Bin utilisation is usually low because bins are sized for the largest SKU that might occupy them, not the average. Mixed bin sizes raise utilisation considerably at the cost of a more complex slotting decision.

Frequently asked questions
What is bin utilisation?
The share of bin volume actually filled with stock. It is almost always lower than people expect, because bins are sized for worst case rather than typical case.
Should I use mixed bin sizes?
Above a few hundred SKUs, yes. Three or four bin sizes matched to SKU dimensions can raise effective capacity substantially without any building work.
How much stock should sit in the pick face?
Enough to avoid stockouts between replenishments, and no more. Excess in the pick face wastes the most expensive storage space in the building.
Does slotting matter more than bin size?
For picking speed, yes. For capacity, bin size matters more. Most warehouses have room to improve on both and address neither.
