The 202 (2.13-inch) and 211 (2.25-inch) are probably the most common beer can diameters, but each size has its own specific roles in packaging and branding. 211 diameter is the standard for most 12 oz cans in the US, commonly seen in the craft & commercial beer space. The diameter strikes a balance of being sturdy but also allows for enough size to create expansive branding real estate with more intricate graphics to grab the eye of shoppers. The diameter of a 211 is the preferred choice for placement on shelves in stores, as more than 70% of consumers recognize their choice through what they see, according to the Can Manufacturers Institute.
The 202 dimensions, which are 2.13 inches in diameter, is typically used for the type of slim cans that are designed to hold a smaller serving size (often 8 or possibly even as small as 10 ounces). It is commonly used for specialty or limited release beers where a streamlined shape matches premium brand positioning. The reduced diameter also increases the overall strength of a can which is especially important for carbonated beverages that are subjected to pressures of up to 90 psi. Another benefit is the smaller diameter supports better stacking and storage in tight spaces, which would make it a sensible choice for bars and stores that are using narrow shelving.
Biggers sizes, such as the 300 (3 inch) for 16 ounce cans have opened up during era of craft brewing considering that brewers appearance to put out masser portions. This larger bottom is able to hold more volume without significantly increasing the height, which appeals to consumers looking for a robust beverage. It also allows more room for branding where unique design elements set the craft beers apart from regular mass market counterparts. In 2023, Beverage Packaging Insights published research reporting that 45% of consumers are encouraged to sample a product due to its unique can design which indicates that craft labels with a wider beer can diameter are perhaps even more enticing.
Choosing can diameter is a crucial component for brewers sourcing beer can size options, because it needs to meet both the brand image and functional requirements, ranging from cooling efficiency to storage capacity. The right diameter size helps to create an attractive product and allows its brand positioning since many consumers prefer distinct, bold packaging.
