As stated in the 2023 Retail Shelf Space Efficiency Research Report, the variation in 500ml can sizes has a direct influence on the display density of products. Let’s consider the case of the standard tank (diameter: 66mm, height: 122mm) and the slim tank (diameter: 58mm, height: 140mm). On a standard shelf board of 45cm in depth, the standard tank can hold 24 tanks (6 horizontal columns × 4 vertical rows) per layer, while the slim tank has 12.1% less diameter. It can be increased to 30 cans (7 columns ×4 rows +2 cans to fill gaps), with space usage increasing by 25% and inventory turnover rate increasing by 18% (calculated based on Walmart’s 2022 carbonated beverage shelf data). For instance, when Coca-Cola Europe reshaped some of its lines into slim cans, every retailer saved a yearly average of 3.2 square meters of shelf space, which was equivalent to having an additional 400 cans of goods on display, which resulted in a 6.7% sales increase.
The 500ml can size significantly affects the cost of logistics and warehousing. The standard tank pallet stacking is 12 layers (1.46 meters in height), but the thin tank must be reduced to 10 layers (1.40 meters) due to a 14.8% increase in height. The decrease in diameter, however, causes the capacity of a single pallet to increase from 4,500 tanks to 5,100 tanks (+13.3%). Anheuser-busch InBev’s 2023 forecasts show that the rear loading rate of transport vehicles with slim tanks has increased from 88% to 94%, saving 1.2 million US dollars per year in freight costs (European figures). However, the stacking force needs to be reverified. The bottom bearing capacity of the slim tank needs to be ≥ 1,800 Newtons (≥ 2,000 Newtons for standard tanks), or otherwise, there is a 0.05% increased likelihood of collapse (Amazon Warehouse Accident Report).
Consumer behavior data shows that 500ml can optimization can enhance purchase intention. Nielsen’s study in 2024 says the slim can ranked 4.3/5 for visual appeal among the age group 18-35 (3.7/5 for the standard can), and it delivered a 19% improved grip comfort (average grip strength test value from 8.2 Newtons to 6.6 Newtons). After the changeover of Japanese Kirin Beer to slim cans, the proportion of freezer displays in convenience stores rose from 22% to 35%, and the monthly sales of a single store grew by 14%, as it was more suited to the size of the freezer area (the height fit rate rose from 67% to 92%).
Rules and sustainability drive the development of 500ml can sizes. The EU’s “Packaging and Packaging Waste Regulation” (PPWR 2025) mandates that beverage cans need to conserve a minimum of 25% of the use of virgin material. slim cans can conserve 11.2 grams of aluminum per can by a weight saving of 9.8%. Carlsberg Group estimates that after the global changeover to slim tanks, the annual carbon emissions will be reduced by 8,400 tons, and the shelf display surface will be increased by 18% (due to the tall, narrow tank body, the visible surface of the labels will increase by 12%). However, recycling link has to adjust, slim tank in sorting line via the speed between 3.2 m/s and 2.8 m/s, in order to avoid the gravity alteration caused by sorting error rate rising (from 1.1% to 2.7%).
Actual case verification of efficiency: In 2023, PepsiCo piloted the slim can in North America. The number of SKUs (inventory units) displayed on the shelves increased from 15 to 19, reducing the decision-making time for shoppers by 7 seconds per case and improving the conversion rate by 9.3%. Suntory of Japan has increased the aisle capacity of its vending machines from 60 cans to 72 cans through the combination of slim cans and shrink labels, extended the replenishment cycle by 14 hours, and reduced operation and maintenance costs by 12%. Data confirm that optimizing 500ml can dimensions can systematically enhance the spatial and cost-effectiveness of the retail chain.
