Automatic Item Sorter
A hopper-based item sorting system that automatically routes items into designated chests. Each filter module sorts one item type using a comparator-based overflow-proof design.
Overview
The Automatic Item Sorter is a storage build whose job is holding, sorting and quickly retrieving large quantities of items; form follows function here, so the layout is dictated by how it works rather than by looks. At 3x6x40 blocks (3 wide, 6 tall and 40 deep) it is compact, covering a 120-block footprint on the ground.
It is rated advanced, so expect to manage significant resources and, in many cases, get redstone timing or precise block-by-block placement correct before it works or looks finished. Following the 35 steps below, plan for about 90-120 min. It is a survival quality-of-life build: the hopper and redstone dust and redstone torch chains in the Automatic Item Sorter cost some iron, but it pays that back every time it sorts a stack for you automatically.
The bulk of the work is the 64 hoppers that form the main body, alongside 6 different materials in total (about 176 blocks and items all told). The working heart is the redstone — redstone dust, redstone torch, comparator and repeater — which is what actually delivers the sorted items. Lighting comes from redstone torch, which both finishes the look and stops mobs spawning in or on the build.
Materials Needed
Gather the 64 hoppers first, since it is the most-used block; the remaining 5 materials are accents and fittings used in smaller amounts. Mine roughly 10-15% extra of the main block to cover mistakes and a few decorative changes on a build this size. Make sure the redstone components (redstone dust, redstone torch, comparator and repeater) are crafted ahead of time, as those are the pieces most likely to be missing mid-build. Quantities are sized for the dimensions shown, so scale them up proportionally if you build a larger version.
| Material | Quantity |
|---|---|
| Hopper | 64 |
| Chest | 32 |
| Redstone Dust | 32 |
| Redstone Torch | 16 |
| Comparator | 16 |
| Repeater | 16 |

Step-by-Step Overview
A high-level construction order for the Automatic Item Sorter, from the ground up. Each phase below covers several of the 35 in-game steps.
- 1Decide how many item types the Automatic Item Sorter must hold, then mark out the 3x40 grid so the rows of containers line up cleanly.
- 2Place the chests or barrels of the Automatic Item Sorter in even rows with a walkway, leaving a block behind each for the hopper that feeds it.
- 3Run the hopper lines and redstone dust, redstone torch and comparator that move and filter sorted items into the right containers — this is the part to test slowly.
- 4Add a single drop-off chest feeding the Automatic Item Sorter so handling sorted items starts the moment you dump loot in.
- 5Light and decorate the room, then stress-test the Automatic Item Sorter by tossing in a mixed double-chest and watching everything land where it should.
Build Tips
- 1Each filter needs exactly 1 target item and filler items in the hopper.
- 2Use renamed items as fillers so they do not stack with sorted items.
- 3Always include an overflow chest at the end for unsorted items.
- 4Build vertically if horizontal space is limited.
Tips & Variations
Keep mobs out by spacing your redstone torch so no floor tile or nearby surface in the Automatic Item Sorter sits below light level 1; a single dark corner is all it takes for something to spawn inside.
To resize the Automatic Item Sorter, keep its 3x40 proportions and grow both axes together; stretching one direction alone tends to make it look thin. A half-size or double-size version both work as long as you scale the 176-block material list to match.
For a different look, swap the hopper in the Automatic Item Sorter for another palette that fits your biome: the shape stays identical, but the colour and texture of the main block changes the whole feel of it.
The most common mistake on the Automatic Item Sorter is wiring before testing: power one section of the redstone dust and redstone torch at a time and confirm it fires before you bury the redstone, because a single misplaced repeater driving the sorted items is painful to find once it is hidden inside the wall.
Frequently Asked Questions
How hard is the Automatic Item Sorter build?
It is rated advanced, so expect to manage significant resources and, in many cases, get redstone timing or precise block-by-block placement correct before it works or looks finished. It is laid out in 35 steps and takes about 90-120 min to finish.
What blocks do you need for the Automatic Item Sorter?
The main block is hopper (around 64), and the full list runs to 6 materials — mostly hopper, chest and redstone dust. Altogether that is roughly 176 blocks and items; the complete table with exact counts is above. It also needs the redstone components that make it work: redstone dust, redstone torch, comparator and repeater.
How big is the Automatic Item Sorter?
It measures 3x6x40 blocks — 3 wide, 6 tall and 40 deep — which is compact and takes up a 120-block footprint. You can shrink or enlarge it by keeping those proportions.
Is the Automatic Item Sorter survival-friendly?
It is a survival quality-of-life build: the hopper and redstone dust and redstone torch chains in the Automatic Item Sorter cost some iron, but it pays that back every time it sorts a stack for you automatically.
Does the Automatic Item Sorter work on its own once built?
Yes — once the redstone dust, redstone torch and comparator are placed and timed correctly it produces sorted items automatically; the only manual job is emptying the output chest, and you may need to stay within simulation distance for it to keep running.
What makes the Automatic Item Sorter different from similar builds?
It is best understood through its focus on sorter, automatic and hopper. Those traits drive the material list and layout described above, and are what set this storage build apart from a generic sorted items build.
