How to Make a Hopper in Minecraft

Every automated farm in Minecraft has three jobs: grow or spawn the resource, turn it into items, and collect those items. The first two change from farm to farm, but the collection step almost always belongs to one unglamorous block — the hopper. Learn to make hoppers and you hold the key to smelting lines, mob farm collection and item sorters.

What You Need to Make a Hopper

• 5 iron ingots — smelt raw iron from iron ore, or raid the chests of mineshafts and villages
• 1 chest — eight wooden planks around the edge of a crafting grid
• A crafting table for the 3x3 grid

Iron is the only real cost, and five ingots per hopper adds up when a sorting system needs dozens. That is exactly why most players build an iron farm before they build anything ambitious with hoppers.

How to Craft a Hopper

1. Open your crafting table.
2. Place the chest in the center slot.
3. Place one iron ingot directly left of the chest, one directly right, and one directly below it.
4. Place the last two ingots in the top-left and top-right corners, above the two side ingots. The shape looks like a U or a funnel — fitting, since that is what a hopper is.
5. Take the hopper from the result slot.

How Hoppers Move Items

A hopper is a funnel with a five-slot inventory of its own. It constantly does two things: it pulls items from the container directly above it (or picks up loose items lying on top of it), and it pushes items into the container its nozzle points at. When you place a hopper, it connects to the block you were aiming at, so look at the chest, furnace or barrel you want to feed while placing it. Sneak while placing to attach it to a container without opening that container's interface.

Items move one at a time, roughly every 0.4 seconds — about two and a half items per second. That speed is plenty for smelting and storage, but it is also a hard limit: one hopper cannot keep up with a fast farm's output, which is why big collection systems chain several hoppers in a row or use water streams for bulk transport and hoppers only at the intake.

Locking a Hopper with Redstone

Power a hopper with a redstone signal — a lever, a redstone torch beside it, a powered block — and it stops completely. It will not pull, push or accept items until the signal turns off. Despite that, a hopper needs no redstone to craft or to run normally; power is purely an off-switch. That off-switch is the heart of every item sorter: a comparator reads how full a hopper is, and the resulting signal locks and unlocks it to let exactly one type of item through.

Where Hoppers Earn Their Keep

• Furnace arrays: a hopper on top feeds raw ore in, one at the back feeds fuel, one below empties finished ingots into a chest
• Mob farms: hoppers under the killing floor gather drops that would otherwise despawn
• Item sorters: rows of locked hoppers filter a mixed stream into labeled chests
• Brewing and farms: feeding ingredients into brewing stands, or collecting crops knocked loose by water

One variation worth knowing: put a hopper inside a minecart and it becomes a mobile collector that can pull items through a solid block above it — the trick behind many bedrock-level farm designs and unloading stations.
