Walk down any ambient aisle and your eye lands at roughly 1.2 to 1.5 metres from the floor. That band — the one you see without tilting your head — is the most valuable real estate in the building, and it is sold by the centimetre.
The band reached without crouching or stretching is the one negotiated hardest.

The practice is called slotting, and it runs on fees. A manufacturer pays a retailer to occupy a particular shelf position: eye level for a premium, waist level for less, floor level for the least sought-after slot of all. The fees are rarely published, but they are substantial, and they are why the same category can produce a wildly different margin depending on which product sits at which height. The brand at the bottom is usually the cheapest on the shelf, or the retailer's own label, or both. The brand at the top is often a slow-mover the retailer accepts as part of a wider commercial deal with the supplier.
Eye-level placement works because of what psychologists call processing fluency — the ease with which a product registers. If a thing is in direct sightline, the brain needs less effort to find it, and lower effort reads, unconsciously, as familiarity and preference. Studies in retail psychology have measured uplift from eye-level positioning against the same product moved to a lower shelf; the gap is large enough that brands have fought contractually to maintain it. When a retailer reorganises a category, the shelf negotiation that follows is financial, not aesthetic.

The tilt test is simple: anything requiring you to crouch or crane is paying less for the privilege. Children's products aimed at parental purchase sit at adult eye level; items aimed at pester power tend to drop to child height. That specific adjustment is not accidental — it is the same logic applied to a different pair of eyes.

The shelf is a billboard. The difference is that this one charges by position, not by audience size.
