Warehouse metrics
The pallet is there.The cube behind it isn't.
Storage density measures how well the cube inside an occupied location is actually being used — a location can hold stock and still ship mostly air behind the pallet face. WareBee measures stored volume against each location's rated cube continuously, so a bay that reads full from the aisle and one that's genuinely packed stop looking the same.

What it is
What's actually inside the cube you already have.
Storage density, on WareBee's digital twin, is stored volume set against rated cube for locations that are already occupied — a narrower question than whether a location holds stock at all. Two pallets sitting in a bay built for three are occupied by the same measure storage capacity utilisation uses, but they're shipping air the density reading catches instead: the space is claimed, not filled. WareBee measures every location's stored volume against its design cube on an ongoing basis, so the gap between the two is visible location by location rather than guessed from how full a bay looks at eye level.
The number moves with how well a pallet's profile matches the bay it's assigned to, how often putaway defaults to whatever location is nearest rather than the one actually sized for it, and how many partial pallets are sitting where a full one belongs. A half-used pallet parked in a deep-lane bay built for a full one wastes the same cube whether the rest of the warehouse is tight on space or not — density is a property of the location, not a symptom of the building running out of room.
Two occupied locations holding the same product families can score miles apart on density, which is proof enough that a single density figure could never survive contact with the range of stock any one building holds, let alone the range across every operation running a warehouse. WareBee instead reads your density against a peer set — matched on order profile, SKU count and footprint — because what a location can reasonably hold depends on what kind of business is putting stock into it, and that comparison is the only one built to say whether wasted cube is a pattern or an outlier.
What moves this number
Where cube goes missing inside a location that reads full.
Each one is measured on your digital twin from data you already generate, so a location reading occupied but underused points at a specific cause.
Profile against bay size
A pallet profile built for one bay size ends up assigned to another, leaving a gap the eye doesn't catch from the aisle.
The twin checks each location's assigned profile against its rated cube, so a mismatch surfaces as a specific location to fix rather than a vague sense that storage feels inefficient.
Stored volume against rated cube
What's physically sitting in a location, measured against what the location was designed to hold, not how full it looks.
Every occupied location gets this comparison continuously, so the worst offenders — the ones shipping the most air relative to their design — surface first instead of hiding inside a site-wide average.
Half-used pallets in full-sized bays
A partial pallet parked where a full one belongs wastes the same cube whether the rest of the building is tight or not.
Locations carrying a fraction of their rated load are flagged and grouped by zone, so consolidating them becomes a route worth walking rather than a scattered list.
Putaway defaults to nearest, not rightest
New stock keeps landing in whatever location is closest rather than the one actually sized for its profile.
Directed slotting proposes the location a pallet's profile is actually built for, so density stops drifting every time a receiving crew takes the shortest walk instead of the correct one.
The bays reading full and the ones actually earning their cube.
A location can look identical from the aisle and mean two different things — one genuinely packed to its rated cube, the other holding a half-used pallet in a bay built for a full one. WareBee measures stored volume against rated cube for every occupied location, so the two stop reading the same and the ones actually wasting cube get named.
From there it's a re-slotting question, tested before it's acted on. Consolidation, spread and re-slotting moves that would improve density are simulated on the digital twin against your real stock and order data first, so you see the cube reclaimed — and the picking impact — before anyone touches a pallet.

Questions
Storage density, cube by cube.
What exactly does storage density measure?
It's stored volume set against a location's rated cube, for locations that already hold stock — not whether a location is occupied, but how much of the space it's occupying is actually being used. WareBee measures every occupied location this way continuously, so a bay that looks packed from the aisle and one that's genuinely full stop being treated as the same reading.
How is storage density different from storage capacity utilisation?
Storage capacity utilisation asks whether a location is occupied at all — a binary reading across the whole footprint. Storage density asks a narrower question about the locations already counted as occupied: how much of the cube inside them is actually carrying stock. A warehouse can sit at a high utilisation ratio and still have poor density, if much of what's occupied is half-used pallets or mismatched profiles, and the two readings are meant to be read together, not interchangeably.
Is there a density level WareBee considers optimal?
No — publishing one would only be honest for a single kind of stock. A zone holding a handful of bulky SKUs will never pack cube as tightly as one holding a large, fast-moving catalogue of small items, no matter how well either one is slotted, so a fixed figure would flatter one operation and unfairly mark down the other for the same effort. WareBee's peer set — order profile, SKU count and footprint — keeps that comparison fair instead.
Why would a location read as occupied but still waste space?
Because occupied only means stock is present, not that the stock fills the cube available. A half-used pallet parked in a bay built for a full one, or a carton profile assigned to a deep-lane bay meant for pallets, both count as occupied while shipping mostly air behind the pallet face. Density is what catches the gap between the two, location by location rather than as one blended reading.
Can fixing density hurt picking?
It's tested before it's trusted either way. Every consolidation, spread and re-slotting move WareBee proposes runs against your digital twin first, so the picking impact is visible alongside the cube reclaimed, not discovered on the floor afterwards. Where similar items need to stay apart to avoid mis-picks or congestion, that separation gets built into the slotting model itself rather than sacrificed for density alone.
Does a re-slotting move that improves density reach the WMS?
Yes. Once a profile correction or re-slotting move is approved, it goes out as the putaway tasks your WMS already runs on, so the location that was quietly wasting cube on the twin is the one that actually gets fixed on the floor. Stored-volume data flows back afterwards, so the next density reading reflects what's genuinely sitting in each location.
