need 4×5 for full functionality.
Why is there a 5-second cooldown after using a portal?
To prevent rapid back-and-forth which can break game logic. Stand still inside the portal for 4-5 seconds to teleport.
Can mobs walk through Nether Portals?
Yes. Zombies, skeletons, and some other mobs follow you through portals. Wither Skeletons rarely come through but can.
Can pets follow me through?
Not automatically. You must lead tamed wolves/cats on leads to bring them through, or carry them in a boat.
Does the Nether have day/night?
No. The Nether has constant uniform lighting — no day/night cycle.
Can I sleep in the Nether?
NO — beds explode in the Nether. This is a Mojang restriction. Use beds in the Overworld only.
Putting It All Together
Workflow for getting to the Nether:
- Mine 10-14 obsidian (using diamond pickaxe) OR build the frame with lava buckets (Method 2)
- Build a 4×5 frame on flat ground
- Craft Flint and Steel (1 iron + 1 flint)
- Right-click the bottom interior of the frame to ignite
- Step through the purple swirling portal blocks
- You arrive in the Nether — adventure awaits
