A Minecraft iron farm works by getting the game to spawn iron golems in a controlled space, then killing them so they drop iron ingots into a chest. Each golem drops 3 to 5 ingots and 0 to 2 poppies, and the rules for getting golems to spawn are different on Java Edition and Bedrock Edition, so a build for one edition will not necessarily work on the other.

Quick answer: iron farm requirements
- Java Edition: villagers summon golems when they panic or gossip. A farm can run on as few as 3 villagers that panic at a zombie they can see but not reach.
- Bedrock Edition: the village itself spawns golems. You need at least 10 villagers and 20 beds, every villager linked to a bed, and 75% of them working at their job sites the previous day.
- Drops: 3 to 5 iron ingots (average 4) and 0 to 2 poppies per golem. Looting does not raise either number.
- Output: around 200 ingots an hour for a small Java build (Switchblade Gaming) and about 240 to 400 for a good Bedrock design (Minecraft Wiki on Fandom).
- Version: no iron golem change appears in the Java 26.3 release notes or the 26.4 Snapshot 8 notes, so the rules below still apply.

How an iron golem farm works
Every design has the same four parts: villagers that trigger golem spawns, a flat platform where the golem appears, something that kills it, and hoppers that carry the drops to a chest. The Fandom wiki’s iron golem farming page says this beats mining or farming zombies and skeletons because iron is dropped every time, in much larger quantities.
The fiddly part is the spawn rules. The Fandom wiki’s Iron Golem page lists them separately for each edition, and this guide follows that page and its farming tutorial.
Java Edition: how golems spawn
On Java, a villager can summon an iron golem when it is gossiping or panicking. The wiki lists these conditions:
- The villager has slept recently.
- It has not seen an iron golem within 16 blocks in the last 30 seconds (villagers scan for golems about every 10 seconds).
- No other villager within 10 blocks has just summoned a golem in the last 30 seconds.
- Enough villagers within 10 blocks qualify: at least 5 when gossiping, at least 3 when panicking.
- The game finds a valid spawn point. It makes up to 10 attempts inside a box of roughly 17 by 13 by 17 blocks around the villager.
That is why Java farms use panic. Villagers that can see a zombie through glass, but cannot be reached, panic constantly, and three of them are enough to meet the panic requirement. The wiki also says the golem needs a solid, flat surface (not a bottom slab) with at least 3 transparent blocks above it.
Bedrock Edition: how golems spawn
Bedrock has no panic trick. A village tries to spawn a golem around its center when all of these hold, according to the Fandom wiki:
| Requirement | Java Edition | Bedrock Edition |
|---|---|---|
| Villagers needed | 3 (panicking) or 5 (gossiping) within 10 blocks | At least 10 in the village |
| Beds needed | Villagers must have slept recently (Switchblade Gaming says 3 beds for its design) | At least 20, every villager linked to a bed |
| Job sites | Not required | At least 75% of villagers worked at their workstation the previous day |
| Trigger | Villager summon attempt, about every 30 seconds | 1 in 700 chance per tick (about one attempt every 35 seconds) |
| Zombie needed? | For a panic design, yes | No |
| Golem cap | No ratio cap on the wiki’s Java page; a golem within 16 blocks blocks a new summon | Fewer than 1 natural golem per 10 villagers (so a second needs 20 villagers) |
| Player distance | Within simulation distance | Within simulation distance (about 8 times the setting in blocks, per the wiki) |
On Bedrock the village center, which is the northwest bottom corner of a bed, bell or workstation, decides where golems can spawn. The wiki says it can shift when villagers link or unlink from beds, and that bells in a farm are a bad idea because villagers try to path to them, fail, and unlink. Its advice is to cluster the beds in the middle and run the spawn platform about 8 blocks out from the outermost beds. The wiki’s two pages give slightly different spawn volumes, so build the platform generously and make sure there is a solid floor under the air space.

A simple Java iron farm: build order
This is the small three-villager design described by Switchblade Gaming, rewritten as a checklist. It is a Java Edition layout; the numbers it quotes are the guide’s, not ours.
- Pick a spot well away from villages. The guide suggests at least 150 blocks, because a nearby village can pull your villagers’ beds into it.
- Villager cell: a small sealed room with three beds and one glass wall. Use solid blocks, not trapdoors, since villagers can open trapdoors and escape.
- Zombie cell: a sealed cell behind that glass wall with a solid roof so the zombie does not burn in daylight. The zombie must stay alive.
- Spawn platform: a flat, solid platform below the cell, with no other flat surface nearby that could steal the spawns. Cover any stray surfaces with glass, carpet or slabs.
- Kill zone: water streams that push golems into a block of lava held by trapdoors, with hoppers underneath feeding one chest.
- Let the villagers sleep once so the beds link, then stay within simulation distance and watch for the first golem.
Switchblade Gaming says a 3-villager farm makes about 200 ingots an hour, about 300 with 10 villagers and about 400 with 20, and that beyond 20 each extra 10 villagers adds only around 5%. The Fandom wiki’s Bedrock figures agree on the shape: a small survival-village farm reaches up to 200 an hour, and the best designs top out near 400.
The wiki also says golems count toward a mob cap, which you can clear by dropping golems down a chute after they spawn (more reliable than a Nether portal). That is wiki advice and we have not tried it.
Iron farm not spawning golems: fixes
| Problem | Likely cause | What to do |
|---|---|---|
| Nothing spawns after a couple of minutes | Villagers have not slept, or are too far from the player | Let them sleep one night and stay within simulation distance |
| Golems appear in the wrong place | Other valid spawn surfaces near the farm | Cover them with glass, carpet or slabs |
| Farm worked, then stopped | Bed links broke after a reload or restart | Break and re-place the beds, let villagers sleep again (Switchblade Gaming) |
| Java villagers do not panic | Zombie out of sight, dead or burned | Check the glass is clear and the roof is solid |
| Bedrock farm dead | Fewer than 10 villagers or 20 beds, or villagers unlinked | Meet the Bedrock table above; keep bells out of the build |
| Bedrock stuck at one golem | The 1-per-10-villagers cap | Add villagers; a second golem needs 20 |
Getting villagers for the farm
You need villagers before anything else. Switchblade Gaming suggests moving them from an existing village by boat. Our Minecraft villager trades chart covers what each profession sells if you keep spare villagers for trading, and the best Minecraft seeds guide helps if you want a village near spawn. For sorting the ingots once they are in the chest, see the copper golem sorting system guide, and for what changes next, the Minecraft 26.4 snapshots roundup.
FAQ
How many iron ingots does an iron golem drop?
3 to 5 ingots, plus 0 to 2 poppies. Looting does not change either, according to the Fandom wiki.
Do I need a zombie for a Bedrock iron farm?
No. Bedrock spawns golems from village rules, so what matters is villager count, beds, job-site work and a valid spawn surface. Zombies are the Java panic trick.
Why does my Java iron farm stop after a while?
The common causes are a broken bed link after a reload, a dead zombie, or a golem already standing within 16 blocks of the villagers. Re-check each in that order.
